A design engineer by profession, Cross worked for Ford Motor Company, then spent 16 years with General Dynamics' Convair Division in their department of wind-tunnel model design and towing basin testing. [1]
Constant Camber 26 is a 26 ft (7.9 m) cruising sloop trimaran sailboat designed in the 1970s by John Marples featuring berths for two adults and two children. [1] [2] The constant camber hull is constructed using a single master template to produce each panel, resulting in a design with unchanging curvature, imparting extraordinary strength similar to an eggshell.
In January 1995 Sail magazine named the F-27 as one of several boat designs that "had a significant and positive impact on sailing over the past 25 years". [1] The F-27 was inducted into the American Sailboat Hall of Fame on 29 January 2004. [1] In 2016, Sailing magazine's technical editor Bob Perry described the F-27 as "a great boat". [9]
USA-17—a 90-foot-long (27 m) trimaran, type BOR90. A traditional paraw double-outrigger sailboat from the Philippines. A trimaran (or double-outrigger) is a multihull boat that comprises a main hull and two smaller outrigger hulls (or "floats") which are attached to the main hull with lateral beams.
The design concept comprises a narrow, long hull that cuts through waves. The outriggers then provide the stability that such a narrow hull needs. While the aft sponsons act as trimaran sponsons do, the front sponsons do not touch the water normally; only if the ship rolls to one side do they provide added buoyancy to correct the roll.
The vessel was designed by LOMOcean Design (formerly Craig Loomes Design Group Ltd.) and built by Calibre Boats in Auckland, New Zealand. [13] The wave-piercing trimaran design allowed for improved speed and stability. The boat was fully submersible, able to cut through 15-metre (49 ft) waves and go 7 m (23 ft) underwater. [2]
Jim Brown stayed with Piver's narrow-waisted hulls while introducing the centerboard, center cockpit, and cutter rig. Of the 47 multihulls we spoke outside U.S. waters, 13 were Brown designs. While poor payload capacity and hobby-horsing are owner complaints with the 31 and 37, his 40-footer gets high marks.
The Farrier F-24, also called the Corsair F-24, is an American trailerable trimaran that was designed by Ian Farrier as a racer-cruiser and first built in 1991. [1 ...
