A small waterplane area twin hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea , where wave energy is located, minimizes a vessel's response to sea state, even in high seas and at high speeds.
The Lagoon 55 catamaran is a large ocean-going sailing catamaran that was designed by VPLP (a French based naval architecture firm founded by Marc Van Peteghem and Vincent Lauriot-Prévost). First built in France in 1987, it was one of the earliest large production cruising catamarans available both for private owners and for the yacht charter ...
The boat has a draft of 3.67 ft (1.12 m) with the centerboard extended and 4 in (10 cm) with it retracted, allowing beaching or ground transportation on a trailer. [1] For sailing the design is equipped with hiking straps, a trapeze, an outhaul, boom vang, a high-mounted boom and a mainsheet traveler. It has a storage compartment under the ...
The Spirit of Dallas catamaran on White Rock Lake 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 ...
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 ...
Theoretical research and full-scale testing of tunnel hulls has demonstrated the dramatic contributions of 'close-proximity ground effect' on enhanced aerodynamic lift/drag in operation of performance tunnel hull designs. [1] Tunnel hulls are distinguishable from other catamarans by the typical close hull spacing and solid deck in between the ...
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 design was built by the Lagoon catamaran division of Jeanneau in France and was the smallest catamaran in their product line. The division was later sold to Construction Navale Bordeaux (CNB) which became part of Groupe Beneteau. Production started in 1999 and the improved Lagoon 380 S2 model was introduced in 2003.
