How Much Does it Cost to Build a Sailboat at Home?

As you have likely already done so, the math between building your own boat and buying one may be a huge difference. Likewise, you may even enjoy the challenge of taking an older boat that is gutted and restoring with parts from a kit to build one new again.

But how much does it cost exactly to build a boat from the comfort of your own garage or workshop? The prices are going to vary dramatically depending on your situation and material needed to get the job done. In addition, the time that it takes to complete this will also vary.

Sail plans are rather inexpensive if you are aiming to build a small boat. These plans allow you to see the workings of the boat design and what you need to build the boat.

Without these plans, you will not know the exact details of the design and it can cause major issues with the boat’s hull or other areas of the boat. Think of these as the backbone or instructions of the boat’s infancy before being built.

Price Per Square Foot

You should assume to pay anywhere between $300 to $600 per square foot if you are interested in building a boat. Buying a kit outright can be a good way to save time, but oftentimes these do not come with everything you need.

Instead, you should try to source as much of the materials at the best price as possible. Thinking ahead is part of the process and you might be able to score a deal at a lumber yard or hardware store for parts.

Boat Designs Matter

The design of the boat will be much different from one boat to the next, regardless if they are the same size in length. If you are pondering boats that range anywhere between 16 and 20 feet, you should factor in the shape of the hull, any rigging, and various appendages.

Prices tend to increase when there are more complexities within the designs. If you are considering a kit with more details than others, you will also have to pay more for the designs on that as well.

Kits Can Differ

It is important to understand that all kits are not going to be the same. As you gander at sailboat kits online to stitch together, you need to thoroughly look over to see if you have everything you need before buying.

It would also be at your advantage to ask the seller if any additional parts or supplies are needed. This may change your dynamic on the kit buying process and you may pass up one for another if it has everything you need. An all-inclusive kit may cost several hundred, if not thousands, of dollars more to have the convenience of everything in the bundle.

Construction Approaches

Some boat plans may require you to have certain tools to get the job done. This means special saws or planers, which the average person simply does not have.

Purchasing specialty tools might be expensive upfront and hard to find depending on what it is. Your best bet would be to check locally for others trying to sell their tools or consider a boat plan that does not require extensive tools to finish the job.

How Long Does it Take to Build a Sailboat?

An easy to build sailboat could take a while to build from scratch. Many different variances come into play that are difficult to pinpoint for everyone. But how long is that exactly and how will your experience play into this?

A fun project to sail in the wind could take you several months to well over a year depending on the boat plan and how big your boat is going to be. In addition, the materials all need to be accounted for prior to starting in the event a hardware store does not have them in stock.

Time Varies

The time that passes for simple boat designs on small sailing vessels can be done in a few weeks. This is assuming you have everything you need and work non-stop around the clock.

Certain complex situations may make the process long, such as the difficulty of working with some materials. If you are a skilled laborer, it may take you half the time compared to a novice. The amount of time it can take will vary on your availability and skill level.

Planning ahead will undoubtedly offer the most time-saving features. It also helps if you can tackle parts of the project at your own pace.

Complexity of Design

The design of the boat may make the construction process longer. For example, it may take you longer to build a catamaran compared to a similar lengthed monohull.

More complex designs might require more materials, therefore making the process a bit longer to complete. Furthermore, you will also need more experience working with difficult designs and that will affect you more as a newbie.

Be sure to manage your expectations well and do not allow yourself to become too stressed over this fun project. If you can, seek expert boat building advice from a local builder or the company you purchased sail plans through.

Quality Materials

The quality of the materials will matter significantly when building a boat and will greatly affect the time it takes to construct it. Handling fiberglass or carbon fiber might require specialty tools, while wood also demands a certain level of craftsmanship.

If you are not skilled at working with the material at hand, it might affect the quality of the build and you may have to go back to fix mistakes. This will definitely add more time to your project, because mistakes are bound to happen with your first project.

To save time, consider adding the tools and materials throughout the year or as often as your budget allows. You may want to try testing your skills on fiberglass or other materials to get a feel for how to work with it.

How to Build a Wood Sailboat

Introduction: How to Build a Wood Sailboat

I've been wanting to combine my two favorite hobbies - woodworking and sailing for a long time, so I thought I'd build a boat. It's got classic lines and looks so dazzling in the sunshine that people constantly stop me at the boat ramp to ask me about it. There's something unbelievably rewarding about building something like this from scratch. This is definitely a boat that is much better built than bought . Here's how I did it.

The boat takes about 100 hours to build. I did it over 3 months, working a little bit just about every day and full days when my schedule permitted.

It will take about $1,000 in total to build if you buy everything at full retail cost (not including tools you might need to buy), but you can spread that across the length of the project. For example, you only need to buy one $30 sheet of plywood at a time, take it home, draw out the parts (loft) that fit on just that sheet and cut them out. That will take a couple of hours right there. Some boating supply stores (chandleries) might let you setup an account which might give you a discount if you tell them you're building a boat.

All of the skills needed to build a sailboat can be learned slowly, one step at a time. For example, if you've never fiber-glassed plywood before, just practice on a small piece first to get your confidence up. This was my first boat build, so I did a lot of learn as you go . Not only am I going to show you the right way to successfully build your own sailboat, but I'm going to share with you the mistakes I made along the way to hopefully save you from repeating them.

The end result will be a very attractive little 8 foot long pram, that is easily made out of 4x8 sheets of plywood that is light enough to put in the back of a small pickup truck or roll down to the local lake on the optional dolly. Anything longer would require you to either make a scarf joint (which is a bit tricky) or buy longer sheets of plywood (which is considerably more expensive).

What you will need:

Boat building plans

8 panels of 1/4" oak plywood 4'x8'

Pencil, Sharpie, ruler, tape measure, yard stick, etc.

Long flexible straight edge

Box of 1" brad nails

2 gallons of epoxy resin

1 gallon of epoxy hardener - SLOW

1 quart silica thickener

5 quarts wood flour thickener

1" masking tape

Japanese pull-saw

Table saw (helps, but optional)

Round-over router bit

Flush trim router bit

Palm/random orbital sander

220 sanding discs

Combination square

Drill bit set

Drill bit extension

Basic hand tools

Small diameter wire or zip ties

Wire cutter

12 C-clamps - 3"

Mixing cups, mixing sticks, rubber/nitrile gloves

16' x 60" of 6oz fiberglass cloth

2" plastic spreader

Gallon of waterproof glue

Glue roller

Silicone bronze screws

Stainless steel fasteners

Small blocks

Gudgeon & pintle - dinghy size

Patience - large

Elbow grease - large

For more detailed explanations on each step and more specific info/reviews on the materials and parts used, check out my boat build blog: www.Midnight-Maker.com

Step 1: Cutting Out the Parts...

First, you'll need boat building plans. I purchased some very nice ones from a popular boat building website because I had a specific style in mind to build, a "pram". It's a Norwegian design with lots of buoyancy in the bow and building a pointy boat is a little more difficult. There are a bunch of free boat building plans (search "dinghy") online. Also, I wanted my boat parts to fit in a standard (read cheap) 4'x8' sheet of plywood. It also had to be light enough for me to load/unload/move myself. This boat weighs in at about 70 pounds. When on the custom dolly I built, it's very easy to move from the parking lot to the lake.

Next, you'll need to draw out the parts of the boat full-sized onto the plywood (lofting). I actually did this step on hardboard/masonite because I wanted to make templates of all the parts in case I ever wanted to build another one.

