How Tall Are Sailboat Masts? 9 Examples

The mast height of a sailboat varies with every model.

So what determines the height of a mast?

Here’s How Tall Sailboat Masts Are:

As a general rule of thumb, the height of a boat’s mast will be somewhere between 1.25 to 1.35 times the boat’s length, for an average of about 1.3 times the length overall (LOA) of the boat. An aspect of 2.5 or lower will be a low-aspect rig; above that is considered a high-aspect ratio.

Table of Contents

Understanding a Sailboat’s Mast and Rig

Sailboats are driven through the water by the power generated by their sails.

This is done using sail area. Sail area is calculated using the height of the mast and the length of the boom.

The battens, long strips of wood inserts in the sail, allow more sail area as they extend beyond a straight line from the head of the mast to the back of the boom, thus allowing more cloth to be carried.

Keep in mind that the mast height does not equal the luff length of the main; there is a distance between the deck and the top of the boom.

Most mains do not go all the way to the top of the boom mast.

Wind Gradient:

Designers are also aware of the wind gradient, meaning that as the wind blows over the water, the surface causes drag.

So the breeze is stronger the higher you get off of the surface.

Taller masts allow you to reach these stronger winds.

Mast Height:

While mast height is a prime determinant in the area, it is also possible to make a mast too tall so that the boat is always in danger of taking a knockdown.

Note there are some performance boats designed with masts that are too tall for the craft’s weight, assuming that the weight of the crew will balance out the sail area.

One thing to bear in mind here is a rig’s aspect ratio: this is determined by dividing the designed sail’s luff length by the length of the foot. An aspect of 2.5 or lower will be a low-aspect rig; above that is considered a high-aspect ratio.

Higher aspect boats perform better upwind; lower aspect ratios generally are more powerful in other wind conditions and are usually easier to control.

What’s the Average Height of Sailboat Masts?

Sailboats can range from 6 feet to a hundred or more feet in length if you throw out the multi-masted sailing ships of old.

The mast height for every single one is different.

The height of a mast is usually carefully calculated by figuring the amount of power needed to move a certain hull shape and weight through the water. In many cases, in the 1960s through the 1980s, some designers went by feel.

A few boatbuilders would use the same mast across several of their models to save money in some cases.

As a general rule of thumb, the height of a boat’s mast will be somewhere between 1.25 to 1.35 times the boat’s length, for an average of about 1.3 times the length overall (LOA) of the boat.

So, if you were going to average the mast heights of all 20-foot boats, you’d have about a 26-foot high mast and about 39 feet on 30-foot boats.

Boats built solely for cruising, particularly in offshore winds, will have shorter masts, and performance boats will have taller masts.

How do you Determine the Height of a Sailboat Mast?

Several factors determine a sailboat’s mast height.

A performance boat will have a higher aspect ratio for its sails and thus have a taller mast. Cruising boats will generally have smaller masts for the same length of the boat.

A wider and heavier boat than another boat will need more power to move it, so it will usually have a taller mast. If this heavy boat is a low-aspect-ratio rig designed for offshore work, it will probably have a comparably shorter mast for ease of handling in higher winds.

Conversely, a racing boat will be lighter but still have a taller mast to generate maximum power upwind.

Boats built for maximum performance will have very tall masts for their length and be very difficult to handle for an inexperienced crew – and sometimes for a trained, experienced crew as well, as the difficulties some of America’s Cup boats encounter demonstrate.

• The Melges 24 is a performance racer with a mast height of 31.4 feet for a head-to-head comparison. Her mainsail’s luff length is 28.92 feet, and the foot is 12.45 feet; she is a high-aspect-ratio boat.
• The Islander 24 has a mast height of 28.82, so it is 2 and 1/2 feet shorter than our Melges. The main’s luff length is 25.75 feet, and the foot is 11.52, for a low aspect ratio and much smaller main.
• The Islander 24 weighs 4,200 pounds, while the Melges 24 weighs less than 1,800 pounds.

How Tall is the Mast on a 40 ft Sailboat?

If a yawl or other rig with multiple masts, it will have shorter masts than a sloop.

