A Formula 16 beachable catamaran Powered catamaran passenger ferry at Salem, Massachusetts, United States. A catamaran (/ ˌ k æ t ə m ə ˈ r æ n /) (informally, a "cat") is a watercraft with two parallel hulls of equal size. The wide distance between a catamaran's hulls imparts stability through resistance to rolling and overturning; no ...
Sailing hydrofoils achieve boat speeds up to twice the speed of the wind, as did the AC72 catamarans used for the 2013 America's Cup. [20] Ice boats can sail up to five times the speed of the wind. [21] [22] Lateral force is a reaction supplied by the underwater shape of a sailboat, the blades of an ice boat and the wheels of a land sailing craft.
A catamaran is a vessel with twin hulls. Commercial catamarans began in 17th century England. Separate attempts at steam-powered catamarans were carried out by the middle of the 20th century. However, success required better materials and more developed hydrodynamic technologies. During the second half of the 20th century catamaran designs ...
The F50 is a one-design foiling catamaran used in the SailGP race series. The name is an abbreviation of "Foiling" and "a hull length of 50 feet". [1]The F50s are adapted from the AC50s used in the America's Cup, with modifications including new control systems and modular wingsails. [2]
The top of the wing of an Oracle AC45 racing catamaran. Wingsails are of two basic constructions that create an airfoil, "soft" and "hard", both mounted on an unstayed rotating mast. [4] Whereas hard wingsails are rigid structures that are stowed only upon removal from the boat, soft wingsails [5] [6] can be furled or stowed on board. [4]
The Tornado is among the fastest double handed catamarans, with an ISAF Small Catamaran Handicap Rating System rating of 0.934 and a D-PN of 59.0. [2] It is the fastest catamaran in the RYA Portsmouth Yardstick scheme, with a 2015 Portsmouth Number of 634.

A tunnel hull is a type of boat hull that uses two typically planing hulls with a solid centre that traps air. This entrapment then creates aerodynamic lift in addition to the planing (hydrodynamic) lift from the hulls.