This step requires you to be very meticulous. Carefully transfer the measurements (offsets). They may or may not look correct because it's very non-intuitive to look at curved boat parts that are laying flat. Some parts actually bend the opposite way you think they should. To make the curves, I nailed a bunch of 1" brads into the panel and used a long, flexible straight edge (yard stick, etc.) bent to follow the curve, then I traced the curve with pencil/Sharpie. Once I removed the brads, I had perfectly smooth curves. Keep in mind that with the side panels that are symmetrical to both sides of the boat, only draw out one version and cut two stacked sheets at a time. This ensures the boat will not be lop-sided. Make sure to immobilize the two sheets together with screws outside of the boat parts or use double-sided tape/clamps, etc. to keep the parts registered properly.

Using a Japanese pull-saw allows you to control the cuts very carefully and it can follow the graceful curves. They cut on the pull stroke which means they're very easy to control. Make sure you leave a bit of your cut line, meaning cut just outside the line. This allows you a bit of a safety margin and you can always sand to the line to sweeten it up. This is where the elbow grease really kicks in. It takes hours to cut out the hull panels by hand, but it's worth it. I tried cutting the first part out with the jigsaw and it wandered all over the place and quickly cut inside the line before I knew it. Also, a jig saw blade can lean to one side which could mean two panels might not be the exact same shape. Using hand tools is a classic way to do woodworking and is a very gratifying process. With hand tools, things happen slow enough for you to be in total control, whereas power tools can quickly do unexpected damage. With the understanding that you're building a classic boat, using hand tools wherever possible is part of the philosophy.

The plans I bought were in metric and called for 6mm (1/4") and 9mm (3/8") plywood, but I wanted to make everything out of 1/4" plywood so the thicker parts in the plans were glued together with two layers of 1/4" (so at 1/2" they were a bit thicker than designed). I actually liked this because it made the boat feel sturdier and of course it was cheaper that way. The trade-off was that the boat would be a bit heavier.

For any of the parts that need to be doubled-up/laminated (e.g. the transoms), now is a good time to do that. Make sure you use "waterproof" glue instead of "weatherproof" glue like I did...

Spread a thin layer of glue over one of the "bad" sides (plywood usually has a good side and a bad side, glue bad sides together so good sides show on both outside faces), making sure it's completely covered (I used a special glue roller), then carefully place the other half on top. Align all of the edges together, then clamp them in place. Now put heavy things carefully on top to press the parts together. The glue should be dry in about 6 hours.

NOTE: It's considerably easier and safer to do any woodworking processes to the parts before you assemble the boat. This way, you can safely clamp pieces to the work bench and cut out handle holes, etc. Since my boat is a "lapstrake" design, I had to route a rabbet (groove located on the edge) carefully on the bottom edge of each side panel. This creates a shoulder for the parts to sit on, positively locating them while you're stitching the panels together. Likewise, the grab handles in the transoms are much easier to cut out before putting the boat together.

Also keep in mind that any mistake will be considerably more painful the further you are along in the build. For example, if I biff cutting out the grab handle holes while they're just loose pieces rather than when they're a permanent part of the boat, it's much easier to recover - just make another transom. If you had to patch a hole in the boat, it would be difficult and possibly never look perfect. No pressure...

Step 2: Assembling the Hull...

Once you have the bottom and sides cut out, you can start to "stitch and glue" the hull together. This is a technique used usually for smaller boats to be able to pull the hull form together without the need to build a frame or mold (which can take almost as long and as much wood as the boat itself).

I built a gauge stick to make sure my holes were perfectly spaced at 4" at 1/2" in from the plywood edge. It was 1" wide so either edge was the required 1/2" from the centerline. I worked my way down one side of each of each mated seam and drilled all those holes at once while the panels could lay flat on the bench. Make sure to use a backer block to prevent tear out on the back side, even with such a small drill bit.

With one mating panel drilled with a 1/16" drill bit, hold the mating panel in it's relative position. I used some spare twine to wrangle my panels into the proper orientation as I was marking them. Make a pencil mark where the mating hole should be, remove the pre-drilled panel and drill the second set of holes 1/2" in from the edge. This makes sure there's enough strength to hold the boat together.

The first pass on the stitches is just to get the hull together structurally. You can always go back and make the stitches fancier/tighter and tweak the position of the panels.

The stitches go from the inside out. Cut 6" lengths of wire and bend them into long, narrow U's that are the width of the distance between the holes. Stick the ends through the holes and carefully twist the tails together on the outside of the hull, making sure not to damage the plywood. If you're using zip ties, then the holes you drill will need to be bigger and you'll have to start on the outside, go in, turn around, then back out, then "zip".

Make sure your panels' rabbet shoulders are resting securely on the mating panel and carefully tighten all the stitches. For my boat, once I had two panels stitched to the bottom panel on each side, it was time to attach the transoms (ends). Once all of the exterior parts are stitched together, you should have something that looks like a boat. It will be a little rickety at this stage, but that's okay.

NOTE: In the photos I took of my build, you'll notice that the transom doublers (reinforcers) aren't in place. That was because I was following the instruction manual, but I think that was a mistake, so I highly recommend laminating (gluing) the doublers to the transoms before you stitch the boat together.

Step 3: Reinforcing the Hull Joints...

Now that the hull is stitched together, flip it over upside down. You'll be surprised at how stiff it is, considering how difficult it was to wrangle all those panels into position. Be careful, there's lots of poky wire ends sticking out all over the place.

I used a technique called "tabbing", meaning I made small, structural tabs from thickened epoxy that fit between the stitches, then I removed the stitches and made one long, larger fillet to connect the hull panels together.

Make sure your panels are perfectly aligned and tightened. I used a nipper to lop off most of the tails so they wouldn't get in the way, but that left very sharp spikes.

Make sure your boat is square. Take diagonal measurements from corner to corner, make sure the boat parts are parallel to each other, etc. because if there's a twist in your boat, the next step will make it permanent, which will affect the boat's performance.

Now mix up a batch of epoxy and silica thickener according to the manufacturer's directions (meaning each type of epoxy has a different resin to hardener ratio) until it's between the consistency of thick ketchup, but runnier than peanut butter (make sure to mix the 2 parts of epoxy together first very well before adding a thickener). Too thick and it won't fill the void, too thin and it'll run down inside the boat. Both are bad. I used a small syringe to inject the mix into the V intersection between the panels and checked underneath/inside to see if there were any runs.

Once the epoxy has partially set, use a glove wet with denatured alcohol to smooth out the "tabs" so they fit inside the V groove and don't extend above the intersection between the panels. This will give you good practice for the seams that will show on the finished boat. Be careful of the wire spikes.

Repeat this process for every seam on the hull. Let it cure overnight.

Once the tabs have cured, carefully remove the stitches. If the wire seems to be epoxied permanently to the hull, heat the wire with a lighter. That will soften the epoxy enough to pull the wire out. Be careful not to scorch the boat (you don't want a Viking funeral). Now repeat the thickened epoxy process for each overlap, except this time each seam will need to be one long, smooth joint. Let it cure overnight. This goes a long way in making the boat hull structural.

Step 4: ​Fiberglassing the Hull...

Now that you've got a permanent hull shape, it's time to make it waterproof and rugged. Fiberglass and resin over plywood is a tried and true Do It Yourself boat building technique which makes it strong and light.

Mask off the bottom panel and roll out your fiberglass cloth. Smooth the cloth out very carefully so as not to snag or tweak the fibers' orientation. Mix up an unthickened batch of epoxy (it will be the consistency of syrup). Starting at the stern, pour a small puddle of epoxy and spread it out nice and thin. You should be able to squeeze most of the epoxy out of the cloth, leaving only saturated cloth with no dry spots (which will appear white) but the weave should still be showing (meaning no extra epoxy is pooling). You should easily be able to see the wood grain through the cloth now.

