2024 Boat of the Year Best Trimaran: Dragonfly 40 Ultimate

• By Dave Reed
• December 20, 2023

“Classy.” That was the first word that came to mind for Boat of the Year judge Mike Ingham when he stepped aboard the formidable 40-foot trimaran from Dragonfly, an unexpected and welcome late entry to the competition in Annapolis. “It almost feels as if the boat is intentionally understated but overdelivered because once you start looking closer at the details and craftsmanship, it just keeps getting more impressive.”

Builder and company owner Jens Quorning, whose family has been building trimarans in southern Denmark since 1967, says the Dragonfly 40 is the biggest boat they now build and a worthy holder of the flagship title. “Building a boat of this scale is complicated,” he says of the folding trimaran. “It takes three years to develop a new design, and this is for owners looking for a bigger boat, with better performance, capable of more long-distance sailing.”

The result is a powerful trimaran aimed at experienced owners who appreciate the sheer pleasure of racing and cruising on three hulls. This is not your average production multihull. It is a powerful and luxurious sailing machine capable of knocking off fast miles in comfort. Slip down below and you’re immediately immersed in a master class of woodwork and joinery. There are berths for four, including a giant master under the cockpit, plenty of standing headroom, and a comfortable salon and galley arrangement that’s monohull-cozy. “We do not offer a big house on the water,” Quorning tells the judges. “But if you really want a fine and elegant yacht with double-digit sailing, this is what we do.”

For our tests, Dragonfly presented its Ultimate edition, the midrange version. An upscaled Performance model is an all-carbon version with a taller mast. And in the lightest wind of the week, sub-10 knots, the trimaran teased the judges with its potential. Still, in the light stuff, the boat delivered a winning experience.

“It was a dream to sail upwind and downwind, almost effortlessly,” Ingham says. “With the gennaker up, at about 100 degrees true, we were going faster than the wind, and with winch pods on each side of the steering wheel, everything was as ergonomic as you could possibly imagine. The electric winches made it a cinch to furl and unfurl the headsails through the tacks and jibes, and the sails trimmed in perfectly every time.”

The feather-light feel of the helm, Ingham adds, was as smooth as a balanced dinghy. “With tiny movements on the wheel, the boat would immediately respond, but I could also walk away from the helm for a few minutes and the boat would stay right on track. Crazy—I think it steered itself better than I did.”

That’s the trait of a good trimaran, Greg Stewart says. The Dragonfly 40 has a lot of buoyancy in the bows, and while the center hull is substantial, the tall trussed rig and square top mainsail provide plenty of power. “The biggest thing that struck me is how easily accessible everything is,” Stewart says. “Clearly, every detail is painstakingly thought out, and I can’t believe how beautifully built the interior is. It’s top-notch, from the glasswork to the paintwork inside and out. Down below, we were all blown away by the finish.”

There’s no denying the boat is expensive at upward of $1 million, but the test boat had quality race sails, a full electric-winch package, and a long list of high-spec extras. At nearly 15,000 pounds light, it’s a substantial boat—not trailerable, but foldable with Dragonfly’s trademark technique that Corning describes as mimicking parallel rules. The floats are 2 feet longer than the center hull, with buoyancy pushed well forward into the reversed bows, and the center hull is narrow at the waterline before sweeping upward to a high and hard chine. This pronounced hull shape allows for the generous amount of headroom, and high bench seats that flank a long centerline table, which can, of course, drop down to create a double-size berth.

Allen noted that the center hull’s wide side decks provide a secure pathway to the bow, rather than across the trampolines. He was also impressed with the ease of sailing the boat and the comfort belowdecks. “When we were doing 9 knots, I went below and there was silence. It’s comfortable and beautiful. It would be a blast to do some long point-to-point racing on it, doublehanded or with like a crew of four, max.”

