Diam 24: The Fastest-Growing One-Design Fleet in St. Maarten

• By Herb McCormick
• August 1, 2024

It was the opening day of racing last February in the sixth annual Caribbean Multihull Challenge and Rally on the island of St. Maarten, and I was in the thick of the action aboard a 50-foot French catamaran charging upwind. At least I thought I was. A fleet of diminutive but extremely quick trimarans started to pass us, their three-person crews adorned in helmets with the spray flying. It sort of reminded me of the classic Western film Butch Cassidy and the Sundance Kid, where the protagonists are chased by a relentless posse and Butch asks Sundance, again and again, “Who are those guys?”

At the CMC, it turned out those dudes were sailing the fastest-growing one-design fleet in the islands, a nimble, blazingly quick 24-foot tri called a Diam 24. And man, they were having a blast. In an era when participation in sailboat racing is on the wane in many venues, the Diam 24 class on St. Maarten is an unqualified success story.

Built in France with infused fiberglass and a carbon-fiber core to a design by the VPLP naval architecture group—a consortium known for massive offshore trimarans such as the MOD 70—the Diam 24 is a small wonder that can be dismantled and shipped easily in a specially designed container. But the class owes its resounding popularity in St. Maarten to a singular, speed-obsessed French sailor named Pierre Altier, who skippers his own Diam 24 called Cry Baby.

After his first sail aboard the boat three years ago, Altier says: “I fell in love with this boat. Everyone says multihulls don’t go upwind that well, but the Diam points at a 45-degree angle at a speed of 14 knots, which is crazy for a boat this size.” In late 2021, Altier purchased Cry Baby and persuaded a couple of friends to join the fun, and all three boats were shipped to St. Maarten in a single container. The roots of success were planted.

But Altier, who runs a charter business in the islands, wanted more competition. He began lending the boat to friends and other local businesses to show them what it could do. “That was the key to get more people to join us,” he says. Before long, there were five Diams on the starting line for local events.

But Altier still wasn’t satisfied. He realized the numbers would grow if he owned several boats himself and chartered them out for regattas at reasonable rates, which is how the fleet grew to the 10 Diams racing in the CMC. At $700 a day for racing events, each of Altier’s three Diams is a bargain. Running rigging and a dolly for beach launching is $69,000 for a brand-new Diam with North Sails, which includes shipping to St. Maarten. In small-boat racing, it’s hard to imagine more bounce for the buck.

For Altier, there’s been only one drawback: For the first couple of years, nobody could touch Cry Baby on the racetrack. That’s no longer the case, as his fourth-place finish in the most recent CMC attests. “The competition has definitely ramped up,” he says. “I have a harder time than before to try and win. Better and better sailors were welcomed to come try and beat me, which is what happened.

“The word is getting out about how good the class is,” he adds. “And now we have multihull sailors from other classes coming to try out the Diam. It raises the level for everyone. For example, if you tune the boat better, we’re finding you can be 3 or 4 knots faster. It’s incredible. It’s been a real game-changer. And I’m very happy that the game is changing.”

So, Cry Baby is no longer the undisputed Diam 24 champion. Altier is spilling no tears.

Diam 24 One Design

An international class of one-design sailing boats which allows you to experience multihull racing for €50,000. VPLP gave the Diam 24 an extremely competitive hull design , eliminating the unnecessary wherever possible.

This trimaran has all the characteristics of a machine designed for speed and absolute pleasure , with high beams, aggressive floats as long as the main hull, a glass and carbon fibre core construction using the infusion method, a very rigid structure and rudders on the floats.

Easy to dismantle and transport, the Diam 24 OD has been the chosen class of the Tour de France à la voile since 2015, attracting famous ocean-racing skippers and inshore specialists to this race linking the English Channel to the French Riviera.

A multihull for the French classic the Tour Voile? Meet the Diam 24, a VPLP-designed 24ft trimaran

• April 15, 2015

Organisers of the Tour de France à la Voile hope to revitalise the team event by revamping the format and choosing a 24ft trimaran. James Boyd takes a close look at the boat

Boat is trailable

The boat is trailable and at the inaugural Marseille One Design event the two Diam 24s competing turned up neatly stowed on one trailer – something that will no doubt please the Tour Voile’s organisers.

