Hull form

Sailing Catamarans

Sailing Catamarans: YachtCodex lists 111 models, 9.3–35.5 m long. The builders with the most are Lagoon (10), Bali (9), and Fountaine Pajot (9). The largest in production is the Fountaine Pajot FPY 120S (35.5 m); the shallowest draft is the Seawind 1600's (0.60 m).

Two hulls set apart, which buys stability from geometry rather than from lead. A cruising catamaran sails level, draws little, and gives a family more room on a given length than a monohull can; the trade is that it does not right itself if it ever goes over, so its margins are designed rather than recovered. It is the form that has grown fastest in cruising over the last two decades.
