A trimaran is not a catamaran with an extra hull. The architecture is fundamentally different: one main hull carries the crew, accommodations, and ballast (such as it is), flanked by two smaller outriggers called amas that provide righting moment and prevent capsize. The amas touch the water only when the boat heels — in a dead calm they may be airborne. This arrangement produces a boat that is lighter, faster, and more extreme than a comparable catamaran, with trade-offs that explain why you see far fewer tris in cruising anchorages.
How a Tri Differs from a Cat
The catamaran's two hulls are approximately equal in size and both carry crew and gear. Accommodation is spread between the two hulls and the bridgedeck saloon. The boat is wide and stable by design, and even in severe conditions, a capsized catamaran floats hull-up, providing a platform for rescue.
The trimaran's main hull carries everything significant — crew, fuel, water, stores — while the outrigger amas are there purely to keep the boat upright. This concentration of weight in the center hull, combined with the amas' buoyancy at the extremes, creates a more powerful righting moment per unit of beam than a catamaran of the same width. The result is a boat that can carry more sail, generate more speed, and sail closer to its theoretical maximum more of the time.
The accommodation difference is stark. A 40-foot trimaran lives like a 35-foot monohull: one main cabin, one head, and minimal space for anything that doesn't have a dedicated place. This is fine for racing and daysailing, workable for passage-making with a small crew, and cramped for extended liveaboard cruising. Cats win on interior volume without contest.
Racing Tris: ORMA 60, Ultim Class, and the Jules Verne Record
The offshore racing record books belong to trimarans. The ORMA 60 class — open 60-foot racing tris — dominated transatlantic and round-the-world records through the late 1990s and 2000s. These boats, sailed by a small professional crew, were capable of 30-knot average speeds on downwind passages and regularly logged 600+ mile days.
The Ultim class, which replaced ORMA 60 as the premier offshore racing multihull class, is a different species entirely. Ultim tris are 100-foot foiling platforms capable of 50+ knots in optimal conditions. They fly on hydrofoils — the hulls leave the water entirely — sustained by computerized foil control systems that adjust automatically to sea state and wind. These are the boats contesting the Jules Verne Trophy for the fastest circumnavigation.
The Jules Verne Trophy — awarded for the fastest non-stop circumnavigation of the globe with no outside assistance — has been held by trimarans since Francis Joyon's 2004 record on IDEC. The current record stands around 40 days, set by Spindrift 2, a massive foiling trimaran. To put that in perspective: Magellan's crew took three years on the first circumnavigation. A well-found cruising monohull doing the circumnavigation in a year is considered impressive. Forty days by sail, with no stopping, is a different kind of sailing.
Cruising Tris: Corsair and Dragonfly — The Folding Solution
The obvious problem with trimarans for cruising is beam. A tri wide enough to be stable and fast at sea is too wide for a standard marina berth. Ian Farrier's solution — developed across decades of design work and commercialized through the Corsair brand — is the folding trimaran: amas that swing inward on a hinge system, reducing the boat to monohull beam for marina berthing and trailering, then deploying quickly once offshore.
Corsair tris from 24 to 37 feet have been built in large numbers since the 1980s. They are the most common cruising trimaran in the world, found in significant numbers in the Pacific, Australia, New Zealand, and along both US coasts. The Corsair 37 Sprint — a performance-oriented trailer sailor — will see 20+ knots in 15 knots of breeze and can be launched and retrieved with a standard boat trailer, making it genuinely trailable for sailors who want to explore different cruising grounds rather than keeping a boat in one place.
Dragonfly, a Danish builder, produces a similar range of folding performance cruising tris from 25 to 40 feet. The Dragonfly 32 and 40 are regarded as somewhat higher-quality builds than the Corsair equivalents, with more refined interiors and better hardware. Both brands attract a dedicated following of sailors who want genuine speed without the marina beam problem.
Offshore Tris: Neel and the Farrier Bluewater Designs
For cruising that goes beyond coastal day-sailing, the Neel line from France represents the most serious attempt at a production offshore cruising trimaran. Neel tris — the 45, 47, 51, and larger models — are designed around the concept that a trimaran can provide genuine bluewater capability with substantially more accommodation than earlier cruising tri designs allowed.
The Neel 45 in particular has earned a following among experienced bluewater sailors who find production catamarans too slow and too bulky. The boat is not fast by racing tri standards, but it is meaningfully faster than a comparable cat — 15 to 20 percent better VMG in most conditions — while providing accommodation that is genuinely comfortable for two people and workable for four. The folding system handles marina berthing. The construction is French premium quality.
Ian Farrier designed a range of larger non-folding tris for bluewater use before his death in 2019. The F-82R and similar designs represented his view of what a properly built offshore trimaran should look like: structurally conservative, with adequate tankage and systems, capable of being handled by a couple for extended passages. A number of Farrier designs have completed circumnavigations. The designs continue to be built by licensed builders.
The Performance Envelope: What 30 Knots Actually Feels Like
A performance cruising trimaran — a Corsair 37, a Dragonfly 40, or a Neel 45 in good conditions — can reach 25 to 30 knots in a fresh breeze. At these speeds, sailing is a physical and cognitive experience quite different from anything a monohull or production catamaran provides. The boat feels alive in a way that can be either exhilarating or terrifying depending on the sailor's experience level.
At 25 knots, small waves become significant. Wind noise is substantial. A broach or Chinese gybe at these speeds is a serious event. Offshore performance tris are not forgiving of sail handling errors in the way that a heavy production cat is forgiving. They reward experience and punish inattention.