Stewart agreed, adding that beyond its noteworthy gunkholing attributes, the engine is well aft on the center hull, allowing it to be motored safely into shallow anchorages. The daggerboard is mechanically raised into the trunk, and the rudder kicks up. “I also think it would be great for a distance race or rally type of event,” Stewart says. “Its performance and versatility are what appeal to me, but the build quality is what really sets it apart.”

Dragonfly 40 : Fast now even faster

Hauke Schmidt

The competition of the Dragonfly 40

More space than expected below deck, the measured values for testing the dragonfly 40, the dragonfly 40 in detail, equipment and prices, yacht review of the dragonfly 40.

An update on the Dragonfly 40 : 25 boats had been sold by spring 2024, a considerable number considering the size and cost. But that's not all: together with Marström Composites in Sweden, Quorning Boats has developed an even more technically complex variant. Around half of the boat is manufactured using carbon prepregs in an autoclave under pressure and heat - the top shelf in modern boat building. In this way, both floats, all four beams, the two main load-bearing bulkheads in the centre hull, the centreboard box and the rudder are produced. These measures reduce the weight of the boat by around 1000 kilograms to just 4.8 tonnes. The centre hull is too complex for this construction method and the autoclave is too small, according to company boss Jens Quorning. He had expected to be able to sell only three to four units of the new hybrid carbon version, but has already been able to win over six customers. And this despite extremely increased costs. This is not only due to the higher carbon fibre part, but also to the new moulds required, which had to be made from solid carbon laminate for use in autoclaves and can withstand 120 degrees Celsius as well as the high pressure. The Dragonfly 40CPerformance costs from 1,095,000 euros including VAT.

Below is the test of the normal version Silver grey metallic, or in the language of automotive colour theory: lazurite blue. The Dragonfly's paintwork is very unique. What's more, it's a colour that's mainly used for large SUVs. The contrast could hardly be greater, because at 5.8 tonnes, the new twelve-metre-long Dragonfly really isn't a heavy SUV. Admittedly, the vehicle doesn't look very elegant when folded down to four metres. The floats press against the main hull and give the Tri a rather motorboat-like silhouette, especially as there is only a protruding bow and stern pulpit instead of a railing.

The casting off manoeuvre is also similar to that of a motorboat, as the stern of construction number 1 has a whopping 90 horsepower instead of the usual 40 hp. The lavish motorisation weighs only 40 kilograms more and is intended to enable fast cruising, but more on that later. For now, the power makes for a foaming wake. The extendable bow thruster is a welcome help when turning against the strong crosswind, as the Tri hardly dips and therefore has little lateral surface area, but is over 14 metres long when folded. Once under way, the centreboard and rudder work very well and the Dragonfly is very easy to manoeuvre.

Things get exciting again outside the harbour. The vessel has to be unfolded for sailing. In fact, the manoeuvre is limited to opening two halyard stoppers on each side and briefly using the standard E-winches. To increase the stability of the Tris, the floats are pushed deeper into the water when folded; their buoyancy therefore helps when unfolding. Only the last few metres of the endlessly sheared operating line have to be pulled through using the electric winch. The whole process takes less than a minute. Finally, the backstays are pushed through and the rig is tensioned with them.

• Test Neel 43: Lively Tri with sober functionality

As soon as the mainsail is set on the 2:1 halyard, the fun begins. The test boat is the Ultimate version with a higher rig, better equipment and an overlapping headsail. The squarehead main alone brings 75 square metres to the wind. The genoa provides a further 38, and the Code Zero has an area of 80 square metres. In the tamer touring version, the main and self-tacking jib together measure 90 square metres.

With no braking ballast and the enormous stability of the 8.40 metre beam, the wind energy is instantly converted into speed - sometimes an unusually dynamic undertaking in 14 to 22 knots of wind. You've just enjoyed the almost double-digit speed when a push catapults the Tri forwards and the logs rush upwards. Apart from the pure acceleration, little of this is noticeable; unlike a monohull, the heeling practically does not increase.