While the three hulls are built using resin infusion in glass with a foam core, the rest of the boat is glassfibre, but with uni-directional carbon fibre reinforcement. This includes the two crossbeams, which should improve the trimaran’s longitudinal and diagonal rigidity. The foils have been upgraded over the Multi 23 and gone is the kick-up centreboard, to be replaced by a longer daggerboard and the single rudder in the main hull has been replaced by twin rudders – one in each float.

Lauriot Prévost explains: “Having two rudders, you can fly a hull [the main hull] and maintain good balance on the helm. The swinging daggerboard made sense in terms of grounding, but having one big daggerboard allows a more efficient blade.”

The tri can fit into a container for trailing

The boat certainly looks the part. With its heavily raked rig, low freeboard and its reverse dreadnought bows, it resembles a mini Banque Populaire or MOD70.

A significant element to trimaran design is to prevent pitchpoling and before foils were introduced to the floats to alleviate this, trimaran bows typically had maximum volume to keep them buoyant. However, according to Lauriot Prévost, the philosophy has now changed and the wave-piercing ability of the Diam 24’s sharp bows, combined with a V-section deck, means the boat doesn’t decelerate as much when encountering waves.

Low profile

To reduce weight, the main hull is low-profile, providing just enough freeboard for adequate clearance between the crossbeams and the sea. Its underwater shape is flat, terminating in a transom wide enough to mount an electric engine.

The floats have reasonably high volume, making them quite powerful, but Laurent Prévost explains this is necessary because, unlike most of the larger racing trimarans his company has designed over the past 20 years or so, there are no foils in the floats to provide vertical lift (these were deemed too expensive).

An exhilarating ride for a crew of three for a reasonable budget

In addition, to give the boat a ‘racy look’, the severe 7-8° of mast rake has significant seakeeping functions, helping to lift the bows out of the water and improving the balance of the boat and its longitudinal stability when sailing, says Lauriot Prévost. As with most racing multihulls, the sail plan is simple, comprising just three sails: a square-topped main, small blade jib and a furling gennaker.

Exhilarating ride

The Diam 24 is not a state-of-the-art foiling multihull like the GC32, but, like the J/80, can provide an exhilarating ride for a crew of just three for a reasonable budget. The boat is capable of speeds into the mid-20s and, at around 500kg, is light enough to fly the main hull in just over ten knots of wind (with the crew on the centre hull rather than up to windward).

Apart from the Tour Voile, the Diam 24 already has a six-event circuit and its own class at events such as the Grand Prix Guyader. Diam 24-only events were held last year in La Trinité- sur-Mer, Lorient and, of course, Port la Fôret.

Clearly the boat has struck a chord. Since the first Diam 24 was launched in the spring of 2013 examples have been acquired by leading sailors, including Vendée Globe skippers Bernard Stamm, François Gabart and Vincent Riou, as well as Loic Féquet, skipper of the Multi 50 trimaran Maitre Jacques , and Commodores’ Cup winner Géry Trentesaux.

At the time of writing 31 teams had signed up for the 2015 Tour, which takes place on 3-26 July and starts in Dunkirk.

The Caribbean’s Hot One-Design Fleet

• By Dave Reed
• August 13, 2024

I’d love to look around and enjoy the scenery, but I can’t take my eyes off the leeward bow that’s slicing through the Caribbean at 20 knots. I’d been advised earlier: The fine line between full-tilt and pitchpole is somewhere right around the chine on the wave-piercing bow. The warning also came with a caveat: “The faster we go, the safer we go.”

That’s the wisdom of Pierre Altiere, a master of the Diam 24 trimaran, with whom I’ve scored a ride for the St. Maarten Heineken Regatta. The point of the exercise is to experience firsthand the hottest one-design fleet in the Caribbean. Altiere’s boat is named Cry Baby , which I may eventually come to understand, but right here, right now, all I can think about is the gust breathing down my neck.

I ease the gennaker sheet in my hand and watch the bow submerge. Oh, sh-t, I think. Here we go. I’ve seen pictures of Diams tumbleweeding, but the bow porpoises. A ball of seawater smacks the forward beam and explodes into a cloud of sunlight sparkles and foam.

