The Laser 4000 is a well known racing dinghy crewed by two persons. Its one-design weight-equalised system enables physically differing sailors to compete on a level playing field. It is most popular in Europe, particularly the UK, France and Italy. The 4000 is a fast, planing skiff-style dinghy with a trapeze for the crew and trampolines for the helm. Upwind, the boat does not point especially close to the wind, but its fully battened sails give enough power to keep up with similar-sized boats. Downwind, however is where the boat excels due to its asymmetric spinnaker (aka gennaker). In a force 3 the 4000 will plane and the crew will make full use of the trapeze wire. However, force 4-5 is when the boat performs its optimum. The 4000 is fast enough to make use of the apparent wind to reach the bottom of the racecourse sooner. In lighter winds, many crews make use of the jibing gennaker pole when sailing downwind. This allows them to show a larger part of the spinnaker to the wind whilst sailing further away from the wind direction. ==Features== The Laser 4000 was designed in 1994 by yacht designer Phil Morrison. It is a sloop rigged dinghy constructed from fiberglass. It features a single trapeze as well as an open, self-draining cockpit. Instead of a conventional kicking strap it features a gnav system, which pushes down on the boom from the top, instead of pulling from the bottom. This allows greater space for the crew to move from side to side. Boat manufacture is well known to be of a very high quality and durability, thus hulls from the very first molds are still competing effectively. However recently Laser has handed over the rules and administration of the class to the Laser 4000 class association and thus there is significant scope for boat improvement. Many people want to see the addition of carbon spars and lighter hulls (nickname = 4 tonner!). However the class is adamant that it will stay a one class design and not a class open to unlimited modification such as the International 14 class. 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「Laser 4000」の詳細全文を読む スポンサード リンク