Let the epoxy partially cure and using a razor, slice the dry fiberglass cloth away on the taped seam. Then remove the masking tape. Let the epoxy cure overnight.

Flip the hull over and mix up a batch of epoxy that is the consistency of peanut butter. I masked off the joint, but this step is optional, but keep in mind that it will be visible if you plan on finishing the interior bright (varnished wood). It's not as critical if you're painting the interior. With a plastic spreader, carefully make a large radius transition (fillet) between the bottom panel and the first side panel (garboard). Remove the masking tape when the epoxy mixture is partially cured and carefully scrape/wipe any unwanted mixture. It's much easier to remove now than having to sand it all off later. At this point, it's also a good time to fillet the transoms to the sides using 3/4" radius tabs between stitches and 1" finished fillets after you've removed the stitches. Let the fillets cure overnight.

Now, repeat the entire fiberglassing process on the inside. Except instead of just doing the bottom panel, make sure both the bottom and the garboard are fiberglassed. This is basically the waterline of the boat. The fillet should allow the fiberglass cloth to smoothly make the bend between boards. Remove the excess cloth when partially cured and let sit overnight. Some people fiberglass up onto the transom at this stage which will make the boat stronger, but that means you have to have already filleted the transoms to the bottom.

Step 5: Installing Interior Parts...

The bulkheads get stitched in place just like the panels. They will make the already stiff (and much heavier boat) completely structurally sound and push/pull the sides into their final shape. Then make 3/4" "tab" fillets between the stitches to lock them in place, remove the stitches and make long, smooth 1" fillets. The smaller fillets will get covered by the larger fillets. I used two different modified plastic spreaders to do this step. Each spreader was cut with a box knife and filed/sanded into its final shape.

While you're doing the previous steps, if you're in a time crunch, go ahead and build the daggerboard trunk. It's made of numerous parts that are pre-coated with a couple layers of unthickened epoxy, then glued together with silica-thickened epoxy. This makes it strong and waterproof as it will be below the waterline so must be completely waterproof.

The daggerboard trunk is the most important part of the boat, especially if you're making a sailboat version (this boat can easily just be used as a rowboat). Not only does it support the center seat (thwart), but it has to transfer all of the force from the sail to the water and if you run the boat aground, it takes all the shock loading from the daggerboard.

The daggerboard gets filleted into place like everything else. Make sure it's perfectly on the centerline of the boat as that will affect its sailing characteristics.

Next, let's make the daggerboard slot in the center thwart. I set up a straight edge with a spiral upcutting router bit. Make sure to enlarge the slots at the end of the center thwart so that it can fit around the fillets of the center bulkhead. Now is the time to ease the edges of the center thwart because you'll be sitting on it a lot, so it needs to be comfortable. Because it's so thin, I only routed the top edge of the center thwart that shows and just hand sanded the edge underneath (it's very problematic to use a round-over bit on the second side of a thin board). Paint all of the thwarts with three coats of unthickened epoxy, especially the undersides. Once the woodworking is done, the thwart can be epoxied into place with peanut butter (or you can jump to cutting the daggerboard slot in the bottom of the hull). Make sure the thwart fits snugly in place. Drop dollops of peanut butter on the top edges of the center bulkhead and daggerboard case and spread it out evenly (make sure none gets inside the slot to interfere with the daggerboard). Firmly seat the thwart (pun intended) into the goop and weight it down. Let it cure overnight.

While you've making sawdust, cut out the mast hole (partner) in the forward thwart by drilling holes in the four corners (for the square mast we're going to make), then cut out the sides, file it smooth, then round over the top edge with the router.

Any time after the bulkhead thwart fillets have cured, you can seal the airtank chambers. Paint the bottom, sides, inside of the bulkhead and transom up to the level where the thwart will be.

Step 6: Rail & Sailboat Parts...

There are several processes in this boat building instructable that can be done concurrently. While you're waiting for the epoxy on one part to cure, you can be doing woodworking or epoxying another part. This step illustrates that point. While you're waiting for the epoxy on the rub rail (outwale) to cure, you can be fabricating the sailboat accessories (e.g. daggerboard, rudder, tiller, spars, etc.).

In order for the outwale to be thick/strong enough to be effective, you'll need to laminate it in two strips on each side. You can't bend a single piece that thick around the curvature of the hull without either breaking the wood or softening it by steaming it which is a complicated process.

Take a strip that's half the final thickness and a little longer than the boat edge (I made mine a bit beefier), mix up some peanut butter with the colloidal silica and carefully spread it on the inside of the strip. Starting at the stern, clamp it in place, perfectly align it with the top edge of the plywood. Now you have a long, springy lever to bend the wood strip along the compound curve. It dips both vertically (shear), and bows out at the widest part of the boat (beam), then back in toward the bow. At least every foot, clamp it as you go, moving forward. More is better. Toward the bow, the strip will get stiffer as it gets shorter. Once clamped in place, scrape/wipe off all the squeeze-out. It's much easier to remove now than after it hardens. Let it sit overnight. You'll have to repeat this three more times, meaning this step takes four days (if you're using "slow" epoxy hardener).

During those four days that you're dealing with the outwale, you can make major progress on the sailboat parts. They're completely separate from the hull. If you're just making a rowboat, then you can skip making these parts.

The daggerboard and rudder are cut out and laminated. Then a bevel is ground onto the leading and trailing edges to make it slice through the water more efficiently. Then they're covered in layers of epoxy. The mast step is assembled. This has to be very strong because all of the force of the sail is transmitted to the boat through the mast step and the mast is a very long lever arm. The rudder cheek plates and tiller also have to be assembled similarly to the daggerboard case.

NOTE: Whenever there's a hole to be drilled into any part of the boat, you must take additional steps to make sure the water doesn't penetrate and damage the wood. The correct procedure is to drill an over-sized hole, completely fill that hole with epoxy (I usually put a piece of masking tape on the back side to act as a dam), then once the epoxy cures, re-drill in the center of the epoxy plug the correct hole size. That makes each hole in the boat possibly a 2 day process, so plan accordingly. You can also use 5 minute epoxy to knock out a bunch of holes quickly, but be careful, they're not kidding. This stuff gets rock hard very quickly and will permanently glue anything touching. This is exactly how you drill the hole for the pivot point for the rudder/cheek plate assembly. If the pin is 1/4", then drill 1/2" hole and fill that with epoxy. Now the 1/4" hole will fit nicely in the center and be completely waterproof.

Since all the parts need several coats of unthickened epoxy and they just about all have holes in them, I hung them up with some twine and painted them on all sides, one layer at a time, for several days. Make sure the rudder doesn't get too thick to fit inside the cheek plates.

Step 7: Making the Spars...

More sailboat parts you can make while waiting for other parts to cure are the spars, the structural parts that support the sail. The mast is another glue up. I used 3 - 1x3's of hemlock. A relatively soft wood, but with a nice tight grain with no knots. A mast would break at a knot, regardless of how strong the wood is. Using the waterproof glue, align the pieces as perfectly as you can then clamp up the assembly and let dry overnight. Then run it through a table saw to get the final dimensions. Use a router and a round-over bit to ease the edges. Cut to length and sand the sharp corners. It should fit easily, but snugly into the forward thwart.