If the boat is a fractional rig with a small foretriangle, like a modern high-aspect-ratio Hunter, the mast will be taller than another sloop of the same length:

• The old Tartan 40, an all-around great Sparkman & Stevens design from 1984, has a 51-foot mast. This is a classic racer/cruiser.
• The Nordic 40, designed around the same time, has a 52-foot mast.
• The Canadian-built C&C Crusader, designed in 1968, has a mast of 48 feet, but their later Mark 2 designs have masts of 53 to 55 feet in height.

These are all sloops. Ketch and yawl rigs will have masts shorter than this, as the smaller mizzens provide power (and helm balance).

So, this shows us that mast heights will fall into a range for any given length of the boat, again depending on other factors such as its function (primarily racing or cruising).

What is the Optimal Height of a Sailboat Mast?

As specified earlier, the designed height of a mast for any given sailboat generally falls between 1.25 and 1.35 times its length overall (as opposed to its waterline length).

The optimal height will be based on the designer’s calculations of the sail area and aspect ratio needed for the boat’s intended purpose. Beyond the simple racing/cruising divide, there are inshore and offshore cruisers and casual and serious racers.

Inshore cruising boats will generally be designed for maximum safety, and the mast height may be less than 1.25 times the length. Offshore cruisers may also be divided into casual and serious distance cruisers; a boat designed for better offshore cruising performance will have a taller mast.

It is unusual to find many cruising boats with a higher ratio than 1.3, however.

Racing boats will usually have a 1.35 ratio, though it can be as high as 1.5 or even higher at the extremes of the sport.

The mast height for America’s Cup AC50, a 50-foot catamaran, is 77 feet.

How Tall is the Tallest Sailboat Mast?

Two boats are currently competing for the title of having the world’s tallest mast.

Mirabella 5, now named M5 and launched in 2003, is the largest single-masted yacht ever built at 294 feet long.

Her mast is over 290 feet high.

The boom is nearly 90 feet in length. The mainsail has an area of 16,000 square feet! Her reacher (a large, light-weight genoa with some characteristics of a spinnaker), at 20,600 square feet, is the world’s largest sail.

The White Pearl, the world’s largest sailing yacht at nearly 350 feet, was launched in 2014. She has three carbon-fiber wing-style masts that are a little more than 90 meters high.

This puts the masts for the two yachts within a few feet of each other, though White Pearl gets the nod.

Sailboat Mast Height

You see this – what do you do? What should you have done?

Last week, Editor and Chief of Sail Magazine, Peter Nielsen, and I chartered a 38 foot catamaran from the local Moorings Base in the Bay of Islands, New Zealand, on a bareboat yacht charter. Peter was writing a story about sailing in the south pacific which will come out later this year (keep and eye out for it). We snapped some great shots, did some great sailing, caught lots of snapper and ate like kings in some of the most beautiful bays. The Kiwi weather really turned it on for us and the New Zealand Tourism board will be happy as Peter had a great time and surely will be writing up the Bay of Islands as a must see sail area.

So we sailed up into the Kerikeri inlet to the north of Moturoa island and past the stunning Black Rocks – where in the old days whales were so abundant here that whalers used to harpoon the whales from these rocks.  The wind was 20 knots out of the north so it made for a nice beam reach into the inlet. On the way back we decided to do a run through the Kent Passage. About 100 meters back I noticed power wires crossing from the mainland to Moturoa Island.

Kerikeri Inlet – Bay of Islands New Zealand

“Hmmmm”, I said to Peter “what do you think about those”.

“Hmmmm” replied Peter.

We both looked at the GPS which noted nothing on the electronic chart.

A quick consult of the paper chart showed the following image with a very hard to see thin line.

Not much information and no height datum.

“Hmmmm” we both said

We could now see a sign on the shore warning of the DANGER. But we could not read the specifics.

“Hmmmm” one more time. 30 meters to go!!!!!

With out any more hesitation and with prudence taking over, we brought the boat up into wind, turned on the engines and motored the boat away from the lines.

We got out the binoculars and were able to see the sign marking which indicated 23 above MHHW.

From the manual in the chart table, the sailboat mast height above the water line on a Leopard 38 is 19.1 m. That made it safe to proceed.

MHHW is the mean higher high water. This is the average height of the high tide during spring tides. Bridges and power wires are marked as such to indicate safe passage at these times. This is opposed to chart datum depths which are marked as MLLW.

