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 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 boat initially was designed to displace 315 lb (143 kg) and can be equipped with a trapeze. [ 1 ] [ 2 ] [ 3 ] The design has a draft of 1.50 ft (0.46 m) with the centerboard extended and 0.42 ft (0.13 m) with it retracted, allowing beaching or ground transportation on a trailer .
The official organisation for the A-Class catamaran is the IACA (International A division Catamarans Association). The A-Class rules were expanded over time to prevent the cost of these boats from rising too high and to ensure fairness in racing. Currently the main A-Class rules are: [3] Min overall boat weight : 75 kg / 165.3 lbs
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 Prindle 18 is an American catamaran sailing dinghy that was designed by Geoffrey Prindle as a racer and first built in 1977. [1] [2] [3]Geoffrey Prindle had started out as a surfboard manufacturer but was also successful racing Hobie 14 catamarans and started his own line of boats, starting with the Prindle 16.
The Cracksman 20 is an early fibreglass-hulled Fractional rigged sloop sailing catamaran used for 'day boat' trips and longer cruises. Designed by Michael Henderson in the early 1960s and built by Newbridge Boats Ltd from 1963, the boat's shallow draft (when sailing) of less than three feet allows the boat to sail with versatility in even the shallowest of waters.
Since no existing design or class fit the ISAF specs, we decided to create an all-new design that is about 17 feet long, called the NACRA 17. Compared to an F16 class catamaran, it is 250mm longer, 100mm wider, has a taller mast and more sail area, and curved dagger boards. The curved boards also give an added dimension to the sailing.
