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.

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.

Did Bayesian superyacht’s 237ft mast cause it to sink?

B ayesian’s 237ft metal mast may have played a part in the sinking of the superyacht off the coast of Sicily , experts have suggested.

The yacht, named after the mathematical theory Mike Lynch used to make his millions in the tech industry, foundered in the small hours of Monday morning.

Key among potential reasons for the loss of the vessel will be its most striking feature – the aluminium mast.

Four British personnel from the Marine Accident Investigation Branch are on their way to Palermo to carry out a preliminary assessment.

There are also theories that hot overnight temperatures of 27C (80C) could have prompted passengers to leave portholes and windows open – hastening the sinking when the high winds hit.

Launched in 2008 by Perini Navi, Bayesian is one of the 50 largest sailing yachts in the world and her mammoth mast supported a total sail area of almost 32,000 sq ft.

Bayesian had the tallest aluminium mast in the world when it first took to the seas under her former name Salute. The record was overtaken last year when Jeff Bezos, the Amazon billionaire launched his yacht, Koru.

Koru’s masts stretch to 278ft tall according to Boat International magazine.

Tom Sharpe, a former Royal Navy commander and warship captain, said initial reports from survivors and witnesses suggested “that the weather was sufficiently violent to cause her to capsize at anchor”.

Weather reports from Palermo airport, 12 miles west of the yacht, suggest that at about 4am, winds switched from a gentle south-westerly breeze to gusts of 40mph, with temperatures dropping.

Local newspapers have described the weather as a tornado and a waterspout, which is a tornado above water.

The pressure of high winds on the mast could have helped tip the boat over in rough seas, experts have suggested.

Mr Sharpe said capsizing seemed “unlikely” to him given the Bayesian’s size “and that boats like that are designed to survive poor weather – unless something failed at the same time like a valve that let water in and made the whole boat unstable”.

He said it was more likely that the Bayesian had “dragged anchor”. Anchors are designed to lodge on rocks on the seabed, but if the seabed is too soft, or weather is so bad that the anchor is dislodged, then a boat can drag its anchor and drift.

If a boat drifts into an obstruction such as a rock or another boat, this can damage the boat by tearing a hole in its side leading to sinking, Mr Sharpe suggested.

The sea bed off Porticello, the Silician harbour nearest to where Bayesian was moored for the night, consists of a mixture of rocky and muddy areas, according to nautical charts reviewed by The Telegraph.

This means the yacht could have dragged anchor if it had been lowered into a soft, muddy patch of seabed.

A captain of another boat anchored nearby said his vessel was hit by abnormally strong winds on Monday morning.

Karsten Borner said the Sir Robert BP was battered by strong gusts in the early hours of the morning but he managed to stabilise the vessel while anchored by using the engine.

He said as they were doing this, they noticed the Bayesian nearby and manoeuvred to avoid hitting it.

“We managed to keep the ship in position, and after the storm was over, we noticed that the ship behind us was gone,” said Capt Borner.

Mr Sharpe said: “From a seamanship point of view, the other boat (Sir Robert BP) coming up on her main engines and using those to keep position around [her own] anchor is what you should do. Yacht anchors are often not that robust and that is the best way to avoid putting too much strain on it and/or dragging.”

An alternative theory is that the weight of the mast led the Bayesian to capsize.

A yacht industry source told The Times that the vessel sank after the weight of her mast took the hull beyond its “down-flooding angle” – the point at which a boat cannot right itself after swinging at a steep angle – meaning water rushed over the sides into the interior.

“The wind toppled the mast, which fell over the side, causing the boat to heel over and take on water, capsize and sink very quickly,” the source said.

This can occur whether the mast snapped off or not.

Sam Jefferson, editor of Sailing Today, told The Telegraph: “She has a very tall, aluminium mast – I believe it is the second tallest aluminium mast in the world – and that would not have helped.

“Many yachts with big masts have carbon masts instead of aluminium as these save on weight and improve stability and performance.

“Stability was obviously the problem in the extremely strong winds she was experiencing and I’d assume the boat was pinned on its side and could not right before it filled up with water.”

Another superyacht expert who asked not to be named told The Telegraph that the mast could have pulled the Bayesian over into capsizing, although he expressed some scepticism, saying sailing yachts are designed to prevent that from happening.

He said the anchor-dragging theory was also a plausible explanation for why the Bayesian sank.

Typically, crews try to anchor in safe spots that are sheltered away from the wind, they said.

The Bayesian was moored just off Porticello, a few miles east of Palermo. Prevailing winds from the north-east may have robbed the vessel of the shelter offered by the Sicilian coast, which lay to the west.

Dr Lynch was reportedly aboard the vessel. His wife, Angela Bacares, is among those rescued but six others, including four Britons, are still missing.