So the lessons learned here:

• If you’re unsure of situations like this bail out. We did the right thing. Not that we were under any time constraint, but there is no time constraint that is worth really messing up like what could have happened.
• Know your sailboat mast height. When pilots get rated for an aircraft they spend hours and hours studying the characteristics of an aircraft. Yet when we go charter a boat – at best the Yacht Charter Base will spend maybe an hour with you.

Off the top of my head, here’s a list of boat characteristic specifications that you should know about when chartering a Sailboat on a Bareboat Yacht Charter sailing holiday .

• Sailboat mast height
• Offset of the depth meter (some charter companies add in a 5 ft offset below the keel, some do it at the keel, some do it at the water line and some don’t even know)
• Beam Width (for unfamiliar marinas)
• Number of water tanks
• Max cruising revs for engines
• Boat speed at max cruising revs
• Length of anchor rode
• Reefing wind speeds

Typically, you’re not going to be too concerned about fuel capacity with a week to 10 day long yacht charter, but it’s prudent to watch fuel usage.

There is a lot of other things to learn about a charter boat like locations of safety gear etc. But this is more about the boat dimensional characteristics.

I’ll end the post with a bit of humor.

Average Sailboat Mast Height

Last Updated by

Daniel Wade

August 30, 2022

‍ Sailboat masts are known to be quite tall, but how tall do they get? The answer varies on rig type, boat size, and design attributes.

Small sailboats, under 20 feet in length, rarely have masts taller than 20 ft or shorter than 8 ft. Sailboats between 20 and 30 feet have masts up to 30 feet tall, and large 40+ foot sailboats often have masts that exceed 50 feet in height.

In this article, we'll cover the average mast height of various sailboats based on length, and we'll also provide a typical height range. Additionally, we'll compare mast height by rig type. Finally, we'll cover the benefits and disadvantages of tall and short masts.

We sourced the information used in this article from sailboat design guides and the sailing community. Additionally, we analyzed several boats from each length category to determine average mast heights.

Table of contents

‍ Why are Mast Heights Different?

If you spend enough time around marinas, you'll undoubtedly notice the numerous masts that tower high above seemingly minuscule boats. Some are tall and thin, some are short and fat—and many are somewhere in between. So why do sailboat mast heights differ so much?

There are a lot of factors that contribute to mast height, not the least of which is boat size. Obviously, boats need a sail plan proportionate to their length, beam, and displacement in order to be efficient. The type of sail plan varies based on what the boat is used for.

Different rigs use different mast heights, even if the boat underneath is exactly the same. Let's assume we have two identical 30-foot boats. One has a tall mast and a triangular Bermuda rig, while another has a shorter mast with a four-sided rig.

The four-sided sail has a much greater area per foot of height than the triangular sail, so the mast doesn't need to be quite as high. Additionally, shorter masts can be thicker and stay within the same weight limits as a taller mast, so they can be thicker and stronger.

Average Mast Height by Sailboat Length

Now, we'll look at the average mast heights of sailboats by their overall length. We're not considering rig type beyond the fact that the majority of modern sailboats are Bermuda-rigged sloops—we'll get into that later. Here are some averages based on popular sailboats.

As you can see, the average mast height is highly dependent on the length of a sailboat. Most vessels have triangular rigs, which require a taller mast. It also seems as though mast height isn't usually far from the overall length of the boat, at least on tall single-masted vessels.

Why do Racing Sailboats Have Tall Masts?

Racing sailboats are known for their crazy mast heights and long, thin sails. There's a very simple reason for this, and it has to do with efficiency and drag. A taller and thinner sail is much more efficient for speed than a shorter and fatter sail. The same goes with the dimensions of the hull, as fast boats tend to be long and slender.

The science behind sail design is ancient and fascinating. In the 21st century, where the boat market values speed and agility, tall masts with thin triangular rigs are becoming increasingly popular. Short-masted vessels, once a key component of working offshore, are more durable but less common.

Average Mast Height of Multi-Masted Sailboats

Having multiple masts has distinct advantages, especially for cruising. Multi-masted sailboats are some of the best offshore cruisers ever built, and they are also remarkably durable. One of the main benefits of having multiple masts is that it adds a level of redundancy and increases your ability to finely control the vessel.

Multi-masted sailboats almost always have shorter and thicker masts when compared to similar single-masted vessels. Sailboats with four-sided mainsails, such as many classical schooners, are a particularly extreme example of this.

