Sport catamarans are high-performance twin-hulled sailing boats, typically 14–20 feet, designed for racing and performance sailing rather than cruising or accommodation. They are sailed by one or two crew and are defined by light construction, powerful sail plans relative to displacement, and — on foiling variants — hydrofoil systems that lift the hulls clear of the water at speed.
The category spans a wide performance range. Entry-level classes such as the Hobie 16 are accessible to capable recreational sailors; top-end designs including the A-Class and Olympic Nacra 17 demand advanced technique and physical fitness, and are not appropriate for beginners. Crew typically work on trapezes to manage righting moment. Foiling variants in classes like the Nacra 17 and A-Class add a further technical layer: foil management at speed requires trained reflexes and significantly increases the consequences of errors. Capsize recovery is manageable but requires practised crew coordination.
Hulls are GRP or carbon composite sandwich, with carbon used on performance and racing-class designs where weight reduction directly affects speed. Masts are carbon on all competitive designs. There is no auxiliary engine. Most sport catamaran classes are governed by World Sailing-recognised class rules with active international racing programmes; the Nacra 17 is the current Olympic mixed-crew multihull class. Boats are trailerable and launched from beaches or ramps without marina infrastructure.
