Since its introduction in 2017, 500 boats have been delivered, making the UFO the most widespread foiling dinghy of its kind.
Design and Construction
The UFO is a solid-decked catamaran measuring under twelve feet long and five feet seven inches abeam, with a light-ship weight of 110 pounds. The hull itself weighs 70 pounds, which makes it easy to manhandle.
Its hull is a vinylester-infused laminate, with a Soric foam core skinned in E-glass and minimal, strategically placed unidirectional carbon. The boat is assembled from two parts bonded along a single half-inch flange around the perimeter, forming simple two-piece, carbon-reinforced hulls and deck.
SAIL described the hulls and deck as built to be pretty much indestructible, with beach launching and hard dockings specifically in mind. The solid, nearly dent-proof shell and flat hull bottoms also allow the boat to be strapped securely to a car roof. Fulcrum’s literature emphasizes high-volume domestic production and tight quality control, intended to preserve one-design parity across the fleet.
Rig and Foiling System
The UFO uses a Moth-type foil package: a daggerboard mainfoil and a rudder fitted with horizontal lifting wings. A surface-sensing wand at the bow controls a flap on the mainfoil’s trailing edge through a linkage to the T-foil daggerboard.
The rig also shares some of its design with a windsurfing rig. A flexible sailboard spar bends into a provisionally patented “jumper strut” wishbone-boom arrangement. The deck is deliberately sparse, with only a Cunningham, mainsheet, and tiller.
Because the foil trunk sits just forward of the mast, the foil can be withdrawn between the hulls without fouling the rig during launching. Sailors can tune the wand for a high, aggressive flight, a low and slow ride, or even a no-fly mode. That range allows smaller sailors to dial the boat down.
Handling and Performance
The UFO takes off reliably in around eight knots of breeze, although ultra-light sailors have been filmed foiling in five knots. A 225-pound helm needs ten knots to lift off, while a 270-pound payload becomes airborne in twelve.
Below its takeoff threshold, the UFO sails as a pleasant displacement catamaran—tactical rather than frantic, though slow. Once airborne, it foils on every point of sail: upwind, reaching, and downwind.
The twin hulls provide stability that a Moth lacks. The boat is also easy to right after a capsize or even a full turtle. Over six years, it has demonstrated a particular aptitude for safe, consistent flight in strong wind. Where other foilers head ashore above 22 knots, the UFO keeps sailing. Documented outings in 36 knots show that its upper range demands skill, but doesn’t require sailors to retire from the action.
Purpose and Comfort
There are no accommodations in the conventional sense. The UFO is a single-person foiling platform with a sparse deck, tiny hulls, no enclosed volume, and no room for comfort or storage. Its design brief prioritizes efficient production, durability, shallow-water maneuvering, and forgiveness for amateurs rather than creature comforts.
Ownership and Transport
The UFO weighs under 50 kilograms, and its components collapse to fit inside a standard hatchback. It can be carried on a car roof and launched from a beach.
The foils retract above the waterline, allowing the hull to slide onto a dock float or boat deck without risk of foil damage. The current record for going from cartop to launched is close to fifteen minutes.
Its one-design discipline means a used boat can race on even terms with a new one. Fulcrum’s volume production keeps the class coherent.
The Verdict
The Foiling UFO is a rare boat: a genuine flying machine that ordinary sailors can own, carry on a car, and race head-to-head without an expert’s touch. It trades exotic materials and a brutal learning curve for smart, durable simplicity. Just as importantly, it makes foiling possible across an unusually broad range of wind speeds and crew weights.
Pros
- Fully retractable foils permit beaching, cartopping, and docking without foil damage
- Flies reliably from eight knots and, with a skilled sailor, can handle up to 36 knots
- Stable twin-hull platform is easier to right than a Moth
- One-design construction keeps racing fair and ownership simple
Cons
- Below eight knots, it’s merely a slow displacement catamaran
- Sparse deck and tiny hulls leave no room for comfort or storage
- Foiling in strong wind still demands focus and experience
