420 is a 13 ′ 9 ″ / 4.2 m monohull sailboat designed by Christian Maury and built by Rondar Raceboats, Fountaine Pajot, Snapir Sailing Craft Ltd., MacKay Boats Ltd., Lanaverre, Johnson Boat Works, Far East Boat Co., Whitecap Composites, Xtreme Sailing Products, and Nautivela starting in 1959.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

One of the most successful sailing dinghies ever. (Only the SUNFISH or LASER can be considered in the same league.) Originally designed and built by Lanaverre of France. (They built 32,000 according to one source.) Licenses were later granted to other builders around the world. In 1996, the International Class agreed to amend the deck layout. 1 Trapeze permitted. Spinnaker: 97 sq.ft. There is a ‘Club’ version of heavier construction and slightly different dimensions.

420 Class Association website:  http://www.420sailing.org/

The 420 is one of the best options to learn the ropes about two-person dinghy sailing. Crews learn how to tune a boat, set up control systems, trim sail combinations (jib, main and spinnaker together), work on downwind and upwind techniques, and importantly, learn how to work with another crew.

The Class has attracted many top sailors to it, providing a learning platform that has led them into successful Olympic campaigns and big boat careers.  

The 420’s design and class rules gave us the opportunity to build a boat similar to how the Mackay 470 is built in terms of the mould structure and look of the boat. 

The Mackay 420 hull shape was developed by naval architect Kevin Trotter. Kevin has designed very fast dinghies here in New Zealand over the years. Using the latest design and analysis software, along with the luxury of time we were able to evaluate the expected performance along with the look of the boat. 

Looking at where crews tended to sit in the boat in different conditions affected where we pushed the displacement curve of the boat.   Additionally, Kevin's skiff designs gave valuable insight into the way the rocker curve and buttocks lines should run through the middle and aft sections.

The hull is made from a polyester e-glass fibre, using foam core ribs and core mat panels.

The Mackay 420 deck to hull joint system is the same as our 470s, which allows for the same exceptionally strong but light gunwale arrangement. This extends around the bow and across the transom.

We have also borrowed some other features off the 470.  As an example, the way the mast partner is fitted to the deck after the boat is built allows the bulkhead in front of the mast to be more vertical and closer to the mast.  This is better for rig tension and weight distribution.  It also improves the look of the boat giving it a longer foredeck. 

The rudder stock is in cast aluminum which provides excellent support. The foils are built in the same way as our 470 foils by resin infusion.  

Most importantly the time and energy we put into the rudder and centreboard design along with the finishing of the moulds has resulted in some very special foils.

How to do a gelcoat repair.

Small gel coat repairs are relatively easy to do. 

What is Gelcoat made up of?

Gelcoat is a polyester product that is cured by using a catalyst called MEKP. (Methyl Ethyl Ketone Peroxide)

MEKP is a dangerous substance and should be treated as such when using, being very careful not to get any on your skin or in your eyes.

How can I get the catalyst - MERK?

We cannot ship MEKP so you will always need to buy it separately from your local marine store or fibreglass manufacturer.

How much MERK do I need?

The amount of Catalyst varies depending on the conditions you are using it in, but around 2%-3% will always work.

It is best to use a small syringe or dropper to get the required catalyst rate.

If you have mixed 100gm of gelcoat, then you are aiming for 2ml of catalyst.

What are the Gelcoat colours?

Gelcoats colours are not always a 100% perfect match.

Colour will vary depending on the depth of the repair and the batch.

470, 420, 29er & Starling are built from polyester resin.

For Polyester boats

470  White-  LS30    White PA 337

470  Grey- Grey RAL 7035

Blue = is supplier by Nuplex who have their own code which is not an international code

Does Mackay Boats supply gelcoat?

We supply a small tin (of each relevant colour) with each new boat.

Order additional gelcoat from our store, although it cannot be shipped by courier.

How do I do gelcoat repairs?

Doing gelcoat repairs is an art that improves with experience.

Making sure the surface is prepared well and keyed up is critical.

Overfill and then sanding back is a slow and time-consuming process.

Be very careful not to scratch the boat around the repair.

You shouldn’t sand the original surface around the repair with any paper coarser than 600grit.

Mask around the repair to protect the boat.

You can initially use a file or 150g to take the high parts off the filling, but don't use the coarse paper for too long or you will end up with scratches in the finished repair.

Once you have it fair with 600g, you can work your way through the sandpaper grades until you finish with 1500grit before cutting and polishing.

We would typically use 600g, then 800g or 1000g, then 1200g, then finally 1500g.

What can be customised?

Deck colour and non-skid on the side-decks. You can find these options if you try the boat configurator on our website.

What colour options do you offer?

