A trimaran is a three-hulled sailboat, featuring a slender main central hull for accommodation and two smaller outer hulls (outriggers or floats) for exceptional stability, speed, and safety. They are renowned for high-performance sailing—often exceeding wind speed—and are less prone to capsizing than monohulls, providing a flat, comfortable ride.

Key Characteristics:
Design & Structure: Comprised of a main hull for living space and two amas (floats) connected by beams, often with trampolines between them for lounging.

Stability & Safety: The three-hull design reduces the risk of capsizing and offers superior stability over monohulls and catamarans.

Performance & Speed: Trimarans are generally faster and more agile, often capable of flying one hull (lifting it out of the water) to reduce drag.

Interior Space: While the central hull is often narrow, modern cruising trimarans (e.g., Dragonfly, NEEL) offer comfortable accommodation, though generally less volume than a similarly sized catamaran.

Handling: They are known for efficient, quick tacking due to a central keel/daggerboard.

Versatility: Many modern trimarans (such as Corsair Marine models) feature folding beams, allowing them to fit into standard marina slips or be trailered.