Gaff-rigged schooner masts are significantly shorter than triangular rig masts, sometimes more than 10 to 20% shorter. It's often the case that these vessels have a topmast that can be raised or lowered to add a triangular topsail, further increasing the area of the large four-sided sail plan.

What Sailboat Rigs Have Tall Masts?

Bermuda rigged sailboats (also known as Marconi rigged sailboats) are the most common tall-masted boats. Triangular rigs are tall because their sail area decreases as it moves up the sail, so they make up for it by adding height.

Fully-rigged ships also have very tall masts. These are the traditional sailing ships that are quite literally called 'tall ships' in the sailing community. They have multiple sails on each mast when fully deployed, and they usually have three or more masts and multiple headsails.

What Sailboat Rigs Have Short Masts?

The gaff rig is a common and classic sailboat rig that uses traditionally shorter masts. The gaff rig uses a square mainsail, which has more lateral area than a triangular mainsail. These vessels often deploy a topsail with or without a mast extension called a topmast.

The lateen rig is also famously simple and short-masted. It uses a triangular sail with spars that fly at an angle to the mast. It is an ancient sailing rig that was extremely common in the early days of civilization, and it served workboats across the world for centuries.

Are Shorter Masts Stronger?

Short masts can be stronger, but they aren't always. It depends on the design of the craft and is more dependent on rig type than the size of the mast itself. The strongest masts are found on gaff-rigged vessels. They are usually short and thick and traditionally made of wood.

The strength of the mast isn't so important when everything is working properly. It begins to matter in the event of a failure, like a broken stay.

A gaff-rigged vessel with a typical mast has a good chance of surviving a snapped stay as the mast can support itself. A Bermuda-rigged vessel, more likely than not, could lose its mast immediately after the standing rigging goes down.

What are Masts Made Of?

Masts are made of many different materials. Traditionally, wood was the mast material of choice. It was strong and lasted a very long time if maintained. Through the production sailboat era, when boatbuilders switched from wood to fiberglass for hulls, sailboat masts were mostly made of aluminum.

Today's high-tech racing sailboats have many more options to choose from. Composite materials, such as carbon fiber, are increasingly common due to their astounding strength-to-weight ratio. Alloy masts are also fairly common. Steel masts exist, but their use is usually confined to small sailboats and dinghies.

• Navigating the High Seas: A Comprehensive Guide to Sailboat Masts

Sailboat masts are the unsung heroes of the sailing world, silently supporting the sails and ensuring a smooth journey across the open waters. Whether you're a seasoned sailor or a novice, understanding the intricacies of sailboat masts is essential for a safe and enjoyable voyage. In this comprehensive guide, we will delve into the world of sailboat masts, discussing their types, maintenance, and everything in between.

Types of Sailboat Masts

Sailboat masts come in various configurations, each with its advantages and drawbacks. The two primary types are keel-stepped and deck-stepped masts.

Keel-Stepped Masts

Keel-stepped masts are the most common type, extending through the deck and resting on the boat's keel. They provide excellent stability and are suitable for larger sailboats. However, they require careful maintenance to prevent water intrusion into the boat's cabin.

Deck-Stepped Masts

Deck-stepped masts rest on the deck of the boat, making them easier to install and remove. They are commonly found on smaller sailboats and are more forgiving in terms of maintenance. However, they may offer slightly less stability than keel-stepped masts.

Components of a Sailboat Mast

To understand mast maintenance better, it's essential to know the various components of a sailboat mast. The key parts include the masthead, spreaders, shrouds, and halyard sheaves.

The masthead is the topmost section of the mast, where the halyards are attached to raise and lower the sails. It also often houses instruments such as wind indicators and lights.

Spreaders and Shrouds

Spreaders are horizontal supports attached to the mast to help maintain the proper angle of the shrouds (cables or rods that provide lateral support to the mast). Properly adjusted spreaders and shrouds are crucial for mast stability and sail performance.

Mast Materials: Choosing the Right One

Sailboat masts are typically constructed from three primary materials: aluminum, wood, and carbon fiber. Each material has its unique characteristics and is suited to different sailing preferences.

Aluminum Masts

Aluminum masts are lightweight, durable, and relatively easy to maintain. They are commonly used in modern sailboats due to their cost-effectiveness and longevity.

Wooden Masts

Wooden masts, while classic and beautiful, require more maintenance than other materials. They are best suited for traditional or vintage sailboats, where aesthetics outweigh convenience.