White, Light Grey, Light Blue, Light Green, and Cream. On the 420, Grey is the most popular, with Blue and White equal second most popular.

4. Take Advantage of the Trapezoid: A 420 sailboat has a unique trapezoid-shaped sail, which gives it great performance in a wide range of wind conditions. Be sure to take advantage of this feature when youre sailing.

5. Balance the Boat: One of the main goals of sailing a 420 sailboat is to keep the boat balanced. Practice sailing with your weight evenly distributed across the boat, and move your weight to the windward side when tacking or gybing.

6. Use the Wind: A 420 sailboat is designed to take advantage of the wind, so be sure to use it to your advantage when sailing. Look for shifts in the wind and use them to your advantage when racing or just out for a leisurely sail.

7. Have Fun: Above all, dont forget to have fun! Sailing a 420 sailboat is a great way to enjoy the outdoors and spend time with friends. So, dont forget to enjoy it!

Final Thoughts

The 420 sailboat is an excellent choice for both recreational and competitive sailing.

With its lightweight and agile design, it is perfect for sailing in a variety of conditions.

It is also popular with college sailing programs, making it an ideal boat for aspiring sailors.

If you’re looking for a great boat for your sailing adventures, a 420 sailboat is a perfect choice.

Youth Sailors, Take Notice. Meet The New Turbo 420

February 7, 2013 by Sail1Design Editor Leave a Comment

Mildly resembling that mad scientist from  Back to the Future , both in action and in thought, Fran Charles continues to push our community, and sometimes drag others, toward sailing innovation. Because it is often very comfortable to get stuck in the past, using antiquated ideas, equipment, and rules, over and over again, it is important to guard against complacency, and to look forward to new innovation and progress. For several decades now, through the MIT Sailing Pavilion , Fran has done just that, tirelessly focusing on making sailing better, more accessible, and more fun, especially for those that are the future of our sport: young sailors. From carbon Techs, FJ innovations, colored boats & sails, team racing management, to Fireflies, Fran has kept the thought curve moving forward. This latest innovation, however, will launch this spring much further north, at Mount Desert Island in Maine, where Fran serves as the summertime sailing master. In what will surely be an exciting development for the youth sailing world, Sail 1 Design introduces you to youth/institutional sailing’s Flux Capacitor, the   Rondar Turbo 420 , a 420 hybrid that in its development assumed (almost) nothing, re-evaluated everything, employs very modern construction techniques. This platform promises to be a great deal of fun for kids. This boat is being developed now at the Rondar boatbuilding facility in Peabody, Massachusetts. Sail 1 Design  plans to cover, first hand, the first ever high school regatta held in Turbo 420’s. Stay tuned right here.

THE FUTURE, FINALLY

While change simply for change’s sake can be bad, what may be worse is never changing, and never adapting. All too often we read about where, how and why the sailing community is dwindling, that regatta participation is down, we read articles about “saving sailing”, and the like. Simply put, at the youth level, to attract kids, sailing has to be, well, fun . We risk irrelevancy if we don’t at least attempt to keep up with technology and innovation curves that usher in exciting developments to our game. Youth sailing today, along with institutional sailing, is certainly well-organized, well-meaning, and competitive, but could it be better? Could it be more fun? Does it need to be better and more fun than it is now? If you imagine youth & instituational sailing today, from Opti sailing up through club 420’s and Lasers, to high school and college regattas, what words come to mind? Is holding on to the Opti, the club 420, the FJ, to the Laser, the thing to do simply because they are the platforms we’ve been using for so long? Is it time fundamentally to change the game? What are other countries doing? What about college sailing; how many post-collegiate sailors pack it in after their senior spring, never to return? Many complain of permanent “burn-out” and droning, over mechanical sailing. Given the recent conversations about official equipment (see recent articles posted at the bottom of this piece), might the Turbo 420, or LaserPerformance ‘s “New Collegiate 420” help re-energize college sailing by virtue of being a vastly higher performing boat? A good test would be to interview those that sail the unique Tech dinghies and Fireflies at MIT, or those that sail the carbon-rigged Larks at Tufts. Do these boats make college sailing more interesting, and/or better?  We welcome your comments at the bottom of this article.