One person, reportedly the yacht’s chef, died in the incident and his body was recovered by rescuers.

The Bayesian’s last refit was in 2020.

The vessel was listed for rent for up to €195,000 (£166,000) a week, according to online charter websites.

The interior featured six cabins – one master, three doubles and two twin rooms – for up to a dozen guests, with the crew occupying separate quarters.

Fitted out in a Japanese style, the interior was styled by the Remi Tessler design house.

Under her former name Salute, the yacht won the Best Exterior prize at the World Superyacht Awards in 2009, and the Best Interior at the International Superyacht Society Awards in 2008.

A coastguard statement issued on Monday morning said the missing passengers were of “British, American and Canadian nationality”.

Camper & Nicholsons, managers of the Bayesian, confirmed the vessel sank at about 4.30am following “severe weather”.

The Italian Coast Guard is leading search and rescue operations, and said on Monday it had safely recovered 15 individuals.

Matthew’s Substack

Bayesian, the mega sailing yacht that sank last week by Sicily, was a disaster waiting to happen. Here's why.

Modern high-tech composite materials and rigging allow super-high single-masted sloops that were impossible to build in the old schooner era. An advantage of the old schooners was that with their sails down, there was much less windage far aloft. For a modern giant super-sloop, the windage aloft, even at anchor, is tremendous. All of those spreaders plus the mast surface area present a massive amount of windage when subjected to a blast of wind. The enormous height causes vastly more leverage than the same wind striking a "low aspect ratio" sailing rig. At anchor, deck hatches would be open. If the boat is heeled over far enough to put open side deck hatches underwater, down-flooding and sinking would happen in a matter of a minute or two.

To have a safe righting moment even after being knocked down with her mast horizontal and in the water, Bayesian would have needed a ballast keel 40 or so feet deep. This is not practical, so mega sailboats rely on inertia and mass to not get knocked all the way down. If they are knocked down, they are basically doomed if any hatches are open. There is no ballast keel sufficient to lever them back upright.

Bayesian had HUGE windage, and very high up. Even with her sails down and roller jibs furled, the 237' tall mast is (estimating from photos) almost five feet front to back, and she had 6 sets of "spreaders" that are almost the size of a Cessna's wings. Once she's heeled 45* by the sudden wind blast catching her on her beam, she didn't shed the wind, she caught even more on her spreaders. Her roller furling jibs are also massive, about a yard in diameter even when furled.

A sloop is the most efficient sailing rig in terms of potential lift to drag. 2 sails, one mast. But that enormous mast is always way, way up there. An old gaff schooner at anchor would present much less windage. But any giant sailing ship relying on mass and inertia to avoid being knocked down was and is always at risk. Another "safety factor" present in older sailing ships was that their organic-fiber sails and ropes would tend to "blow out" when struck by a wind blast, instead of taking the ship all the way over. Even being dismasted was preferable to being knocked down and sunk. With today's modern sails and rigging, the sails won't fail, and the sailing ship will be driven over on her beam end.

White Squall 1996 Trailer | Jeff Bridges This is a movie recounting when a sailing ship was knocked down by a "white squall" and sank in minutes with the loss of life.

This also happened to the 90' Pride of Baltimore #1, in 1986 under full sail on the Atlantic.

A schooner being knocked down in a storm also occurs in my new novel, Doomsday Reef. https://www.amazon.com/Doomsday-Reef-Matthew-Bracken/dp/0

THE BAYESIAN superyacht's own gigantic mast doomed the £14m boat when it was caught in a storm, an expert claims.

The luxury vessel had the tallest aluminium mast in the world which went a whopping 75m high.

Six people are still missing after the Bayesian sank early yesterday morning in a tornado off the coast of Sicily.

The single massive mast snapped in two, with glass smashing throughout the boat, and passengers fleeing for their lives as it capsized.

Celebrated British entrepreneur Mike Lynch , his daughter, and Morgan Stanley boss Jonathan Bloomer are among the missing.

Nautical architect expert Gino Ciriaci has now said the tall mast became a danger to the boat in the winds, he told Libero.

He said the tallest mast in the world "is also the most dangerous mast in the world because it catches the wind at a great height.

"If it had been a very low boat, perhaps things would have gone differently.

"But the Bayesian, precisely because of its mast... offered tremendous resistance to the wind.

Ciriaci also said that the rigging, the steel cables that move the sails, would also offer "enormous resistance".

He said that a strong wind hitting it from the side could cause it to capsize.

"It is not strange that a tornado managed to knock down the mast of the Bayesian.

 "Let's be honest, when there is a wind of that strength it also knocks down trees in the city. I see no blame or possibility of avoiding it".

The ship's captain James Calfield , 51, spoke from hospital yesterday and said had no idea the tornado was coming towards the ship.

"We didn't see it coming," he told  La Repubblica .