With a jab of the tiller bar, Altiere redirects the boat and reloads the sails. The daggerboard hums a few octaves higher as we skim across the shallow blue flats of Phillipsburg Bay. It’s thrilling and a little terrifying, and thankfully, we’re just getting started.

It’s an early March morning on St. Maarten’s Kim Sha Beach, on the bustling Dutch coast where six identical 24-foot trimarans sit under palm trees, surrounded by umbrellas, chaise lounges and rental kayaks. Four other Diams swing on their anchors a doggie-paddle’s distance from the beach. This is the homegrown Diam 24 One Design fleet, which in a few short years has multiplied from three to 10. Soon enough, Altiere promises, if his Diam dream scheme pans out, we will be looking at as many as 20.

Altiere, I’m told, is the spark, the one who started it all, and judging by the parade of sailors seeking him out for advice, parts, assistance and you name it, it’s obvious that not much happens without Altiere. As we rig our own boat, interrupted by phone calls and favors, he gives me a quick lowdown on the Diam, which was created by Vianney Ancelin, a French multihull sailor and boatbuilder. Ancelin’s vision was a recreational multihull that average sailors could handle—sporty but not lethal, high-tech but not overpriced. That was the idea before the Tour de France a Voile—a multistage regatta—adopted the Diam as its official one-design. Pro race teams with million-dollar budgets promptly priced amateurs out the class, and then the pandemic put a fork in the Tour. The builder, ADH Inotec, stopped production at just north of 100 boats. With the Tour on hold, however, there was suddenly a pile of secondhand race-ready boats, many with containers full of unused spares, most fetching $20,000 to $30,000.

Enter Altiere, the tall, jovial and hard-charging Frenchman who taught at a sailing school as a young man and then opened his own in Tahiti before landing in St. Maarten, where he operates a thriving private catamaran charter business. As a top-level F18 catamaran sailor not far back in the day, a friend once invited him to race a Diam in France. He knew little to nothing about the boat at the time. “As an F18 sailor, I knew what I was doing,” he says. “I hadn’t raced [in Brittany] in 20 years, but we somehow made it onto the podium, everyone applauded us, and I enjoyed it so much that the next day we started talking about becoming an agent for North America.”

He did, but the big continent was impossible to crack, so he pivoted to a better plan: bring potential buyers to the boat and give them a taste. Step 1: Establish a Diam base at home in St. Maarten and show off the boats. Step 2: Enter them into the region’s big-draw regattas: the Heineken and Les Voiles de St. Barth.

“There’s nothing better than an easy flight to St. Maarten, throwing your bag in the hotel, and jumping onto a Diam that same day,” Altiere says. “Just like me, I was offered a chance, I had a great experience, and right after that, I bought a boat. That’s the easy-regatta concept here: Fly in, race, celebrate, fly out.”

And that’s how “sort-of” New Yorker Adam Holmes and his buddies Ben Ferraro and Bob Young were lured to Kim Sha in late March for the Heineken Regatta. Holmes, an advertising executive and Long Island-based racing sailor, had heard about the Diam fleet through a friend in St. Maarten, who connected him with Altiere, who had one charter boat available for the Heineken Regatta.

How much for a good time?

Five-grand—tops—according to Holmes’ mental math, and that was with a top-shelf condo, on the water, for a week. Altiere’s charter fee, which included four days of racing and two days of practice, was only $3,700—worth every penny on the speed-to-dollar scale. For months, the three of them exchanged Diam sailing videos that they found online. “That was like the start of the adrenaline rush,” Young says, and when they jumped on board for their first figure-it-out-yourself session in St. Maarten, the real thing was a real rush.

“We didn’t get a very detailed briefing before our first sail,” Holmes says. “At one point on the first practice day, we were sending it at like 19 knots, and the hull was so far underwater. Bob had the kite strapped in hard and we were just flying…like really, really on the edge. The Diam guys following us in the RIB and yelling at us in French were freaking out because we hadn’t yet signed any paperwork.”

“At the time,” Ferraro adds with a laugh, “we had no idea we were on the edge—we didn’t know any better.”