The boom (bottom of sail) is a little more complicated. Cut out the gooseneck (boom pivot point) by using a hole saw first, making sure to clamp it securely to the workbench, then cut out the profile. This gets attached to another piece of 1x3 hemlock, after it's been cut to length and the edges have been rounded over.

The yard (top of sail) is easy. Just cut to length and round over the edges. Drill and fill any holes in the spars at this time. You'll need at least one hole on each end to lash the sail grommets to.

This time, everything gets covered with several coats of varnish, epoxy is not necessary. The varnish protects the wood from water and UV damage.

The reason we had to make at least the mast at this point is because we'll need it in the next step to establish the location of the mast step.

Step 8: Finishing Up the Interior & Exterior...

Once the outwales are successfully attached, trim them flush with the face of the transom(s). While you're at it, use a flush cut saw (with no sawtooth offset to mar the wood) to trim the sides flush with the transom. This will show you how well your injected silica mix worked earlier. Now you're ready to install the mast step.

The mast step must be precisely located on the floor (sole) of the boat to give the mast the proper angle (rake). This is very important because it directly affects the boat's ability to sail upwind. Using your mast, insert it into the forward thwart (partner) and into the mast step. With the mast at a 3° angle (mostly vertical but with a small, yet noticeable and graceful tilt toward the stern of the boat), trace the location of the mast step. Use a combination square to make sure it's perfectly aligned side to side (athwartship). You can now set the mast aside. Drill and fill holes in the bottom of the boat so that you can securely screw the mast step from the outside of the hull. The mast base must also be epoxied to the sole with peanut butter. After it's screwed into place but before the epoxy cures, make sure to test fit the mast again and verify the rake angle is correct. It would be a little messy at this point if you had to tweak it, but at least you wouldn't have to cut it off.

Now comes the most unpleasant part of the whole build. On your hands and knees, make a 1" radius fillet on the underside of every part in the boat. I didn't worry about making these pretty, just structural and water tight (these create the flotation tanks that keep the boat from sinking if you capsize). Let that cure overnight.

Next is the scariest part of the build, making the slot in the hull for the daggerboard. Using a drill bit extension, from the inside of the boat, reach down through the daggerboard case and drill a hole at each end of the slot through the bottom of the boat (make sure to use a backer board). Drill a couple holes in between, then take a jigsaw and connect the dots. This weakens the hull enough so that the router won't tear out any extra wood. Note, this step can easily be done prior to affixing the center thwart. Using a flush trim/laminate router bit, let the bearing run around the inside of the daggerboard case. This will make the hole in the hull perfectly match the slot. This is important because you don't want a shoulder on the inside for the daggerboard to hit and you don't want to damage the waterproof lining of the case. Last, ease the sharp edge of the daggerboard slot with the router and a small radius round-over bit.

The skeg must be cut to fit the curve of the hull (rocker), then using silicone bronze screws, attach it to the hull using the same drill and fill/peanut butter techniques. Make sure to snap a chalk line on the centerline of the boat for reference. Then make a 1" fillet where it meets the hull which will support the skeg and make it strong. The skeg keeps the boat tracking straight in the water. I optionally used some fiberglass cloth to cover the skeg and overlap onto the bottom to make the entire assembly stronger and more waterproof. The skeg will take the brunt of the abuse when launching, beaching, loading and unloading, etc. I also installed a stainless steel rubstrake on the aft end of the skeg with this in mind. In wooden boat building, silicone bronze screws are often used because they won't corrode when encapsulated like stainless steel screws can.

Install the skids parallel to the skeg. These are solid pieces of hardwood because they will also take a lot of abuse when the boat is sitting on shore, protecting the thin hull from rocks, etc. They get installed the same way as the skeg, although it's a little tough to bend the wood along the rocker. Scrape off the excess peanut butter once they're screwed in place.

I also installed the optional outboard motor pad at this point because I plan to use an electric trolling motor on the back to quietly putter around the lake in the evenings to relax with the family after work.

That should be the last parts that go into making the boat!

Step 9: Finishing the Hull...

Now comes the last dash to the finish line. One of the more tedious steps is that you now have to sand the entire boat. I actually built the entire boat inside, but for the sanding stage, I took her outside. Several hours of sanding all of the fillets nice and smooth. Everything will show in the finished product whether you paint the boat or leave it "bright" (unpainted). If you've been careful about cleaning up the peanut butter as you go, you should be able to sand the boat with mostly 220 grit. Be careful not to sand through the thin veneer of the plywood. After the sanding is done (make sure to use a dust mask), vacuum the entire boat and then wipe it down with a tack cloth to remove any dust. I also reversed the hose on the shop vac and used it to blow the sawdust off since I was outside.

Next, you must coat the entire interior and exterior with 3-4 coats of unthickened epoxy. This makes the entire boat waterproof. It will also give you an idea of how beautiful the wood will look when varnished. This is why a lot of boat builders decide to leave their boats bright so the beauty of the wood shows through.

Mix up 1 cup batches of unthickened epoxy and pour out large puddles onto the surface. Taking a foam roller, distribute the epoxy in a smooth coat. Now take a wide foam brush and gently smooth (tip) the rolled out surface. This should remove any lap marks or bubbles. Move along to the next area, making sure to not touch the wet parts. Also, make sure no dust or bugs get on your finish or it'll mean even more sanding later.

Start with the exterior first. It'll be much easier to get good by practicing on the convex surfaces. The interior is more tricky because you want to prevent sags and pooling by only applying very thin coats.

Make sure to check with the manufacturer's directions during this step in case you have to deal with "blushing", a thin layer that can sometimes form on the surface of epoxy when it cures. This could cause your layers to not stick to each other. If your epoxy does blush, it's easy to just wipe the entire boat down with a rag soaked in acetone after each coat has cured. Some people sand between coats of epoxy. This is how you would make an extremely smooth/shiny finish, so if you want your boat to be museum quality, invest the effort. I'm planning on banging my boat around so opted out of an extreme, fancy, mirror finish.

I was originally going to paint the exterior of the hull, which would require priming and painting, but I'm leaving it bright for the time being. The good news is that you can always paint later if you change your mind, but if you paint it and change your mind, it's tough to go back. There aren't a lot of pics of this step, which took a couple of days because there wasn't much visible progress after that first coat went on. At this point, any surface that's not painted should be varnished using the same "roll and tip" method as the epoxy, with the optional sanding between coats. Note that epoxy has no UV resistance, so to keep your boat from getting sunburned, you must either paint or varnish every surface. Giving a boat a "museum quality" paint and/or varnish finish can literally take as long as building the boat.

Step 10: Making the Sail...

Another step you can do while other parts are curing is make the sail. This particular design uses a "lug" sail, a classic looking sail for small boats with wood masts. It increases the sail area (therefore the force generated by the wind) without it having to be as tall as a modern sailboat mast made of aluminum. There is a kit from an online sailmaking company that you can get for a reasonable price. The Dacron cloth panels are all cut out by a CNC machine, so they fit perfectly together. I used a regular, domestic sewing machine, not an industrial one. The only time I had trouble was when sewing through all 7 layers at the reinforcement patches. When I got to those parts, I had to manually push down on the foot of the sewing machine with a flat-bladed screwdriver (minus) to help push the needle through the Dacron. We jokingly call Philips head screwdrivers "plus".

The panels/parts all come labeled. The directions were a bit confusing because they suggest you make sub-assemblies after the fact to make wrangling the large sail easier but they mention it after you've already sewn the large panels together. It's important to understand what parts go together while the panels are still small and more manageable. For example, the batten pockets are tricky enough to build on a single panel, much less the finished sail. Building the sail was about as difficult for me as building the boat, but it was worth it.

