The trimaran configurations has also been used for both passenger ferries and warships. The Australian shipbuilding company, Austal, investigated the comparative merits of trimaran ships, catamarans and monohulls. It found that there was an optimum location for the outer hulls in terms of minimizing wave generation and consequent power ...
The relationship between monohulls & multihulls. A multihull is a boat or ship with more than one hull, whereas a vessel with a single hull is a monohull. The most common multihulls are catamarans (with two hulls), and trimarans (with three hulls). There are other types, with four or more hulls, but such examples are very rare and tend to be ...
Traditional sailboats are monohulls, but multi-hull catamarans and trimarans are gaining popularity. Monohull boats generally rely on ballast for stability and usually are displacement hulls. This stabilizing ballast can, in boats designed for racing, be as much as 50% of the weight of the boat, but is generally around 30%.
The following is a partial list of sailboat types and sailing classes, including keelboats, dinghies, and multihull (catamarans and trimarans). Olympic classes [ edit ]
Graphical representation of the dimensions used to describe a ship. Dimension "b" is the beam at waterline.. The beam of a ship is its width at its widest point. The maximum beam (B MAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H) only includes permanently fixed parts of the hull, and beam at waterline (B WL) is the maximum width where the ...
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.
Displacement hulls - Monohull boats frequently ride deeply in the water, this is known as a displacement hull. Planing hulls - Hulls that ride on top of the water are called planing hulls, because when they reach speed, the hulls are substantially lifted above the water; this is known as planing (to plane).
The first high-speed craft were often hydrofoils or hovercraft, but in the 1990s catamaran and monohull designs become more popular. Most high-speed craft serve as passenger ferries, but the largest catamarans and monohulls also carry cars, buses, large trucks and freight.