But the yacht's former stewardess said it is a "bit strange" that the ship sank in bad weather, having sailed through it before.

Monica Jensen, 48, said the vessel had faced bad weather "all over" including crossing the Atlantic., she told the Telegraph.

Jensen worked on the Bayesian from November 2018 to October 2020 for a private owner, and said it was then sold.

She was onboard for two Caribbean seasons and cruised around Italy, Malta, Greece, and the Balearics on the yacht.

The body of the boat's chef was found near the wreckage 50m under the water.

Furniture is now blocking the divers from being able to get into the bridge of the boat.

Luca Mercalli, president of the Italian Meteorological Society, said 200kmh winds could be felt over Sunday through Monday.

He described the weather as: “A so-called funnel cloud forms, generating winds of up to 200kmh which can create a water spout at sea by sucking water into the air.

“The event can be restricted to a few hundred metres and be over in ten minutes."

Waterspouts form when warm air from the surface of the water mixes with cold air from higher in the atmosphere.

When they mix it creates a vortex that picks up water from the sea and spins it at up to 80kph.

On average they last about five to ten minutes with the largest being able to grow to a hundred metres wide.

WHO WERE THE PASSENGERS?

In a bizarre twist of fate, it was revealed yesterday that Lynch's ex-colleague and fraud trial co-defendant  Stephen Chamberlain died days before  the yacht tragedy.

The majority of passengers were understood to be from the UK.

Citizens from New Zealand, Myanmar, Sri Lanka, Ireland, Canada, the US and two dual British-French nationals were also on board.

Who are the six still missing from the Bayesian yacht tragedy?

By Ellie Doughty, Foreign News Reporter

THE BAYESIAN superyacht was hosting a lavish party for 12 guests, with 10 crew also onboard.

After 15 people were rescued from the water on Monday, six people remain missing and one has been found dead.

Italian authorities said the man recovered near the yacht wreckage was the chef working onboard.

Four of the missing are British and two are American.

Mike Lynch, 59, and his daughter Hannah, 18, are among the four Brits lost at sea.

International chairman of bank giant Morgan Stanley, Brit Jonathan Bloomer, 70, is also missing along with his wife Judy.

As is top New York lawyer Chris Morvillo, a solicitor at major firm Clifford Chance who worked for Mike Lynch, and his wife Neda.

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.

Upon a small crack was found at the mast and the rig was replaced. The lesson?

How much mast height should be maximum / minimum meters Discussion in ' Sailboats ' started by mr.sailor , Nov 6, 2015 . mr.sailor New Member First of all,I'm sorry for my bad english. I have a 7.5 m. length 2.15. width and ,1.2 m. deep. And the backbone keel wooden sailing. How much mast height should be maximum / minimum meters.because,it's mast 8m.   gggGuest ... Its a bit like asking how big an engine should there be in your car. There isn't really a right answer. If you can provide a lot more detail on what the boat is like and what you want to use it for then it may be possible to narrow things down a bit. 8m mast on a 7.5m boat doesn't sound unusual though.   PAR Yacht Designer/Builder Welcome to the forum. Agreed, an 8m mast on a 7.5m boat isn't uncommon. For example the Hunter 25 (which I have in the yard at the moment) is 7.57m long, 2.44m in beam, with a 6.15 LWL, draws 1.19m and it's P dimension is 7.56m and it's I dimension is 9.14. The mast height is about 8m.   Petros Senior Member a larger mast will give it more sail area, and more heel when under way. So a deeper keel or more ballast will be required, which means more force on the hull, so a stronger hull is required (adding more weight). More sail area allows you make better headway in light wind, but means you will be reefing the sail sooner. It also means more weight aloft, adding to the heeling. It is a complex trade off, you can have mast lengths of as much as 1.5 times the boat length, or you can have them as short as about .6 or .7 the Length over all. A lot depends on the intened use of the boat, the desired performance, and the type of material it is made from (wood, vs. fiberglass, vs. carbon fiber composite). what is the intended use of the boat? is it a modern cruiser, or performance design, racer or what?. Or is it a traditional design?   Stephen Ditmore Senior Member Estimate desired angle of heel (maximum upwind before reefing). Estimate righting moment at that angle of heel. Assume a sail loading of one pound per square foot of sail. The sail area and heeling arm (height of center of effort above center of lateral resistance) should be that at which heeling moment = righting moment. I might return and convert to metric, but not tonight. If someone else wants to, please be my guest. Assumed sail loading should be higher for multihulls.   Advertisement: Joakim Senior Member PAR said: ↑ Welcome to the forum. Agreed, an 8m mast on a 7.5m boat isn't uncommon.

A taller mast can only help in wind speeds low enough that you are still looking for more power (below hull speed in non-reefing conditions) and the extra drag makes it harder to reach that point.