For now, if one had to constructively criticize the vast pool of youth sailing, or institutional sailing, what might one say? The boats we are using for major youth sailing, and for high school & college sailing development, to put it diplomatically, are, well, old, and somewhat bland. Some argue we are not adequately preparing the top-end sailors, while others argue we are not engaging everyone else. And while adult, contemporary, forward-looking one-design classes have exploded, and many feature very modern design concepts, from composite construction to exciting rig development, our one-design kids and school sailors still too often are sailing around in the same boats their parents, and even grandparents, were. Not a bad thing, necessarily; for example the Lightning class is still as strong today, if not stronger, than it was years and years ago, and there is nothing wrong with a great class and association, regardless of age. However, even old, established classes have updated their philosophy and class rules to acknowledge, if grudgingly, progress. Furthermore, other than the 29er (which is very difficult for intermediate-level kids to sail and not for light air at all) what real options do we provide, or better yet even encourage, our most important generation? If our goal is to develop a life-long passion and a love for sailing in our youth, we need to employ business concepts that work for any successful corporate institution: we need listen to our clients.  If participation is down, or stagnant, then what are our next-generation sailors saying about sailing, and how well are we responding to their ideas?

THE NEXT-GEN DINGHY CONCEPT

In comes the new Rondar Turbo 420. It will be interesting to compare this boat to the “New Collegiate 420” that is now built by the official college championship dinghy supplier, LaserPerformance. (Please see our earlier article on this new LaserPerformance collegiate 420). The “Turbo” features very modern vacuum-bag resin-infusion construction techniques, producing a very strong, very light hull (50-70 lbs lighter than a club 420 hull). The hulls are brightly colored for looks and for team racing. Hen ry (“you can have any color Model-T as long as it is black”) Ford is rolling over in his grave. Rondar boats has vast experience with high performance dinghy construction, so the job is in good hands.

The rig is modernized, updated, ergonomic, and simple. Unlike it’s sistership, the Turbo 420, among other things, has thoughtfully updated jib leads, floating spinnaker poles, and a newer slightly higher aspect sail design for the jib. In its first deployment, the Turbo 420 will fulfill the mission of the Mount Desert Island Sailing consortium, spearheaded by the Northeast Harbor Fleet, the MDI Community Sailing Center  &  Fran Charles, known as the “ Great Harbor Dream .” The plan is to keep all 21 boats in one central location during the summer months, so that all clubs can take part, share, and benefit from being together with these new high performance boats. It reads: 

“The mission of the Great Harbor Dream is to bring together Mount Desert Island’s youth 420 sailors. By rallying the various resources of local yacht clubs in one location for instruction, we will foster a compelling and fun teaching environment and create  beneficial learning opportunities through more competitive racing. Bringing our sailors together will potentially reduce the operating costs of our collective sailing programs, more effectively use the 420’s we own during peak seasonal demand, and inspire  and challenge our area youth by jointly promoting 420 sailing in the Great Harbor for generations to come.”

While teen social community building is the overall focus, the Turbo 420 is the real tangible key to making it happen on the water. Fran explains: “To further stimulate The Great Harbor Dream we made a decision to abandon the Club 420 Class boat and create a boat that would be more durable, much faster, safer by making changes to the rigging yet simple and easy to rig/de-rig.” These are not at all standard 420s but a hybrid which will be much more lively, fun, AND durable than any of the equipment on the market today. And, they cost virtually the same as club 420s.”

TAKING A CLOSER LOOK

SAILS – Sail designers from North Sails visited the builder to review the Turbo’s newly designated jib fairlead location. It is a bit further forward and inboard from the current position to get the cleat out of the sailors butt (crews, this is a welcome upgrade!) and to make it easier to release the jib sheet while tacking in big breeze. This will also eliminate the need for weather sheeting. The jib will be a bit longer on the leech, shorter on the foot and fuller hoist. This will simulate sheeting on a 470 or a 505 so the transition to higher performance dinghies will be more natural. Ample windows will be supplied on both sails. The sails will have out-of-the-box factory options for colored graphics and very large colored numbers on them. The mainsail will have the top two battens full length, a low-profile foam pad in the head to keep them from going turtle and a reef point for breezy conditions. Spins will be white and also offer a colored custom graphic (think: your club burgee or logo here).

North Sails Marblehead has done extensive rig analysis for the Turbo. Above, the Turbo rig model being run in 9 knots TWS. This extensive VPP modeling work was done to determine exactly where and how much to move inboard the jib fairleads, how that would affect main trim, and how best to set up the entire rig plan and sail shape. Pretty cool. These images are shown courtesy of North Sails, and lead designers on this project Doug Slocum & Will Welles.

FOILS – Cassette style heavy duty rudder head which remains bolted to back of boat. Rudder and centerboard will be epoxy cored, and very durable. Rudders to float. Centerboard to have both uphaul and downhaul lines and cleats. Hull will also feature recessed centerboard gaskets to alleviate gasket damage when boats are stored/dragged on their hulls.

RIGGING – The Turbo 420 spar will be approximately 6″ longer than current 420, however the hounds height will remain the same from  deck level. This will get boom higher and reduce head impact and likelihood of concussive head injuries. Spars will be Selden with the innovative gnav kicker system which pushes down instead of pulling down, a stainless-steel fixed gooseneck, 3mm sidestays, 2.5mm trap wires and quick release safety harnesses in a variety of sizes.