The lug sail gets reinforcement patches on all four corners where you attach it to the spars (bend), and there's also a reefing point for when the wind starts to pick up (freshen). Modern sails have three corners (Marconi rig).

I opted for the less expensive white Dacron sail kit, but there's also a classic red (tanbark) colored kit that's $100 more expensive. Before I sewed a single stitch, I carefully traced every part of the sail kit onto painter's tarp poly film so I can always use the templates to build another sail, all I need to do is buy the tanbark cloth.

Step 11: Rigging Your Sailboat...

This seems to be the trickiest part for most people, probably because there are numerous ways it can be successfully rigged, depending on your experience, preferences or criteria. It's confusing because you have to know what the finished setup will look like in your mind while you're staring at a pile of ropes. I chose a setup that allows the most room in the cockpit for a full-sized adult, so the mainsheet is led forward of the skipper's position. This keeps the skipper's attention forward so they're looking where they're going. I have another boat where the mainsheet is behind the skipper and it takes some practice getting used to.

The lines I made up (rope becomes a line when you give it a job description) were the halyard (hauls the sail up), the mainsheet (adjusts the angle of the sail to the wind = trim) and a traveler bridle (where the mainsheet attaches to the boat). I got fancy and spliced all my ends, but you can just as well use a bowline knot.

I installed a cheek block at the top of the mast instead of the large diameter hole in the directions. I wanted the halyard to run as smoothly as possible when setting the sail. Then I installed a pair of cleats at the base of the mast, one for the halyard and one for the downhaul (cunningham). With both of these lines pulling in opposite directions, it locks the sail in place, flat, so it effectivley acts like a wing. The main halyard attaches to the gaff with a snap onto a padeye. This allows easy on/easy off when rigging at the boat ramp. I also used a small loop (parrel) around the mast and through the eye to keep the gaff located close to the mast. I looped the downhaul over the boom and down to the cleat to try to keep the gooseneck from twisting. Note, except for the blocks, just about all of the hardware used on rigging a boat this size can come in stainless steel or brass/bronze, depending on the look you're going for. If you plan on installing oarlocks to row the boat, this decision becomes even more important to the final look of the boat.

For the mainsheet, I made a short bridle between the handles on the transom with a small eye tied in the center. This allows a place for the snap on the end of the mainsheet to attach to. I could've just as easily allowed the snap to slide, which would give the bridle the function of a traveler, but would affect its pointing ability (sail upwind). The mainsheet is then run to a block on the end of the boom, then to another block in the middle of the boom. This leaves the main cockpit area unobstructed with running rigging. Make sure your mainsheet is long enough for your boom to swing forward of 90° to the boat, with enough to still come back to the cockpit for the skipper to control. A stop knot at the end of the mainsheet will keep the mainsheet from getting away from you and give you something to grip.

The rudder pivot hardware (gudgeons and pintles) must be installed perfectly vertical and on the exact centerline of the boat so that she will sail well. Drill and fill the necessary holes for this hardware. Be careful with the spacing. It's designed to be easily installed and uninstalled while underway.

With this particular rigging layout, when under sail, the skipper must constantly keep the mainsheet in hand, which is a good idea anyway for safety reasons (if you get hit by a gust of wind = puff, you won't get blown over = capsize). The tension on the mainsheet is easily manageable for any size skipper. On larger boats, the mainsheet is held by a fiddle block with a cam cleat, which is not necessary for a boat this size. With that being said, a possible future upgrade would be to install a block and a camcleat somewhere on the centerline of the boat so that more advanced sailors wouldn't need to constantly have to oppose the tension on the mainsheet. Of course the trade-off would be the hardware would probably be somewhere you might want to sit.

Another upgrade I figured out after actually taking her sailing would be to rig up a bungee/shock cord system that will hold the daggerboard both in an up and down position. With the current setup, the centerboard is held down by gravity and must be pulled out of the slot when beaching.

Step 12: Go SAILING!

Because I wanted to be able to go sailing by myself if needed, I made a dolly out of 2x4's and large pneumatic tires (which makes the dolly float). The dolly fits securely between the center and aft thwarts when driving out to the lake. The sides on the dolly lock against the skids on the bottom of the boat so it can't twist. Roll the sail up with the spars and wrap it with the main halyard. At the designed length, the mast doesn't fit inside the boat, but it seems a bit long, so some people have cut the mast down enough so that it fits inside the boat.

Out at the lake, unload the boat, slide the dolly underneath and you're ready to roll down to the ramp. At the launch, roll the boat out into the water until it floats off the dolly, toss the dolly off to the side out of everybody else's way. Drop the daggerboard into the slot and install the rudder assembly. Facing into the wind (important), stick the mast into the receiver hole (partner), tie off the downhaul (cunningham) and hoist the sail until the downhaul is tight, then cleat off the main halyard. Reave the mainsheet (run the line through the blocks) and you're ready to go sailing.

I've found that this boat sails very well. The lug sail makes it very easy to sail upwind (weather helm), it's a little more tender for a large adult, more so than a boat with a hard chine, like an El Toro/Optimist but it's a lot more graceful looking. The payload is very reasonable for a boat this size. My wife and son can easily (and safely) go sailing with me and I don't even need anyone's help to get it rigged and launched. All in all, this is one of the best projects I've every built. I hope you too can discover the joy of building your own boat and then take her sailing. Remember, in sailing, the wind is free, but nothing else is...

This is my very first Instructable after many years of referencing this excellent site to build numerous cool projects (you should see my next post). Anyway, I hope you enjoy it and please feel free to ask any questions you may have and I'll do my best to answer them. I'm planning on building a larger boat in the near future so stay tuned...

Open/Dayboat, Free Sailboat Plans

Everyone who digs boating has heard of the Hobie Cat, the sleek little catamaran that burst on the scene and captured the attention of all the fast-action sailors.

Marked by asymmetrical hulls and special trampoline supports, the Hobie can reach speeds above 20 mph and perform with a rare agility.

But it has one drawback.

It costs mucho dinero.

Thus, we introduce the Hobby Kat, sailboat plans, a build-it-yourself version of the “Hobie” that should cost from half to a third of the commercial version. If you have the moola, of course, go for a Hobie and have the time of your life on the water.

If not, try our Hobby

The homebuilt is not quite the same.

But she sails sweetly and fast—qualities which have made the “Hobie” popular

Even in a light air she’ll slip through the water at a fast clip.

She has no centreboards, leeboards or keel, and needs none.

The inside of each hull has built-in lift, like an airplane wing, so that as the boat heels and one hull digs in the boat is pulled back to windward.

Click Here for the Plans

She can run in very shallow water and the rudders kick up for beaching.

You can carry her on a trailer or even disassemble her.

Many a “stink pot” addict will take a second look at Tern because she planes in modest breezes, is easy to handle, and her streamlined prow arid pod-shaped, “inland scow” type hull offer slight water resistance. Then too, there’s a charm about the tiller of a sailer that’s not matched by the wheel of a motor-powered boat. Part of it is the challenge of making the most of nature’s free-wheeling breezes. Even with her 72sq.ft of sail, this Free Sailboat Plan is remarkably stable, and packs as many as four persons aboard

For thousands of inland lakes, Tern is the answer to sailing water sport, she is rugged and easy to launch

And she’s remarkably easy to build.

Falcon is a small, speedy, sporty sailboat which handles well. Tests on the original Falcon showed that she could easily out-distance boats of comparable size such as the one design class Snipe and Comet sailers.