But with a few more hours of practice and less than 30 minutes of one-on-one with Altiere, they were ready enough to throw themselves straight into the races. Ferraro was nominated to drive, Holmes got the back-breaking main trimmer’s spot, and Young took on the busy end at the front of the cockpit. 

On the first morning, the breeze is up to 15 knots, and even though the start is in 90 minutes, the vibe on Kim Sha is bizarrely relaxed. Beach attendants rake the sand for the inbound tourists while sailors wander about in farmer-john wetsuits, surf trunks and rash guards, most of them conversing in fast-paced French and tinkering with their boats.

Among them is Erick Clement, one of the originals. He is a master of the Caribbean multihull racing scene and enjoying his retirement from F18 catamaran racing. Daily yoga, and healthy eating keep him young and in Diam-worthy shape.

“The speed is good and the boat is not complicated, but you have to get a feeling for it,” he tells me in his best broken English. “When everything is right, the steering is balanced perfectly, and you listen for the noise of the daggerboard—that helps you know when it is right.”

As a simple three-crew boat, the roles are straightforward. Whoever has the pleasure of helm also gets the traveler—the capsize preventer. The middle crew manhandles the insanely loaded mainsheet, trims the gennaker, and assists with dousing it. The forward crew is responsible for the self-tacking jib sheet, sail controls (outhaul, cunningham, mast rotator), gennaker hoisting and the daggerboard. Between calling tactics and jibing angles, housekeeping the trampoline, and watching for traffic, it’s an active boat for all involved, especially when big-breeze buoy racing in St. Maarten.

“All crew are super-important,” Clement adds. “If one is not playing the game, you can’t do anything. You have to have a good balance with each other.”

That will be a problem for us on Altiere’s Cry Baby because we are rotating new teammates every day. With us for the first day is a strapping young Frenchman named Corentin, who goes by Coco. He’s one of Altiere’s charter boat captains and has some Diam racing experience, which is good because we’re straight into the first start without a lick of practice. It’s a chaotic five minutes of weaving through rush-hour traffic: big custom raceboats, cruisers, bareboats and two 100-footers, all pinging the starting line.

The Diam will go from zero to 15 rapidly, but it’s not the kind of boat you can luff-and-hover on the start. Full speed is Altiere’s preferred approach, and with 45 seconds remaining in the opening sequence, he is stalking next to the committee boat, mentally calculating the layline and time to kill. But the other boats are stacking up at the starboard end, making what looks to be an impossible entry. But, hey, Altiere is the man and the defending champ. This is his domain. Who am I to doubt?

At 30 seconds, he booms, “OK. We go!”

And go we do, bearing away to full hum, straight toward the big catamaran committee boat. Just when it looks like he is going to pull off a high-speed barging start, Holmes and his crew tack in front of us and stuff the boat into irons—three sun-creamed deer in our headlights.

It’s either them or the committee boat, but Altiere pulls the hand break, and we coast to a near stop. The bow of our center hull disappears beneath the catamaran’s bridge deck, and the starboard bow just clears the cat’s starboard transom. I run forward and push off, and Altiere apologizes while cursing the New Yorkers for their erratic driving.

“I mean…it was our first race, and we were still trying to figure out how to tack the damn thing,” Young says. “That was a little nutty.”

“OK, let’s go,” Altiere shouts once again. More trim!” And with that, we’re chasing down the fleet. I pull the mainsheet as hard as I humanly can. The sail is board-flat and the telltales are streaming.

“More trim!” he shouts again. “We do it together.”

He reaches forward with his big right arm, grabs hold of the sheet with one hand, and together we grunt another 2 feet. The weather hull rises higher, and then the center hull breaks the surface. I’m staring at the line that Altiere had drawn on the bow with a Sharpie. That’s my fine-line guide for the week.

“More speed,” he says. “We will get them.”

I pull but get only another inch. He reaches in and gets another 6, finds his gear, and lets it rip.