20 knots are easily reached

Only the rudder pressure seems disproportionately high for the first few miles. Designer and shipyard boss Jens Quorning quickly found the solution: The retractable rudder is not in the lowest position. Shortly before the test, the system was checked and the downhaul was probably not fully pushed through; small cause, big effect. With the correct blade position, the Tri hangs on the handlebars like a go-kart. The direct response to steering commands is also necessary, at least if you want to utilise the Dragonfly's full potential in gusty weather.

The rapid changes in speed require equally rapid and courageous course corrections in order to follow the apparent wind. This becomes particularly clear under Code Zero. The Tri carries the additional 80 square metres of cloth without any problems. As long as the wind doesn't drop too much, the log almost always shows 17 knots or more. As soon as the water surface upwind turns a telltale dark colour and announces a gust, it's time to drop off. 18, 19, 20 knots, the picturesque landscape of the Little Belt flies by and requires frequent gybing.

The lack of a traveller is noticeable here. So that the almost rectangular mainsail can also be trimmed to leeward without a carriage, an auxiliary tackle is rigged on the lee beam in addition to the sheet. Although the twist of the sail can be easily adjusted with the two tacking buoys, the auxiliary tacking buoy has to be taken off before every manoeuvre and attached again on the new bow - a bit tedious in narrow waters, so you will probably have to do without the perfect sail trim in touring mode.

The Dragonfly 40 accelerates enormously - but sails in a decidedly unagitated manner

It's also annoying that we have to return to our home harbour, because that means cruising. Not that the Dragonfly doesn't go upwind, quite the opposite. Thanks to the low water resistance and the very small sheeting angles, turning angles like a monohull are possible, and still at significantly higher speeds. The boat usually logs between 8 and 9 knots.

However, the helmsman must steer very carefully. The neutral but direct layout requires full concentration, as it offers little feedback, and the sails, which are cut flat for high speeds, are hardly forgiving of wrong currents. In other words: the Tri sails well, but if the helmsman is not fully focussed, it is easy to miss a knot or the boat sails 10 degrees too low.

There is little to worry about when tacking. As the floats hardly dip into the water without sail pressure, the Dragonfly turns very well through the wind. "If there's a lot of wind and waves, we recommend feathering the mainsheet slightly before tacking so that the sail doesn't exert so much pressure and the boat picks up speed more quickly on the new bow," says tri pro Quorning.

Light & safe

The floats offer a great deal of buoyancy and therefore large safety reserves, whether at the cross or during a space sheet ride. Even in heavy pushes, the boat builds up speed instead of diving away. This should not change even with a full holiday load. According to the shipyard, 1.8 tonnes can be loaded. This means that even a fully equipped Dragonfly weighs around 500 kilograms less than an empty monohull of comparable length, such as an X 4.0.

And this despite the fact that the shipyard only uses carbon fibre for the mast profile. The hulls are laminated by hand. Wherever possible, Divinycell sandwich is used, and the required laminate thicknesses are precisely calculated. As no keel forces have to be introduced, the structure looks completely different to that of a monohull. Enormous loads occur in the area of the forward beams in particular. For this reason, there is no square door in the passageway to the forecastle, only an oval opening. "The bulkhead has to withstand up to 25 tonnes of pressure," says Quorning. "We can't make a larger hole." The beams are also subjected to extreme loads; they are laminated in an infusion process under vacuum and then annealed.

Plastic parts and rig manufactured in our own workshop

To ensure the desired lightweight construction and quality, the shipyard manufactures the plastic parts itself. Quorning Boats has a total of five sites in and around Skærbæk. Dismantling and final assembly also take place there, at the shipyard's headquarters. To prevent deformation, the hulls are stored in precisely fitting negative moulds.

Even the rigs are produced in the company's own workshop; only the bare carbon fibre tube is manufactured by a supplier. Standard masts with a teardrop-shaped profile are out of the question for Quorning. "Our round masts have less wind contact surface, which is important in extreme crosswinds and with folded floats," explains the shipyard boss.