And she will pace neck and neck with 18 footers with considerably greater sail spread.

This strong, beamy, eight-foot pram may be sailed either cat-rigged or sloop-rigged.

The dagger-board may be adjusted forward to balance the helm when sailing with the addition of a jib sail.

Oars or a small outboard motor may also be used to power this versatile Free Sailboat Plans.

Dart” is a small two or three person sailing craft, designed for use on protected waters such as bays. lakes, rivers or wherever sheltered waters are found. Its construction will repay the builder handsomely and provide a fast sailing craft, light in weight, easily transportable and cheap to construct with all difficult joinery eliminated

It provides thrilling and economical sport.

The 'Crescent', designed by C. T. Allen, is the ideal sailboat for day sailing on a small lake, river, or protected waters of a bay.

Centreboard design (Fig. 2) reduces Crescent's draft, so Shallow is not a problem.

Its broad beam of over 5½ft. makes it an ideal family boat because there is room for a cockpit large enough to accommodate four adults or two adults and three kids, and side and forward decks big enough to stretch out on when sun bathing.

"Jewel" is a 16' Crescent Sailboat being built by Mike Allen from the free sailboat plans by C.T .Allen in the 1958 "Boat Builders Handbook". And what a superb job Mike is doing check out his photos here .

Sailing enthusiasts and backyard boat builders are not likely to find free boat plans for a sailing pram that can be built faster, lighter, stronger, or less expensively than Graefin-10. Two men can begin work on a Friday evening and have a smart, lively 10-ft. 85-pound sailboat in the water by Sunday evening (it’s been done).

Zephyr Is a refinement of a type of boat developed by the English for use in the rough open waters of the English Channel. Not only is it fast under sail, but it can stand up under punishment. And it’s light enough to be easily loaded atop an auto or light trailer.

Breeze-Baby

Skimming off a brisk wind or with the wind abeam, Breeze-Baby actually planes with one person aboard. Despite her rowboat lines that make her easy to build, she handles easily under her simple sail, an ideal first boat. Simple lines are adapted to plywood construction that’s strong, light and that keeps Breeze-Baby’s bilges dry

You can take her with you atop your car or on a lightweight trailer for summer fun wherever you vacation or get in a week-end’s sailing.

Cat’s Paw is easy to build because of the straight-sided hulls. The sheer line is flat and that simplifies building the form. Bow and stern are straight, so there’s no cockeyed bevel to fit and fuss with

She Is an Ideal boat to learn or practice sailing in because she will forgive so many mistakes.

Boat Building Methods

Bruce roberts sailboat and powerboat designs, & boat plans for the diy boat builder, bruce roberts international, the original bruce roberts design office began life in 1968 in, queensland, australia. we are still located in queensland, australia and in 2010 had a name change to fine line boat plans and designs.   read more on our history on about us ..

For over forty five years the Bruce Roberts Group, with input from many designers, shipwrights, builders and owners, have been drawing detailed boat plans for sailboats and powerboats with the DIY boat builder specially in mind. These boatplans & designs range in size from 5.8 mts to 20 mts and can be built in many different materials.  We have boat plans & designs for building in steel or aluminium in either multichine, radius chine or round bilge hull forms.  Most boat plans & designs are also in fibreglass using either c-flex, foam sandwich or single skin hull construction methods or in cold moulded ply or strip plank using what is commonly know as wood epoxy boatbuilding. Thousands of boats marketed as Roberts designs have been built in backyards and successfully sailed around the world.

Our range of boat plans & designs  include the:-  Roberts, Waverunner, Trader, Spray, Centennial Spray, Coastworker, New York,  Adventurer, Tom Thumb, Henry Morgan, Offshore, PCF, Mauritius / Norfolk, Classic, Power Cat, Trawler Yacht and the Longboat. 

In our archives are nearly all the boat plans & designs that we have designed over the years.  If you are resurrecting an older Roberts boat then it is very likely we will still have the drawings to help.

The emphasis has always been on safety and the fact that when building your own boat you can not only build for less but can build what you want, not what a boat salesman tells you you need . The boat plans come with full size frame patterns and detailed construction drawings as well as information on building one's own tools, fitting self steering vane, mast, trailers (for trailerable boats) etc.

DIY Sailboat Kit: How To Impress Your Wife By Saying You Are Building A Boat From Scratch

Sure, you can always just buy a little sailboat for taking with you during the summer’s weekend trips.  But why not impress the wife and kids by pretending to build one from scratch?   That’s exactly what you can do with the DIY Sailboat Kit.

Made by the Balmain Boat Company, it’s a DIY sailboat kit that includes everything you need to assemble your own little sailer.  Everything is pre-cut, too, so you don’t have to do any difficult cutting work (not that you have to admit that to anybody else) — just follow the instructions to put the individual parts together and you’ve got yourself a real boat you can take down the waters.

The DIY Sailboat Kit includes all the individual plywood pieces, screws, nails, glue, and even marine sealants for building your boat, as well as the mast, boom, gaff, sail and rope for catching the winds during your boat rides.  You’ll need a hammer, a caulking gun and a drill, though, so make sure you have those ready if you’re trying to impress the wife and kids with your crazy boatbuilding skills.  It ships in a flat-packed box measuring 3,000 x 700 x 230 mm that turns into a 3,000 x 1,300 x 515 mm boat once completely put together.

The Best Tennis Aids And Gadgets To Help You Ace Your Next Game

According to the product page, the boat takes approximately 30 hours to complete, so it will probably take you about 60, which still sounds awesome.  You’ll need to give the epoxy and sealant two weeks to set, though, so don’t just drive down to the beach as soon as you finish the thing.

You can order the DIY Sailboat Kit directly from the BBCo website, priced at $2,590.

DIY aluminium sloop: how to make your own metal cruising yacht

• April 16, 2018

Oloff and Muir de Wet, two South African brothers, taught themselves welding, CAD programmes, keel casting and so much more en route to building their dream cruising yacht.

One of the highlights is where Palley warns against being “overly dedicated to comfort”. He urges us to

“break the pattern of thought that says more comfort means a better life. The good life has damn-all to do with comfort. The good life has to do with stretching mind and body…”

Ongemak , the name of our boat, is the Afrikaans word for discomfort. It was also the name of our grandfather’s farm, and from the moment that Muir and I came up with this name, it stuck, it grew, and sometimes became akin to a living force behind the project. It was a name that at once reflected our roots in the platteland (remote country) far from the sea, as well as a sense of adventure and a willingness to sacrifice comfort and comfort zones for new, uncharted horizons.

The beginning

Muir and I had our first serious taste of sailing (albeit not of salt water) about 10 years ago when, together with our friends Tinashe, Elisma and Adolf, we acquired a Miura, a 31ft fin-keeled sailing yacht designed by Oswald Berkemeyer, on the Vaal Dam. An article like this is no place for assigning blame, but it was mostly Hennie Olivier’s fault.

Having returned to South Africa after a year-long transcontinental trip, Muir and I were telling Hennie the story of how we had spent our last evening on the beautiful Dakar Yacht Club balcony enjoying sundowners. Staring out over the boats, we’d already started dreaming of new frontiers. So Hennie immediately got up to fetch his Sailing magazine from the car, and together we started going through the classifieds. He later drove from Bloemfontein to advise us when we bought the Miura.

Having a Miura on the Vaal proved to be perfect for our metamorphosis from land animal to amphibian. The Vaal can occasionally be nasty, but it is mostly friendly, and a Miura is always a very forgiving boat.

