Ocean Bird
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. Overview Owen provided an overview in a 1970 review of the sailing craft. He noted the following: * Multihulls owe their stability to their wide stance, which provides less yielding of the rig to heeling and thereby requires stronger support of the mast and rigging, but allows a much shallower draft than for a monohull. The vessel has a centreboard, instead of a fixed keel to minimize leeway. * Ocean Bird trimarans are configured as "a monohull with two smaller, sleeker wing hulls mounted as outriggers". The outriggers fold in toward the main hull, when needed to save space when in harbour—a configuration that allows for motoring, but not sailing. * The vessel has two berths forward, a marine ...

Trimaran
A trimaran (or double-outrigger) is a multihull boat that comprises a main hull and two smaller outrigger hulls (or "floats") 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. Terminology The word "trimaran" is a portmanteau of "tri" and "(cata)maran", a term that is thought to have been coined by Victor Tchetchet, a pioneering, Ukrainian-born modern multihull designer. Trimarans consist of a main hull connected to outrigger floats on either side by a crossbeam, wing, or other form of superstructure—the traditional Polynesian terms f ...