For experienced offshore sailors who have developed solid multihull skills, this performance envelope is genuinely compelling. The ability to make passages at twice the speed of a monohull — consistently, not just in favorable conditions — changes the practical calculus of long-distance cruising. The same passage takes half the time, meaning fewer days at sea and proportionally less exposure to weather windows closing around you.
The Capsize Question
Trimarans capsize more readily than catamarans in extreme conditions. This is a consequence of their architecture: the amas are smaller than catamaran hulls, and under enough wind pressure, particularly in a broach with the main fully up, the windward ama can lift and the boat can go over. Once inverted, a trimaran is extremely difficult to right without outside assistance. The hulls are not designed to be lived on upside down the way a catamaran can be.
The "unsinkable" argument that some tri sailors make is technically correct — well-built glass tris float, and the inverted boat provides a platform — but it glosses over the practical reality that a capsized trimaran in the open ocean is a rescue situation. Racing programs accept this risk as part of competition. Cruising sailors should assess it honestly.
The risk is manageable with conservative sail handling, good sea sense, and avoiding the conditions that create capsize scenarios. Many sailors cruise tris for decades without incident. The risk is real but not inevitable.
Why Tris Are Rare in Charter Fleets
Charter operators avoid trimarans for three practical reasons: beam, liability, and righting difficulty. A tri that folds to monohull beam requires the operator to trust charterers to deploy and stow the amas correctly — a mechanical process that introduces failure modes charter companies prefer to eliminate. An unfolded tri needs specialized berths that most marinas do not provide.
The liability dimension of the capsize risk is significant in charter operations. Even if the statistical risk is low, the consequences of an inverted trimaran with inexperienced charterers aboard are severe enough that no major charter company has found a way to offer tris to the general market. You will not find a Dragonfly 40 in a Sunsail fleet. That market belongs entirely to catamarans.
For sailors who own their boats and have the experience to handle them, trimarans represent a legitimate and compelling alternative. For everyone else, the catamaran remains the practical multihull choice — which is why the world's charter anchorages look the way they do.
Frequently Asked Questions
How does a trimaran's architecture fundamentally differ from a catamaran? A trimaran has one main hull carrying crew, accommodations, and whatever ballast exists, flanked by two smaller outrigger amas that touch the water only when the boat heels — in a dead calm they may be airborne. A catamaran's two hulls are approximately equal in size, both carrying crew and gear, with accommodation spread between the two hulls and a bridgedeck saloon. The trimaran's concentration of weight in the center hull combined with the amas' buoyancy at the extremes creates a more powerful righting moment per unit of beam, producing a boat that can carry more sail and generate more speed.
What speeds are achievable on a performance cruising trimaran? A performance cruising trimaran — a Corsair 37, Dragonfly 40, or Neel 45 in good conditions — can reach 25–30 knots in a fresh breeze; the Ultim-class racing tris are capable of 50+ knots on hydrofoils in optimal conditions. The Neel 45 is described as 15–20% better VMG than a comparable catamaran in most conditions. At 25 knots, small waves become significant, wind noise is substantial, and a broach or Chinese gybe is a serious event — performance tris reward experience and punish inattention, unlike heavier production cats.
What is the folding trimaran solution and which builders offer it? Ian Farrier's folding trimaran design allows the amas to swing inward on a hinge system, reducing the boat to monohull beam for marina berthing and trailering, then deploying quickly once offshore. Corsair tris from 24 to 37 feet have been built in large numbers since the 1980s and are the most common cruising trimaran in the world; the Corsair 37 Sprint will see 20+ knots in 15 knots of breeze and can be launched and retrieved with a standard boat trailer. Dragonfly, a Danish builder, produces a similar range of folding performance cruising tris from 25 to 40 feet with generally more refined interiors.
How does the capsize risk on a trimaran compare to a catamaran and what are the practical implications? Trimarans capsize more readily than catamarans in extreme conditions because the amas are smaller than catamaran hulls — under enough wind pressure, particularly in a broach with the main fully up, the windward ama can lift and the boat can invert. Once inverted, a trimaran is extremely difficult to right without outside assistance; the hulls are not designed to be lived on upside down the way a capsized catamaran can be. The risk is manageable with conservative sail handling and good sea sense — many sailors cruise tris for decades without incident — but it is real and should be assessed honestly rather than dismissed.
Why do charter fleets avoid trimarans despite their speed advantages? Charter operators avoid tris for three practical reasons: beam, liability, and righting difficulty. A folding tri requires charterers to deploy and stow the amas correctly — a mechanical process that introduces failure modes charter companies prefer to eliminate. An unfolded tri needs specialized berths most marinas cannot provide. The liability dimension of capsize risk is significant: even if statistical risk is low, the consequences of an inverted trimaran with inexperienced charterers are severe enough that no major charter company has found a way to offer tris to the general market. The catamaran holds the charter market entirely for these reasons.
What trimaran holds the Jules Verne Trophy and what does the record represent? Spindrift 2, a massive foiling trimaran, holds the current Jules Verne Trophy record at approximately 40.5 days for a non-stop circumnavigation with no outside assistance. To put that in perspective: Magellan's crew took three years on the first circumnavigation; a well-found cruising monohull doing the circumnavigation in a year is considered impressive. The Jules Verne Trophy has been held by trimarans since Francis Joyon's 2004 record on IDEC, reflecting the dominant offshore racing capability of the trimaran architecture.
