A multihull is a ship or boat with more than one hull, whereas a vessel with a single hull is a monohull.
A trimaran is a multihull boat that comprises a main hull and two smaller outrigger hulls which are attached to the main hull with lateral beams. Most modern trimarans are sailing yachts designed for recreation or racing; others are ferries or warships. They originated from the traditional double-outrigger hulls of the Austronesian cultures of Maritime Southeast Asia; particularly in the Philippines and Eastern Indonesia, where it remains the dominant hull design of traditional fishing boats. Double-outriggers are derived from the older catamaran and single-outrigger boat designs.
Arthur Piver was a World War II pilot, an amateur sailor, author, printshop owner and legendary boatbuilder who lived in Mill Valley on San Francisco Bay and became "the father of the modern multihull."

The Ocean Bird is a class of trimaran sailboat designed by John Westell and produced by Honnor Marine Ltd. at Totnes, Teignmouth in the 1970s, featuring fold-in lateral floats on a webless steel-beam frame chosen to provide stability against heeling, yet allow a compact footprint in harbour.
Constant Camber 26 is a 26 ft (7.9 m) cruising sloop trimaran sailboat designed in the 1970s by John Marples featuring berths for two adults and two children. The constant camber hull is constructed using a single master template to produce each panel, resulting in a design with unchanging curvature, imparting extraordinary strength similar to an eggshell. The panels are laminated using a vacuum bagging technique, as described in Marples' article, "Backyard Vacuum Bagging," written for WoodenBoat Magazine. A unique and appealing feature, aside from its modular construction, is that her cross arms fold up and in, reducing her beam to just under 8 ft (2.4 m), making this trimaran fully trailerable.