The collective opinion on Kim Sha is that Altiere is the best sailor in the fleet, and I can see why. He effortlessly threads the trimaran around oncoming traffic, across big waves, and through giant puffs that pin other boats on their ear. He will dive to leeward of another boat and sail right through its lee. Downwind, he sits inside the center hull, hunched, with his hand behind him on the tiller bar, laser-focused. He senses every subtlety of the boat and knows what it will do before it does it. And more than once, when we sail into a lull and our speed drops, he puts his hand up in the air and says, “Bwaah…come on, wind, what is wrong with you?”

He’s seriously annoyed with the breeze for denying him his speed.

The first race is a windward/leeward blur, and we somehow manage a midfleet finish. Same for the others that follow, but our mishaps reflect our thrown-togetherness. We’re fast in a straight line thanks to Altiere’s skills, but every slip-up is a dozen boatlengths lost—and that’s no lie.

Back on Kim Sha, there’s a beach bar 10 feet from the boats. It’s got reggae, cold beer and cheeseburgers in paradise. The fellas from New York are happy to be back on the beach with their recovery juices in hand.

“That was kind of devastating,” Ferraro says. “We were miles behind on all the races, like it was not even close. We weren’t going to drink, but then all of sudden, we’re standing there with a drink in our hand and were like, ‘What just happened?’”

Young isn’t bothered at all about the results. He’s whipped, but it’s worth it: “All I remember was thinking, I’ve never gone that fast on a sailboat. I think our top speed was 20.7. The sound of the boat and that hum going at that speed was just like, holy sh-t. Let’s just hold on.”

With the wind forecast to peak into the mid-20s, the St. Maarten Heineken Regatta’s legendary around-the-island race is next on the to-do list. Big island, big breeze and it’ll be big-time fun, Altiere promises me when we meet at the beach and introduces me to Camille, another of his charter boat captains. She’s petite, and Altiere confesses he had miscalculated the wind forecast when lining up crew for the regatta.

“We will struggle a bit upwind because weight is very important,” he says, slapping a big hand on my shoulder and cracking a big smile. “But we will be very, very fast on the reaches.”

And he isn’t kidding.

To start our circumnavigation, the race committee dispatches us on a short upwind leg. Once we turn downwind and deploy the gennaker, we’ve got many miles of open-ocean high-speed tropical send. In these conditions, Altiere is in his element and sails right up to and past boats that got ahead of us on the upwind leg. Our top speed, according to my watch, is 22.9.

But every downhill has uphill, and way too soon we’re furling the gennaker, lashing it to the trampoline, rounding an orange tetrahedron, and pointing three bows into steep, wind-whipped waves.

“More trim!” is all I hear for the next hour, or “More speed!”

Each time, I pull with everything I’ve got, the rope shredding the palms of my cheap gloves. With only the leeward bow in the water, Cry Baby kisses wavetops, making this upwind slugfest that much more enjoyable as we short-tack the island’s coastline. After one final tack to port at the top of the island, Altiere gives us the command we’ve been waiting for: “Go gennaker, now!”

The moment that sucker fills, the daggerboard is singing, water is exploding through holes in the trampoline mesh, and we’re cruising at 20 knots. Altiere carves up and down following seas and reels in the boat to leeward of us as if it’s dragging a drogue. The three of us are pinned to the aft beam, weight back as far as it can possibly go. There will be no pitchpoling today. Lush green island to starboard, sparkling blue sea all the way to the finish. It’s heart-racing tropical sailing the likes of which I’ve never experienced.

Later, as I shuffle to a hotel shower, I get a pop-up alert on my Garmin watch that I’ve never seen before: “Recovery Time Delayed. A high level of activity today slowed your recovery.”

As if I need reminding.

The New Yorkers had a heck of time getting around, unaware of water pouring into an unsealed cockpit hatch, enough to have their Torquedo floating inside the hull. “We were hanging with everyone until we got to the top of the island,” Ferraro says. “But once we got around the top of the island, everyone just peeled away from us. We had no idea why.”

Hundreds of pounds of water sloshing around the center hull will do that to you.

Regatta organizers serve up a feast for the next day, with a full menu that includes a 20-mile distance race to Marigot Bay on the French side of the island, a windward-leeward race in the bay, and a return distance race. Our new crew for the day is 13-year-old local Optimist champ Sarah Micheaux, tiny and timid, but seemingly game for her first Diam outing. She speaks only French, so Altiere explains the ropes.