Carbon Fiber Masts

Carbon fiber masts are the pinnacle of mast technology. They are incredibly lightweight and strong, enhancing a sailboat's performance. However, they come at a premium price.

Mast Maintenance

Proper mast maintenance is essential for safety and longevity. Regular cleaning, inspection, and addressing minor issues promptly can prevent costly repairs down the line.

Cleaning and Inspection

Regularly clean your mast to remove salt, dirt, and grime. Inspect it for signs of corrosion, wear, or damage, paying close attention to the masthead, spreaders, and shrouds.

Common Repairs and Their Costs

Common mast repairs include fixing corroded areas, replacing damaged spreaders, or repairing shrouds. The cost of repairs can vary widely, depending on the extent of the damage and the materials used.

Extending the Lifespan of Your Mast

Taking steps to prevent damage is essential. Avoid over-tightening halyards, protect your mast from UV radiation, and keep an eye on corrosion-prone areas.

Stepping and Unstepping a Mast

Stepping and unstepping a mast is a crucial skill for any sailboat owner. This process involves removing or installing the mast on your boat. Here's a step-by-step guide for safe mast handling.

Step-by-Step Guide for Safe Mast Handling

• Gather the necessary tools and equipment.
• Disconnect all electrical and rigging connections.
• Use a crane or mast-stepping system to safely lower or raise the mast.
• Secure the mast in its proper place.
• Reconnect all electrical and rigging connections.

When and Why to Unstep a Mast

You may need to unstep your mast for various reasons, such as transporting your sailboat or performing extensive maintenance. It's crucial to follow the manufacturer's recommendations and ensure a safe unstepping process.

Sailboat Mast Boot: Protecting Your Mast

A mast boot is a simple yet effective way to protect your mast from water intrusion and damage caused by the elements. Here's what you need to know.

The Purpose of a Mast Boot

A mast boot is a flexible material that wraps around the mast at the deck level. It prevents water from entering the cabin through the mast opening, keeping your boat dry and comfortable.

Installing and Maintaining a Mast Boot

Installing a mast boot is a straightforward DIY task. Regularly inspect and replace it if you notice any signs of wear or damage.

Replacing a Sailboat Mast

Despite your best efforts in maintenance, there may come a time when you need to replace your sailboat mast. Here's what you should consider.

Signs That Your Mast Needs Replacement

Common signs include severe corrosion, structural damage, or fatigue cracks. If your mast is beyond repair, it's essential to invest in a replacement promptly.

The Cost of Mast Replacement

The cost of mast replacement can vary significantly depending on the type of mast, materials, and additional rigging needed. It's advisable to obtain multiple quotes from reputable marine professionals.

Yacht Masts: Sailing in Style

For those looking to take their sailing experience to the next level, upgrading to a yacht mast can be a game-changer.

Differences Between Sailboat and Yacht Masts

Yacht masts are typically taller and offer enhanced sail performance. They are often equipped with advanced rigging systems and technology for a more luxurious sailing experience.

Upgrading to a Yacht Mast

Consult with a marine professional to determine if upgrading to a yacht mast is feasible for your sailboat. It can be a significant investment but can transform your sailing adventures.

Sailboat Mast Steps: Climbing to the Top

Mast steps are handy additions to your mast, allowing easier access to perform maintenance or enjoy panoramic views. Here's how to use them safely.

Using Mast Steps Safely

Always use proper safety equipment when climbing mast steps. Make sure they are securely attached to the mast and regularly inspect them for wear or damage.

The Advantages of Mast Steps

Mast steps provide convenience and accessibility, making sailboat maintenance tasks more manageable. They also offer an elevated vantage point for breathtaking views while at anchor.

Mast Maintenance Tips for Beginners

If you're new to sailboat ownership, these mast maintenance tips will help you get started on the right foot.

Essential Care for First-Time Sailboat Owners

• Establish a regular maintenance schedule.
• Seek advice from experienced sailors.
• Invest in quality cleaning and maintenance products.

Preventing Common Mistakes

Avoid common pitfalls, such as neglecting inspections or using harsh cleaning agents that can damage your mast's finish.

Sailing with a Mast in Top Condition

A well-maintained mast contributes to a safer and more enjoyable sailing experience. It enhances your boat's performance and ensures you can rely on it in various weather conditions.

