Sail switch. A sail switch, vane switch or flow switch is a mechanical switch that is actuated on or off in response to the flow or non-flow of a fluid such as air or water. [1] A sail switch typically operates through the use of a paddle or a diaphragm which gets displaced due to the force of fluid or air moving past it.

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.

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.
Following his "doodle" Kirby developed working drawings that Ian Bruce used to develop the Laser. The plans stayed with Kirby and Bruce until 1970 when One Design and Offshore Yachtsman magazine held a regatta for boats under $1000, called "America's Teacup." After a few sail modifications, the Laser easily won its class.
Laser propulsion. 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 ...