Before we even strike the line on a high-speed gennaker reaching start, Micheaux is shivering, puking, and white-knuckling Altiere’s leg. While redlining at 20 knots, he pats her on the back like a tender father, assuring her that all is well.

We round the reach mark with Micheaux out of commission, so he hands the tiller to me so he can go forward and rotate the mast by hand. It’s my first go at driving, and my tendency is to drive it like a monohull—oversteering through waves and feathering through the big gusts. Altiere corrects me and keeps goading me: “More speed. Even more speed. Good.”

All I have to do is bear away a few degrees, get the center hull unstuck, and the boat levitates with only the leeward bow punching through the waves.

“See?” he says. “Speed. Always more speed.”

After the ensuing and harried one-lap windward-leeward race in the bay, we’re lining up for the 12-mile return sprint, which is another shot-out-of-a-cannon gennaker start. Thankfully, this race has zero upwind sailing. This one’s a reach-fest, and this is why we reach through life.

“The sail back from Marigot was just epic,” Holmes says. “Just screaming. Unbelievably fun. We were finally starting to get a handle on the boat.”

On the fourth and final day, we’re back to buoy racing, and while there’s more tears than cheers on Cry Baby , the sort-of New Yorkers are feeling their mojo.

“We were in the mix,” Holmes says. “We had good starts, and we were with the group upwind. There are some cool photos of us kind of like leading the bulk of the fleet around the course—at least that’s what it looks like.”

Ferraro agrees that they were sharp upwind, “but downwind, we just couldn’t find the low and fast mode. We couldn’t figure that out.”

That’ll be next year’s challenge.

 “I’m looking into buying one,” Holmes says, weeks later, back in the office and scheming with Young to go in on it with him. “It’s easy to get to St. Maarten, and from what I’ve seen, they have these cool regattas and beach parties, the sailing is amazing, and it all looks like so much fun. I think about that boat every day, so I definitely have to get back on it.”

Ferraro is hooked as well. “I can honestly say that after all the stuff that went on during the week, good and bad and stuff like that, even with all the chaos and stuff. That was still the most fun sailing I’ve had in a really long time.”

When, and if, they do get their hands on a Diam, there’s only one place they plan on putting it. “If you’re going to do it right, you gotta keep it in St. Maarten,” Young says.

And that’s how Altiere and his St. Maarten crew will get to 20 boats soon enough. If space on Kim Sha becomes an issue, no problem, he says. There are plenty of beaches on St. Maarten to spread the fun around.

“We’ll figure it out,” Altiere says. “I know we can make this work. The dream is real, and there is room for this kind of full-service experience. It’s a gateway to a sailing vacation.”

The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.

DaggerBoard

The Diam 24 is equipped with a daggerboard keel. A daggerboard is a lifting keel that can be lowered and raised, allowing the boat to enter shallow waters as well.

The boat can enter most marinas as the draft is just about 1.50 - 1.60 meter (4.92 - 5.22 ft) dependent on the load.

Her history

A one-design trimaran

Designed by the VPLP naval architectural firm, the Diam24 is a one-design trimaran measuring 7.25 metres in length launched in 2010 and selected to be the Tour de France à la Voile boat from 2015. That same year, Spindrift joined the circuit, participating in the season’s events. Dona Bertarelli and Yann Guichard’s team promptly began their quest for accolades, taking the win in the Spi Ouest-France and going on to secure victory in the Grand Prix de l’Atlantique a few weeks later. The 26 July 2015 marked the season’s high point for the team. Following a month-long competition, it was the city of Nice which saw the efforts of Spindrift team justly rewarded by victory in the Tour de France à la Voile.

Diam 24 is a 23 ′ 9 ″ / 7.2 m trimaran sailboat designed by Van Peteghem/Lauriot-Prevost starting in 2014.

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)

Sail area: Mainsail: 22m²/237 sq.ft. Solent 10m²/108 sq.ft. Gennaker: 32m²/344 sq.ft. Selected for “Tour de France à la Voile’ - 2015.