But we also learned that owning a boat is about a lot more than sailing. It is a way of life, and being part of a community of often eccentric individuals. It is interacting with nature in the most straightforward way, and (if we are honest) often has a lot more to do with the actual keeping and maintaining of a boat than sailing it. This played a major part in what followed.

Human nature means that we always want more and, sadly, sailing does not cure us of this malady.

Soon I started thinking of improvements to the boat – small ones at first and then increasingly larger ones. It didn’t help that I was busy with a PhD in geometry, because often during my years of study I found that when duty called, some other project promising pleasure started calling like a siren in an even louder voice. So slowly an idea started brewing…

My mother often says that Muir and I are twins born two years apart, and it is true that we share a like-mindedness that is sometimes uncanny. So it came as no surprise that, when we discovered we’d both moved on to a new page in our lives, it was in fact the same page (he was now working in aerospace medicine in the Middle East and I was a lecturer in Pretoria).

This is what our new page said:

it makes no sense to sell the best eight hours of every day. Life is short and the world is big. Let’s move to Cape Town and build a yacht.

So in our late 30s we both quit our jobs. We said goodbye to the office, confident that we would soon master the mystical skills of welding and the wielding of power tools. Success was a given, because when he was seven and I was nine, we built a really nice tree house. We even had the dog up there.

The design criteria

This is what we wanted:

• A sloop for extensive cruising for two couples
• Minimum maintenance and simple systems
• Energy efficiency and complete solar reliance

We wanted an empty shell so we could design our own interior layout and systems, so we began looking for a ready-made hull and deck. But somehow, even though we looked at quite a few, we were never happy. It eventually dawned on us that what we wanted was something much too specific. We realised that we’d have to build our own boat completely from scratch.

There is a lot of information available on different hull materials – steel, wood, glassfibre, ferrocement – and on the pros and cons of each. Our boat was to be used specifically for cruising and we settled on aluminium as the material of choice for the following reasons:

• Minimum maintenance: I strongly believe that many boats are designed to look nice at boat shows without taking into account how the boat will have to be maintained for the next 30 years. Modern aluminium yachts are not painted on the topsides or on the inside, and osmosis does not exist. Steve and Linda Dashew describe how they used to be full of concern for the boat’s gelcoat when tropical traders came in canoes and dugouts to sell fresh fish, fruit or coconuts. But once they got an aluminium boat, concern melted away, and was replaced with nonchalant chat and friendly barter. This is what we wanted: ruggedness on the water – the marine equivalent of a Toyota Hilux (I have never seen a bow fender on an aluminium boat!). Lastly, the hull and deck are welded together, resulting in a very dry boat, which also lowers maintenance.
• A one-off: while GRP is good for mass production, it takes a lot of work to produce a single hull. Aluminium is perfect for a one-off, especially in our case, where the building and designing took place more or less simultaneously. It is the perfect material if you want to weld on, cut off, repair or adapt parts of your boat in future.
• Strong: aluminium and steel are the choices for those who want to go to high latitudes where things might go bump in the night. But aluminium is much lighter than steel, so there can be much more weight in the keel for a stiffer, safer boat.
• PEOPLE LOVE THEM: when we asked the owner of a big aluminium yacht at the Royal Cape Yacht Club whether he would care to show us his beauty, he was most welcoming in an unassuming way. We had lots of questions. I saw his two Rocna anchors and asked him if he was happy with them. “Well I should be,” he answered, “I designed them.”

It was Peter Smith, and after this first fortuitous encounter at the club he and Marlyse visited us at home on our project on several occasions with lots of valuable advice. He is not one to overstate or exaggerate, but when asked about materials his answer was simple: no material is perfect, but if he had to get another boat, if would be aluminium.

Peter should know – he has sailed to and explored Antarctica in his own boat more than once.

Welding technique was practised a lot. To check for strength, joints were tested in a vice to see if they could be broken.

MIG (Metal Inert Gas) welding: a wire electrode is fed through a welding gun to create an electric arc which melts the wire and pieces of metal to be joined. At the same time a shielding gas is fed over the arc to protect the weld from contaminants in the air.

The dream starts to become a reality as the first sections of hull are welded together

Drawbacks of aluminium

As Peter said, no material is perfect. The main disadvantage of aluminium is the possibility of galvanic corrosion. This can occur when another metal, like stainless steel, is connected to the hull, especially in a wet environment.

The way to prevent this is through a plastic gasket, special sealant or, even more common these days, by using a non-metallic alternative, for instance a plastic seacock rather than a stainless steel one.

Galvanic corrosion can also occur if there are stray currents flowing through a marina, especially if the underwater paintwork is not in good nick. To prevent this, aluminium boats carry sacrificial anodes on the hull. There should be enough of these and they should be checked and replaced as needed every few years. This is not a problem while cruising and anchoring away from commercial power.

I might mention that I have often heard the story of someone who dropped a metal coin in their aluminium boat, and then discovered it a short while later, just in time, before it has corroded straight through the hull.

I believe it’s total nonsense, or at least one of those urban myths that has become more and more fantastic as it has been retold over the years.

To be sure, we did the following experiment: six glass jars, each with a marine grade aluminium disc at the bottom, were filled, three with salt water and three with fresh water. We left the aluminium bare – as far as I know no one goes to the trouble of painting the insides of aluminium hulls. Into these we put samples of respectively stainless steel, lead and a variety of coins. After six months we examined all the samples, and only where the lead sample lay in salt water on the aluminium disc was there the slightest indication of pitting, less than 0.2mm in depth and diameter.

Herein lies an important lesson, namely that it’s often easier to test the validity of a statement than to go on hearsay or to get confused by contradictory theories found on the internet. So don’t hold back and be shy – test it, break it, burn it or freeze it – it’s great fun!

Economic sense

Lastly, we should mention something about the price of aluminium compared with other materials. The aluminium plates for our boat cost the equivalent of around £4,460, but to this has to be added the price of lots of consumables, as well as various bits of aluminium profile, so the total cost of the hull and deck was nearly double this amount, roughly £8,900.

It may seem tempting to build a boat out of steel or wood, with the cost of a hull and deck being less than two thirds of this price. But it is important to realise that, compared with the price of the whole project (around £41,600), this saving is less than 10%. To my mind it makes no sense to compromise on the hull material, for this would influence the character and the resale value of the boat for years to come. If money is to be saved, it can be done by having a simpler interior, internal systems, rigging or engine. These can always be upgraded later.

A learning experience

One of the most rewarding aspects of creating your own boat is learning skills you might not have acquired in any other way. Neither of us had ever welded before, so one of the first skills we had to learn was MIG (Metal Inert Gas) welding. For this we contacted the South African Institute of Welding in Johannesburg and organised to go on a week’s course.

The instructors there were surprisingly flexible in realising that, unlike most of their students, we were not seeking any form of certification, but rather a broad introduction to different aspects of welding from which we would be able to proceed through practising at home.

At the end of the week we were tired to the bone, but we were given a good nudge in the right direction, as well as lots of advice on what would and would not work for our ambitious project.

Back in Cape Town we bought a cheap MIG welder (which only pushes the welding wire from the machine’s side) and had the cable shortened (for less friction) instead of buying a more expensive push-pull machine. This worked very well and the wire hardly ever got jammed – probably because the wire used for welding marine-grade aluminium is quite stiff.

Then the fun started. We had lots of offcuts once we started cutting the hull plates, and it was on these we practised. We also watched lots of YouTube videos and then we practised some more.

