A multihull is a ship or boat with more than one hull, whereas a vessel with a single hull is a monohull.
A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture.
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."
Dragonfly Trimarans is a line of trimaran sailboats built by the Quorning Boats shipyard in Skærbæk, near Fredericia, Denmark.55°31′11.97″N9°38′8.08″E
Randolph L. Smyth is an American competitive sailor and two-time Olympic silver medalist. He is a multihull specialist, who won two Olympic silver medals racing catamarans, and has won innumerable national and world titles skippering multihulls. In a 2003 profile on him in Sailing World magazine he was described as America's greatest multihull sailor. He was born in Pasadena, California.

Ed Horstman is an American naval architect and multihull sailboat designer. He was born in Kalispell, Montana. He made his way from Montana to California via the U.S. Air Force where was trained as a helicopter mechanic before serving 4 years in Korea. After the war on the GI Bill Ed attended the Northrop Institute of Technology where, he earned a bachelor of science degree in Aeronautical Engineering. He then worked for aviation giants like Boeing, Douglas Aircraft, and North American Aircraft where he did wind tunnel tests for the XB-70 supersonic bomber. Horstman designed his first trimaran after seeing an ad clipping for Piver trimarans. Ed wrote to Piver requesting information on his 35' trimaran, but never received an answer, so a friend, said, "You're an engineer, why don't you design one." Before starting, Ed took two courses on hydrodynamics from the University of Southern California before building a scale model out of foam with removable amas to determine the maximum beam and buoyancy. The model did not have a movable rudder, and when a gust of wind hit the model hard and it turned into the wind, he knew he got the design right. When he could not find a mathematical model to predict the stress on the beams, he again built models of the beams and put them through a battery of stress tests until he was satisfied that his scantlings were strong enough. Ed started the construction of his first trimaran, a 40 footer with $600 that he borrowed from his grandmother in 1961.
Other West Coast designers were strongly influenced by Piver, yet went divergent ways. Ed Horstman employed Boeing technology to create immense flush-deckers with accommodation in all three hulls—the dreadnaught class of trimarans.
Jay Kantola was an American naval architect who is most known for his work designing multihull sailboats. He began designing multihulls in the 1960's. Kantola was an early proponent of a vessel construction technique called cold molding and cored construction. Cold molding involves bending strips of wood at room temperature to form a desired shape. The shape is then retained by gluing the wood together using epoxy. When the shaped construction is coated with layers of fiberglass saturated with epoxy, the final construct is termed a cored or composite construction. Kantola was one of several designers that worked closely with Meade Gougeon, Joel Gougeon, and Jan Gougeon. These brothers are collectively known as the Gougeon brothers. They also designed vessels and founded a line of epoxy products called West System.
The Searunner 31 is a trimaran sailboat designed by Jim Brown in the 1960s. It is the most popular boat in the Searunner series, which includes models from 25 ft (7.6 m)—40 ft (12 m).
The Searunner 25 is a trimaran sailboat from the 1960s designed by Jim Brown. It is the smallest boat in the Searunner series.
The Searunner 40 is a trimaran sailboat from the 1960s designed by Jim Brown and John Marples. It is the largest boat in the Searunner series.
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.
Constant Camber 3M is a 10 ft (3.0 m) cat-rigged solo harbor racer/trainer trimaran sailboat designed in the 1980s by John Marples.
The F-31 Sport Cruiser is a family of American trailerable trimaran sailboats that was designed by New Zealander Ian Farrier and first built in 1991.
