The B&R 23 is a sailing boat designed in the early 1990s. It has an ultralight construction with a very large sail plane. Typical crew is a helmsman and two deck hands in trapezes. The boat is predominately used for racing. == History == B&R 23 was designed by Lars Bergström, Sven-Olov Ridder and Torkel Stillefors. The idea came from Stillefors, who had been involved in the sail racing circles of New Zealand while living there in the early 1980s. During his time in New Zealand, Stillefors was inspired by the high performance extreme dinghies and ultra light displacement sport boats there. In addition, the 18ft skiffs in Sydney Harbour were a source of inspiration, and soon Stillefors started contemplate building something similar that could offer similar performance and thrills. Back in Sweden Stillefors got in contact with Lars Bergström and Sven-Olof Ridder, at the time a famous Swedish inventor/design duo, who became interested in Stillefors’ ideas for a new high performance sports boat. This lead them to taking part in the design of a new boat, the B&R 23. Bergström designed the hull and sail plan at his design office in Sarasota Florida, resulting in a computer printed line drawing, a design technique that was not common practice in those early days of computer-aided design. Ridder focused on the design of the hydrodynamic detail. Ridder, working as Professor at the Royal Institute of Technology in Stockholm, had previously built scaled models, very similar to the B&R 23, and performed dynamic tank testing on them to verify the hydrodynamic characteristics of the design. At his residence in Stockholm he designed the 32 degree swept back retractable keel and the rudder. Stillefors took charge of the superstructure, deck layout and equipment design. In 1993 the first B&R 23 was built at Bergsviksvarvet in Stockholm by Stillefors, and soon the sailors on Lake Mälaren saw a futuristic fast boat with two deck hands on wire swishing past them with water spraying around the bow. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「B&R 23」の詳細全文を読む スポンサード リンク
