A useful analogy to solar sailing may be a sailing boat; the light exerting a force on the large surface is akin to a sail being blown by the wind. 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.
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.
Laser Pico. 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 ...

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.
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).
470 (dinghy) The 470 (Four-Seventy) is a double-handed monohull planing dinghy with a centreboard, Bermuda rig, and centre sheeting. Equipped with a spinnaker, trapeze and a large sail-area-to-weight ratio, it is designed to plane easily, and good teamwork is necessary to sail it well. The name comes from the boat's length of 470 centimetres (4 ...
A laser-pushed lightsail is a thin reflective sail similar to a solar sail, in which the sail is being pushed by a laser, rather than the sun. The advantage of lightsail propulsion is that the vehicle does not carry either the energy source or the reaction mass for propulsion, and hence the limitations of the Tsiolkovsky rocket equation to ...
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.
Solar-pumped laser. A solar-pumped laser (or solar-powered laser) is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent electromagnetic radiation which can reach high power, but which uses solar radiation for pumping the lasing medium. This type of laser is unique from other ...