How a Well-Maintained Mast Improves Performance

A properly maintained mast helps maintain sail shape, reducing drag and improving speed. It also ensures that your rigging remains strong and secure.

Safety Considerations

Never compromise on safety. Regularly inspect your mast, rigging, and all associated components to prevent accidents while at sea.

Sailboat masts are the backbone of any sailing adventure, and understanding their intricacies is crucial for a successful voyage. From choosing the right mast material to proper maintenance and upgrading options, this guide has covered it all. By following these guidelines, you can sail the high seas with confidence, knowing that your mast is in top condition.

NAVIGATING the ICW’S Highs and LOWS

Several boats participating in the 2016 Sail to the Sun ICW rally found bridge heights to be more of a concern than the waterway’s notorious shoaling.

Brad and Terri Geddes were heading south with the Sail to the Sun ICW Rally in their Jeanneau 44DS, Reflections II. Leaving Hampton, Virginia, they were on the Intracoastal Waterway just past Norfolk along with 18 other boats. Things were going well until, with a sudden bang, their boat stopped dead in the water. Their mast had hit the Chesapeake Expressway bridge. But how? Why? The tide boards at the bridge showed the clearance to be 63 feet 5 inches, and their spar was less than that.

It turned out their mast height, which the yard had told them was 62 feet 6 inches, was actually 64 feet, and that didn’t count the Windex, transducers and VHF antenna, all of which added another foot. Fortunately, their gear wasn’t damaged, but Brad’s relaxed attitude was totaled. Their carefree trip now became a constant vigil for the next bridge, the challenge being to clear it safely. Low Bridges At any given sailing seminar, I typically get questions about depths and problem areas on the ICW and how to deal with them. That’s a valid concern, but boats of up to an 8-foot draft can handle the ICW without undue difficulty, provided they watch the tide. Just as an example, American Star, a 100-passenger cruise ship drawing 8 feet, runs the ICW regularly. Its two major routes are between Baltimore, Maryland, and Charleston, South Carolina; and Charleston and Jacksonville, Florida. Its secret? It plays the tides.

Really, these days, instead of depths being the problem, mast-height issues are currently a bigger challenge for ICW cruisers. In previous rallies, this had not been an issue. Of course, those events didn’t follow Hurricane Matthew, which hit the area in October 2016 and dumped immense quantities of water into the ICW, raising the water levels for weeks to follow. Even the lunar tides had an impact, with the full moon exacerbating the problem. Following Matthew, several areas of the ICW were closed for days as storm waters filled with debris poured into the waterway. Clearance heights of 62 and 63 feet were observed at the Socastee Bridge and other locations in South Carolina. These bridges are supposed to have 65-foot clearance at high tide. Southbound cruisers were trapped in marinas, unable to proceed until the waters receded.

More than a month after Matthew, and on much broader bodies of water, such as the Waccamaw River just north of Georgetown, South Carolina, problems persisted. The Lafayette bridge’s clearance was inadequate at high tide for three of the rally boats. They turned back to spend the night at a marina they had just passed to wait on the morning’s lower water.

VHF conversations between cruisers all along the ICW focused on observed bridge clearances. One woman assured us her spouse would climb the mast to determine the actual amount they cleared by, and radio the results back to the rest of the rally fleet. That suitably impressed us, and even more so when her report came in — they’d cleared with mere inches to spare.

The difficulties experienced were the result of the hurricane, of course, but the lesson is that conditions are always in flux along the ICW. Notwithstanding Matthew, there remain problems with bridge clearance in a number of locations along the waterway.

That’s because the foundations of several ICW highway bridges have sunk since being built. Engineers refer to this as soil compaction. According to a civil engineer I contacted, any bridge built on a sandy base will eventually sink to some extent. This is due to vibration caused by wind and vehicular traffic.

Vibration causes the soil beside and under the support columns to shift and move microscopically. Over time, the pilings shift lower. You can see this by wiggling your foot in the sand on a beach: Your foot starts to dig itself in. The same thing happens with a bridge piling, it just takes years before you see the results. This comports with my experience, as when I started cruising 15 years ago, I don’t recall any 64-foot bridges on the ICW.

