A multihull is a ship or boat with more than one hull, whereas a vessel with a single hull is a monohull.
A yacht is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a yacht, as opposed to a boat, such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities.
A catamaran is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes.
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.
The Transpacific Yacht Race (Transpac) is a biennial offshore yacht race held in odd-numbered years starting off the Pt. Fermin buoy in San Pedro, California and ending off Diamond Head in Hawaii, a distance of around 2,225 nautical miles. In even-numbered years the Pacific Cup race starts out of San Francisco and is run by the Pacific Cup Yacht Club. Started in 1906 by Clarence W. Macfarlane and hosted by Los Angeles Yacht Club, it is one of yachting's premier offshore races and attracts entrants from all over the world. The race is organized by the Transpacific Yacht Club.
Hobie Cat is a company that manufactures sailing catamarans, surfboards, sailboats, kayaks, stand-up paddle boards, and pedalboards as the Hobie Cat Company. It was founded in 1961 by Hobart Alter, who originally manufactured surfboards. Its line of products has included more than twenty sailing craft, plus a variety of other watercraft.
A sailing hydrofoil, hydrofoil sailboat, or hydrosail is a sailboat with wing-like foils mounted under the hull. As the craft increases its speed the hydrofoils lift the hull up and out of the water, greatly reducing wetted area, resulting in decreased drag and increased speed. A sailing hydrofoil can achieve speeds exceeding double and in some cases triple the wind speed.
Phil Morrison is a British boat designer and racer rendered notable by the success of his many designs in many classes since 1967 as well as his own distinguished yacht racing career.
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."
A sailing yacht, is a leisure craft that uses sails as its primary means of propulsion. A yacht may be a sail or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies here to sailing vessels that have a cabin with amenities that accommodate overnight use. To be termed a "yacht", as opposed to a "boat", such a vessel is likely to be at least 33 feet (10 m) in length and have been judged to have good aesthetic qualities. Sailboats that do not accommodate overnight use or are smaller than 30 feet (9.1 m) are not universally called yachts. Sailing yachts in excess of 130 feet (40 m) are generally considered to be superyachts.

The Romandisea Titanic is an unfinished full-scale replica of the RMS Titanic, located in landlocked Sichuan province, China. The project was first reported in October 2013 and formally launched in January 2014. The ship was to be the same size as the original Olympic-class ocean liner Titanic. The replica vessel was anticipated to be the centerpiece of the Romandisea resort and would have included overnight hotel accommodations. It was to be permanently docked in a reservoir on the Qijang River, a tributary of the Fu River, at coordinates 30.6282°N 105.2220°E in Sichuan's rural Daying County.
