Laser 3000. The Laser 3000 is a racing sailing dinghy crewed by two persons with a trapeze for the crew. Launched in 1996, the 3000 was developed from the Laser 2, using the original Frank Bethwaite -designed planing hull combined with a brand new self-draining deck by Derek Clark. Clark also re-designed the rig, using spars and sails from ...
The Laser Pico dinghy is a small sailboat designed by Jo Richards in the mid-1990s [1] and used primarily for training and day sailing. It can be crewed by one or two children or an adult. Current models come equipped with both a mainsail and a jib, the jib however mainly functions as a training tool and provides little to no contribution to speed.
LaserPerformance now builds and sells a wide range of racing and recreational sailboat dinghies, including the Laser, Laser Pico, Laser Bahia, Laser Vago, Sunfish, Club FJ, Club 420, Dart 16, and Bug. As of summer 2021, LaserPerformance remains in negotiations with the ILCA and has not signed a Builder's Agreement for Laser dinghies.
High-energy laser beams could be used as an alternative light source to exert much greater force than would be possible using sunlight, a concept known as beam sailing. Solar sail craft offer the possibility of low-cost operations combined with high speeds (relative to chemical rockets) and long operating lifetimes. Since they have few moving ...
2000 (dinghy) The 2000 (formerly the Laser 2000) is a performance sailing dinghy designed by Phil Morrison and currently sold by RS Sailing. It combines a traditional GRP hull and foam sandwich deck moulding with a modern asymmetric rig including a furling jib, reefing mainsail and single line gennaker hoist system.
Laser (dinghy) The Laser is a class of single-handed, one-design sailing dinghies using a common hull design with three interchangeable rigs of different sail areas, appropriate to a given combination of wind strength and crew weight. Ian Bruce and Bruce Kirby designed the Laser in 1970 with an emphasis on simplicity and performance.
95.4 [1] RYA PN. 1175 [2] [ edit on Wikidata] The Laser 4.7 or ILCA 4 is a one-design dinghy class in the Laser series and is a one-design class of sailboat. All Lasers are built to the same specifications. The Laser is 4.06 m (13 ft 10 in) long, with a waterline length of 3.81 m (12 ft 6 in). The hull weight is 59 kg (130 lb).
Laser propulsion is a form of beam-powered propulsion where the energy source is a remote (usually ground-based) laser system and separate from the reaction mass. This form of propulsion differs from a conventional chemical rocket where both energy and reaction mass come from the solid or liquid propellants carried on board the vehicle.
High-performance sailing. High-performance sailing is achieved with low forward surface resistance—encountered by catamarans, sailing hydrofoils, iceboats or land sailing craft—as the sailing craft obtains motive power with its sails or aerofoils at speeds that are often faster than the wind on both upwind and downwind points of sail ...
The free-electron laser FELIX Radboud University, Netherlands. A free-electron laser ( FEL) is a fourth generation light source producing extremely brilliant and short pulses of radiation. An FEL functions much as a laser but employs relativistic electrons as a gain medium instead of using stimulated emission from atomic or molecular excitations.
