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 ...
Even-numbered U.S. Navy littoral combat ships are built using the Independence-class trimaran design, while odd-numbered ships are based on a competing design, the conventional monohull Freedom-class littoral combat ship. [7] The initial order of littoral combat ships involved a total of four ships, including two of the Independence-class ...
A monohull's keel is made effective by a combination of weight, depth, and length. Sailing yacht with a fin keel. Most modern monohull boats have fin keels, which are heavy and deep, but short in relation to the hull length. More traditional yachts carried a full keel which is generally half or more of the length of the boat.
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).
Triton was designed as a demonstrator to prove that the trimaran concept would work successfully in a large warship. Following her launch in 2000, the ship began an extensive series of trials in 2001, which covered general ship handling, performance, sea-keeping behaviour, but also areas more specific to its design for which the Royal Navy had ...
The high-speed cruise ship project evolved into Austal's commercial high-speed trimaran ferry HSC Benchijigua Express. [5] The ships are 127.4 m (418 ft) long, with a beam of 31.6 m (104 ft), and a draft of 13 ft (3.96 m). [5] Their displacement is rated at 2,377 tons light, 3,228 tons full, and 851 tons deadweight.

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.