On the last few miles to the harbour, the engine has to be tested. Theoretically, the powerful engine should be sufficient for comfortable cruising beyond 11 knots. The shipyard had already trialled this concept on the predecessor model, the Dragonfly 1200. However, the set-up on the 40 is not yet perfect. When accelerating, the powerful diesel engine pushes very hard, but the cruising speed of around 8 knots is hardly any higher than would be expected with the standard engine, which is half as powerful, and this results in strong vibrations.

Quorning is also not satisfied with this result. His assumption: the engine power requires a very large propeller, the distance between it and the fuselage is too small. This causes turbulence and eats up power. A longer saildrive should solve the problem. Falling dry should also not be a problem with the drive projecting further downwards.

The shipyard boss is proud of the 40's space utilisation. The living space below deck on trimarans is usually tight, as only the slim centre hull is inhabited. The Dragonfly is no exception to this rule, but the bulkhead shape of the main hull significantly increases the usable volume. While the underwater hull is slim and sharply cut as before, the width above the waterline increases abruptly, creating more space. A positive side effect: the step in the side wall acts as a water deflector, so the Dragonfly sails dry even at high speeds.

The layout corresponds to the classic monohull standard with an aft cabin. This was not previously the case with Dragonfly: either the aft berth was open to the saloon as on the 35, or it was completely separate and only accessible from the cockpit. Surprisingly, although the cabin is under the cockpit, it offers a pleasant amount of headroom. The obligatory escape hatch provides a view of the sea, and a deck hatch lets additional light into the cabin. The corner-opening wardrobe with compartments integrated into the door is a clever solution.

The rest of the ship is also bright. In the saloon, the wide window strip and three large deck hatches provide daylight. The hull windows installed in the test boat are also available on request. The side windows in the foredeck are standard.

Classic room layout with excellent workmanship

The integration of the centreboard box is a good solution; it replaces the table base and extends under the pantry block, so the massive component hardly interferes. The high seating position, on the other hand, is unconventional. In order to utilise the additional width of the hull, the saloon bays are unusually high. This means that the feet on the starboard side have no contact with the floor. A footrest can therefore be folded out for comfortable seating.

Overall, the interior fittings leave a very good impression. The woodwork, with its many moulded coamings and edgings, is just as flawless as the silk-matt paintwork. The gaps are perfect and the grain of the unusual elm veneer is beautifully harmonised. Quorning thus presents a level of maturity that is rarely found in prototypes.

However, the price is also in a class of its own. Even the 785,800 Euro for the basic boat are not favourable. If you look at the price per knot, the calculation looks better, because even a Shogun 50, which is twice as expensive, does not sail nearly as fast with a small crew, not to mention the maintenance costs of the 50-footer.

Dragonfly boss and designer Jens Quorning shows Toby over his new flagship, the Dragonfly 40

The Dragonfly 40 is bristling with neat touches and feels much larger than a 40ft trimaran might, both on deck and below.

The latter is the result of a combination of clever design features that encourage the brain to assume there’s more volume, combined with attention to detail and taking the trouble to build in accessible stowage wherever feasible.

I was initially sceptical about the Dragonfly 40’s twin wheels, as my preference is for tillers whenever possible, which shouldn’t be an issue on a multihull of this size.

However, the execution is extremely good – there’s enough cockpit width to have good separation between the pedestals, while there’s easy access to the electric winches and to the low-profile built-in pods for MFDs and instrument displays on each side of the boat.

Another nice touch is transom hatches for the floats that enable an inflated kayak to be easily stowed inside each one. Below decks there’s a two double cabin layout, with the aft one being the more spacious, with neat solutions to make use of corners that would otherwise be inaccessible.

While the Dragonfly 40 is far from the lightest trimaran of this size, it’s impressively civilised, with an air of quality throughout, and offers the very enticing prospect of passage making at speeds of 24 knots.