One well-known problem bridge is Wilkerson Bridge, just north of Belhaven, North Carolina, at the south end of the Alligator-pungo Canal. This bridge has only 64 feet of clearance at high tide. To get by it safely, check out NOAA’S Hydrologic Prediction website (water.weather.gov/ahps2/ index.php?wfo=mhx).

One problem well-knownbridge is Wilkerson Bridge, just north of Belhaven, NC, which has only 64 feet of clearance at high tide. online charts are available all along the coast and give a graphical representation of the state of the tide at each tidal station. In Daytona, Florida, the southernmost bridge’s clearance rarely shows more than 64 feet, and there is less than 6 inches of tide. However, the bridge tide boards show what is termed “low steel,” which is the lowest clearance of the bridge at its outer edges. In the center of the bridge, there is 65 feet of clearance.

This was made clear to two of my 2015 rally participants, Chris and Fiona Cook, who felt they were trapped at this bridge by their mast height. After a two-hour wait with no discernible change, Chris spoke to a nearby marina manager who assured him he had adequate clearance. They then proceeded with no problems by staying in the middle of the channel.

Clearance Solutions

So how did Brad and Terri Geddes deal with their problem as they approached bridges with inadequate clearance for their Jeanneau 44DS? Returning to Atlantic Yacht Basin, in Great Bridge, Virginia, Brad headed up the rig, where he removed all the gear from the top of the mast and turned the VHF antenna upside down. This brought his clearance down to just his mast height of 64 feet.

This wasn’t quite enough for some bridges, however, so at the Pungo Ferry bridge, in North Carolina, they enlisted four husky college kids who were out fishing to sit at the end of their turned-out boom and on the rail of the boat. Two more men from the rally group took to bosun’s chairs hung from halyards. The resultant heel was enough to clear the bridge.

Farther south, one of the smaller rally boats took Brad’s halyard and heeled Reflections II over as they went through another low bridge. And at many bridges, Brad’s careful timing was such that he was able to simply pass through. Given that tides increase as you go south — to 9 feet in Georgia — the likelihood of coming to a bridge with inadequate clearance becomes much less. (In central Florida, however, where there are fewer inlets, tides on the ICW can be quite minimal.)

Bridges aren’t the only height issue, however. The power lines across the entrance to Boot Key Harbor in Marathon, Florida, are at 65 feet, as Brad and Sandy Fisher, rally participants on Doc’s Orders, discovered. They anchored outside and waited for low tide before entering.

Brad is now considering taking a hacksaw to his tootall fractional rig before going back north. He spoke with Fort Lauderdale-based rigger Paul Hite about shortening the mast by 2 feet. According to Hite, this is not as uncommon a solution to the problem as one might think. He has shortened several masts.

Paul grinds off the aluminum cap at the head of the mast, cuts the mast and roller furling to the desired length, reinstalls the furling, halyards and wiring, and welds the plate back on. Not counting the welder and any cutting required for the sails, it was a $3,000 fix for Brad, who’s quite content to pay that for the peace of mind he’ll get in exchange.

Other solutions to the bridge-height issue include removing the mast and shipping it south. This was the choice for Sail to the Sun ralliers Frank and Mary Grace Stitch on their Fountaine Pajot Helia 44 catamaran with its 72-foot mast. The ICW was a bucket-list trip, and removing the mast was the only way they could accomplish it.

You might be thinking, why not just go offshore and avoid the bridges? For some that’s fine, but not everyone wants to do a multi day offshore trip. At other times, weather issues make going offshore a bad choice, as anyone who has gotten caught out in a latefall norther can attest. And although it’s hard to believe for those asking, some people really do enjoy the ICW and all it has to offer. Tide boards showing 64 feet of clearance — or less — during high tide are not uncommon.

Given that tides increase as you go south, the likelihood of coming to a bridge with inadequate clearance becomes much less.

I know the mast on a catalina 22 is 25' but what is the height from waterline to top? I never had to worry about it before where I sailed but there is a bridge not to far from me that would shorten a trip for me. It's 32' haven't tried it doubt I will still just curious what if any clearance there would be.  

On our MK-II version, I need 33' clearance, but I have a VHF antenna on top of my mast) Don  

knew it was really close. Something inside me just knows that it will be that exact moment that I go under that a rogue wave will push me up a couple feet.  

There are a couple locations up and down Southern Calif. that I have pay attention to the tide status. But don't forget, all the different C-22 versions also have different mast lengths and overall mast heights. Don