Crown the Champions! Merlin Tops Impressive Diam 24 Class, Nemo Wins CSA 1 in Fine Final Day of Racing in the Caribbean Multihull Challenge

On the fourth and final day, thankfully, the easterly breeze for which the islands are known at last made an appearance, and the racing classes in the Caribbean Multihull Challenge Race and Rally enjoyed a full slate of competition to wrap up the event’s excellent 6 th edition. Two champions were crowned: With three firsts and a third in the last four races, Alexis de Boucad’s Merlin captured the 10-boat Diam 24 division; and with a trio of bullets in as many starts, Todd Slyngstad’s HH66 was the undisputed winner of the 9-boat CSA 1 class. For both boats, their dominant performances on the final day left no doubt about the rightful victors.

The Diam 24 class, growing by leaps and bounds in St. Maarten and France, is an unquestioned success story in and of itself. Designed by the French naval architecture consortium VPLP, the 7.24-metre (23.8 feet) trimaran has a dedicated 5-race series in the islands called the Diam Tour Caribbean, which includes both the CMC and the renowned St. Maarten Heineken Regatta. St. Maarten sailor Pierre Altier, who campaigns his own Diam 24, Cry Baby , and offers several others to race through his local charter business, has been a driving force in promoting the fun, fast one-design tri. Cry Baby sailed a solid regatta, finishing fourth overall.

But de Boucaud’s Merlin was the cream of the crop, raced to near perfection with an all-star team that included well-known rock-star racing sailor Benoit Champanhac and Ivan Skobtsov in its three-man crew. Champanhac is on a serious roll, having won the Diam class in last year’s edition of the Heineken Regatta in undefeated style.

That said, coming into the final day of competition, Merlin held a tenuous three-point lead over another well-sailed St. Maarten entry, Erick Clement’s Karibuni , with another top team that includes local racer and Board Member of the SMYC Joris vanden Eynde and St. Maarten Yacht Club racing coach Sam Peeks, who holds an impressive sailboat-racing resume of his own. It’s been said you can’t win a race on the starting line but you can certainly lose one, and such was the case with Karibuni ’s first race of the day. Opting to attempt a risky port-tack start, Karibuni was forced to crash tack ahead of a starboard tacker and got hung up on the pin end of the starting line. Though Clement managed to extricate themselves and made a strong comeback to finish third in that contest, with Merlin ’s flawless performance on the day, Karibuni ’s fate was sealed. Still, their second-place overall result for the CMC regatta remained impressive.

Oddly enough, in the day’s first race in the CSA 1 class, an almost exact scenario unfolded. At the start of the day, Slyngstad’s Nemo was deadlocked with Riccardo Pavoncelli’s Gunboat 66, Mano , with identical scores of 6 points apiece. Mano also tried to port tack the fleet, but the aggressive tactic backfired when they were forced over the line early and had to restart while Nemo charged ahead unchallenged. In the grand scheme of things, Mana , which finished second in CSA 1,never fully recovered, as Nemo sailed faster and higher for the remainder of the day.

With easterly breeze that fluctuated between 5-10 knots for most of the day, principal race officer Chris Mansfield had a challenging task to get in several races, and handled it all with aplomb. After a light-air first race down the south coast of St. Maarten, he opted to set a shorter windward/leeward racecourse in Simpson Bay for the remainder of the day’s competition, and was able to conduct four races for the Diam 24’s and three for the CSA 1 sailors. It was a terrific way to finish the regatta.

But the unsung heroes of the day were Arthur Banting and his team aboard Tryst , the ancient Newick-designed trimaran originally launched in 1968. Not only did Tryst put together an excellent score for the day of a second, third and fourth on corrected time, the bright-red tri beat several larger yachts on a boat-for-boat basis, including Marc Guillemot’s 52-foot cat Dazeilad , the Kelsall 47 tri Triple Jack and the ORC 50 catamaran Calamity. Bravo Tryst !

Finally, the excellent all-around day of sailing was punctuated when, at the start of the third race, to the south the spinnakers of the Rally participants began to appear on the horizon on their return trip from their overnight visit to St. Barth’s. CMC founder Petro Jonker’s Seaduction , flying its multi-colored chute, was among the leading pack. It was a fine reminder that there’s more than one way to enjoy the Caribbean Multihull Challenge.