CONSTRUCTION – The Rondar Turbo 420, as mentioned earlier, will employ high-end construction techniques, separating it from virtually all other institutional youth sailing dinghies. The precision-oriented vacuum bag, resin-infusion system creates an extremely strong, very light product when finished. The whole process takes as little as 90 minutes. 

Above, the vacuum pump is humming and the vinylester resin is bled into the layup. Full saturation and nothing more. No air bubbles (voids). The whole saturation process takes about 20 minutes. Ki cks off hard in 90 minutes. All up weight of boats will probably be in the neighborhood of  185-190lbs. This is 50 lbs less than club 420 rule and 70 lbs less than most.

  Unless that guy is really, really strong, this boat is really light.

PUTTING IT IN PLAY

A collective effort of several Maine sailing clubs created the drive to purchase twenty-one new Turbo 420s. The goal is to rejuvenate youth sailing, retain and invigorate current sailors, and attract new up-and-coming sailors to the sport. The goal also is to promote a centralized, color-coded fleet for team racing, which encourages this up-and-coming part of the sport. Explains Fran, “In sailing, as in many sports, there is a dropout rate as the participants get into their teenage years. By creating a cohesive, centralized, team race-ready, exciting to sail fleet, the hope is that teens will stay with the sport a bit longer.” Time is ticking down to the launch of this new fleet. The first event scheduled is a high school regatta this spring, and then they’re off to their summer duty as a collective youth sailing fleet. Part of the logic of this boat, and future fleets they will assuredly inspire, is also to lend themselves well to team racing, which many young sailors love, and see as a fun alternative to racing around in long ovals in indistinguishable boats.  Will it catch on?

THE DINOSAURS HAD THEIR CHANCE

The Turbo 420 hybrid represents a bold, unapologetic embrace of next generation youth dinghy concepts, designed to continue to stimulate our young sailors not only to enjoy the sport but to stick with it. Some will see it as a threat to the establishment, and others may call for even more changes. To wit, why not make this Turbo 420 have an asymmetrical spinnaker with retractable pole? This is easier to rig and to sail, arguably a lot more fun, and clearly (just look at the J/70) the wave of our downwind future. Change is coming. Acknowledge, accept, debate, embrace, and then apply wisely, or risk obsolescence, or worse.

Our kids aren’t as impressed with our toys as we onc e were, especially in the rapidly changing landscape of the 21st century. You may not like it, but someday Google may well be driving all of our “cars”. There is an argument to be made that for the future of sailing, we need to learn to adapt our approach to our next generation to survive. Nothing lasts forever, and this boat moves us to that discussion.

Happy Sailing.

S.C.A.M.P. (Small Craft Advisor Magazine Project) For Plans Instant Download, click HERE Original Designer: John Welsford Additional Development: Kees Prins Kit Adaptations: Turn Point Design Our own youthful dreams often featured small boats in starring roles. Aboard these simple, stalwart little vessels we'd venture across nebulous bodies of water in search of distant wild shorelines or uncharted islands. We'd land, hike into the interior, and make camp. But always our boats offered refuge from any threat, including summer storms, which we'd wait out beneath our boom tents. At night we'd read sea stories by oil lantern and sleep under a blanket of stars.

Curiously, never once did these visions include negative images of wrestling with a heavy mast and complex rigging, fussing with a smelly, recalcitrant outboard, or being held off shore by our boat's draft. And even when we pictured the afternoon breeze kicking up whitecaps, never once did the vision include a chilly capsize.

It was the dream of returning to those simple pleasures that inspired thoughts of SCAMP. That and a persistent desire to go over "there" - that place we often see but are unable to reach. It seems to happen on every cruise. Never mind that we're usually sailing the smallest boat around for miles, we always come upon some ultra-shallow lagoon or serpentine tidal stream that disappears into the reeds, trees and rushes. To get in there - to really commune with nature - a boat needs to be light, shallow and easily propelled - and preferably flat-bottomed in case we decide to stay right though the ebb.

SCAMP features an offset centerboard, massive flotation from sealed seats and stowage cabin, a water ballast tank holding 173 pounds of water, an after cabin "veranda" that functions like a hard dodger, and a flat bottom and skegs for beaching.

PLANS: Complete plans now available on 7 24 x 36" sheets. A complete "Building guide" with suggested steps Is available in printed or digital format. Additionally, there are several boats beginning construction and documenting progress at the Small Craft Advisor message board and elsewhere online.

LOA - 11 ft 11 in Beam - 5 ft 4 in Draft (board up) - 7 in Water Balast - 173 lbs. Weight (including rig) - 420 lb s.