We cut the welded metal up into strips and broke it in the vice. If it broke on the weld it was bad – if it broke on the heat affected zone next to the weld we were happy. The hierarchy of welds seems to be like this: a bad weld looks good but breaks easily; an average weld looks bad but is difficult to break; a good weld looks good and is difficult to break. I think I can safely say that our boat consists of equal amounts of the last two types!

Another skill was to learn how to use power tools. The wonder of working with aluminium is that common woodworking tools are perfectly sufficient: a circular saw (fitted with a blade for cutting aluminium, available from any hardware shop) goes through a metre of aluminium plate in less than two minutes. An angle grinder or pencil grinder fitted with a carbide tipped blade is perfect for removing the cold start of a welding run, but beware that an electric planer can destroy your project – and you if you’re not careful.

Just remember not to use abrasive discs or sandpaper where you want to weld again later – these will contaminate the area and lead to messy or weakened welds. And don’t forget to wear all that safety gear.

Is that a fair curve? Building boats by eye has never gone out of fashion

A place to build

There are those who believe that if you wish for something really hard, then you can attract it through some mysterious force. I’m not one of those people, but that’s more or less what happened anyway. One lunchtime at work, while gazing through our Sailing magazine, I found a curious advertisement: “Accommodation to let. Large loft on second floor of house in Milnerton, together with garden space suitable for building a yacht.”

This was still a year before we planned to move to Cape Town, but, as luck would have it, my best friend Paul Schutte was in Cape Town while finishing his own boat project. Paul happened to be looking for accommodation and he liked the place so much that he agreed to rent it for himself in the interim.

The owner of the house originally wanted to build his own yacht too, so he’d left space next to the house for his construction site. This is good, because, as with many things in life, you should have an exit strategy. It might be possible to build a boat in an enclosed space, but it’s very difficult to get it out again!

With wooden poles and beams covered with plastic tarpaulin and shade cloth, we built a 12m long lean-to next to the house (MIG welding requires a wind free environment). It was a lovely space so we threw a massive party for all our friends – and if you tell lots of people that you’re going to build a yacht in this big tent, then you have to do it!

How to Make a Sail

Last Updated: November 8, 2023

Ships and boats of all sizes have harnessed the power of wind for centuries. Sailing boats have continued to use sails to this day for recreational sports and hobbies. Whether you’re looking for a calm day on the water or to compete in a race, making your own sail can be a beneficial skill.

Getting Started

• Research the dimensions of similar sails and have an idea of what kind of sailing you’d like to do. This gives basic reference points to research and execute.

• If you are planning to sew the sail yourself, you will also need a special sewing table to be able to support the industrial sewing machine. This table needs to be about twice the size of a table tennis table in order to support the size of the sail.

• Shorter booms give you more maneuverability.

Designing the Sail

• The luff curve won’t match the curve of the mast. The top third of the luff curve will be slight and the bottom of the curve, close to the boom, will be greater than the mast curve. There are different theories on what the perfect luff curve should be so research how to optimize the luff curve for your prefered type of sailing.

• If you want more stability, add more battens; however, use less battens to make your boat easier to manoeuvre and more lightweight.

• Use heavier materials near the bottom of the sail. Seams also help to optimize the amount of material you use.

• Tape fabric or newspaper together for more surface area when creating a large sail.
• The luff curve and shaping the seam will create a three dimensional sail so don’t worry if your sail lies flat as you construct your pattern.

• Ensure that the material you choose resist stretching and can withstand rips.
• Heavy monofilm and woven sailcloth are common choices.

Assembling the Sail

• Stick and sew two panels at a time until the sail is all in one piece. You can now trim it to your design on the table and draw on the batten pockets.

• Create an adjustable head for your sleeve if this is your first attempt at a sail.
• Use pulleys from old sails or get them from a sail maker.

About This Article

To make a sail, first sketch the luff curve using your boom and mast measurements. Next, choose a scratch-resistant material that works best for your budget and sailing needs, such as Monofilm or Pentex taffeta scrim laminate. Then, place your pattern onto your material and outline the panel, battens, and seams. Once you have your sail’s shape, cut out the panels, and stitch them together, leaving extra cloth at the edges for seams.

It’s Time To Build Your Own Yacht

If you’re ever trying to rationalize a reason to build your own yacht,  look no further than your dreams. Think of the places you’ll go. The true beauty of a yacht, sometimes forgotten in her size and her solid feel and homelike surroundings, is that she is a conveyance, a mode of transport that can bring you and your family and friends to anywhere you could wish.

Build A Yacht For Your Lifestyle

Imagine spending the day exploring the meandering, shadowed streets of an old world town, having lunch at a sidewalk café, and showing your children or grandchildren the frescoes of a cathedral you learned about in a college art class (was it really that long ago?), returning to the yacht at dusk for dinner on board, and then an overnight passage, where you wake to discover an island laid out before you, with no other boats around, and a selection of snorkeling gear, standup paddleboards, kayaks, and more at your disposal. Only a yacht can deliver this kind of experience.

Yacht Building Is Your Ultimate Creation

But, why build your own yacht? It’s a good question. When you’re ready to make your mark on both the world and your life, there are few better ways to express oneself than through the creation of something wonderful. And, with a team of professionals dedicated to making your dreams a reality, and guide you through the steps of creating something real, and substantial, and beautiful, there’s no limit to what you can accomplish. To build your own yacht is to embrace your full understanding of the yin and yang of your personality.

New Yacht Construction Specialists

New yacht construction includes the technical specifications you lay out for performance and range, speed and hull volume, class and capability, all with the help of the yachting experts at Merle Wood & Associates who have extensive knowledge and new build experience. They have dedicated their careers to assisting their clients in creating something new and unique. Building a new luxury yacht can be a complex and costly event for someone unfamiliar with the process, which is why having a recognized global leader in megayacht construction on your team, before going to contact, ensures that the right elements are covered.

Custom Mega Yachts

Your custom yacht also comprises the beautiful spaces you will create and enjoy with your family and friends, replete with the welcoming social spaces that will offer unmatched vistas, embracing the sea breezes on the aft deck or from the flying bridge, gathering spots for the whole family that will provide the latest in media technology or a respite from it, as you prefer. How you want to divide your available space between stateroom and bath, closets and seating, galley and on-board gym, family and guests, it’s all up to you.

Build or Buy A Luxury Yacht

Of course, the creative process required to build your own yacht doesn’t happen overnight—and that’s part of the appeal, since the ultimate goal is meant to have an air of timelessness, of real creation, of getting it right. Often a candidate for a yacht-building project will instead buy a mega yacht, and this can be a simpler solution to one looking to step into a situation for the upcoming season. But similar to undertaking the effort to build your own yacht, the purchase process will be aided by dedicated professionals who will look to you for direction.

Luxury Yacht Ownership Awaits

Knowing one’s mind in terms of the required capabilities of the yacht and also the amenities desired will certainly help the process along and may in fact inspire you to consider building your own yacht, especially after one considers the available inventory on the market. After all, it all gets back to you and your dreams. And when you think of the places you’ll go, yacht ownership simply makes sense . The question is not, “ why buy a yacht ? ” The question is simply when and how. So whether you wish to know how to buy a yacht , build your own yacht or buy a mega yacht, the next step awaits.

Speak To A Yacht Broker

To build your own yacht, you’ll want expert guidance from qualified new yacht construction specialists. Merle Wood & Associates have seen the construction (including those now in progress) of more than 60 yachts ranging from 100 feet to more than 500 feet in length. Because of this, we are globally recognized by our piers and clients as leaders in new yacht construction.
