A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture.
Dinghy sailing is the activity of sailing small boats by using five essential controls:
Dinghy racing is a competitive sport using dinghies, which are small boats which may be rowboats, have an outboard motor, or be sailing dinghies. Dinghy racing has affected aspects of the modern sailing dinghy, including hull design, sail materials and sailplan, and techniques such as planing and trapezing.
The Laser is a widely used 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. Bruce Kirby designed the Laser in 1970 with an emphasis on simplicity and performance.
The Optimist, also known as the ‘opti’, or 'oppie', is a small, single-handed sailing dinghy intended for use by children and teenagers up to the age of 15. Contemporary boats are usually made of fibreglass, although wooden boats are still built.
Planing is the mode of operation for a waterborne craft in which its weight is predominantly supported by hydrodynamic lift, rather than hydrostatic lift (buoyancy).
The 49er and 49er FX is a two-handed skiff-type high-performance sailing dinghy. The two crew work on different roles with the helm making many tactical decisions, as well as steering, and the crew doing most of the sail control. Both of the crew are equipped with their own trapeze and sailing is done while cantilevered over the water to the fullest extent to balance against the sails.
In sailing, hiking is the action of moving the crew's body weight as far to windward (upwind) as possible, in order to decrease the extent the boat heels. By moving the crew's weight to windward, the moment of that force around the boat's center of buoyancy is increased. This opposes the heeling moment of the wind pushing sideways against the boat's sails. It is usually done by leaning over the edge of the boat as it heels. Some boats are fitted with equipment such as hiking straps and trapezes to make hiking more effective.
The Laser 4000 is a racing dinghy designed by Phil Morrison 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 Tasar is a 14.83-foot (4.52 m) fiberglass 2 person sailing dinghy with a mainsail and jib. Designed by Frank Bethwaite of Sydney in 1975, the boat was technologically advanced for its time and continues to evolve. Aimed at a husband-and-wife or parent-and-child crew hence no spinnaker, it is designed for a combined crew weight of around 140 kg. The hull weighs 68 kg, and is of sandwich foam construction. The hull has a fine angle at the bow to reduce wave impact drag with unusually clean and sharp chines aft to ensure very free planing and outstanding stability. The foam cored hull is stiff and light and the advanced hull shape, together with an innovative rig which combines a rotating mast with a fully battened main sail, allows the Tasar to plane upwind with the crew normally hiked. The wide beam and a cockpit designed for comfortable hiking make the Tasar easy, fun and very exciting to sail in winds up to 25 knots (46 km/h).
The 18 ft Skiff is considered the fastest class of sailing skiffs. The class has a long history beginning with races on Sydney Harbour, Australia in 1892 and later in New Zealand. The boat has changed significantly since the early days, bringing in new technology as it became available. Because of the need of strength, agility and skill, the class is considered to be the top level of small boat sailing. Worldwide this boat is called the "18 Foot Skiff". It is the fastest conventional non-foiling monohull on the yardstick rating, with a score of 675, coming only third after the Tornado and Inter 20.
The International 14 is a 14-foot double-handed racing dinghy. The class originated in England in the early part of the 20th century. It is sailed and raced in many countries around the world and was one of the first true international racing dinghy classes recognised by International Sailing Federation. It is a development class, being controlled by a set of rules that allow for innovation and changes in hull and rig design as long as they fall within a set of specific limitations such as length, weight, beam, and sail area. The class has permitted its rules to be revised at various times in its history in order to keep the class at the forefront of dinghy racing development and can now best be described as an ultralight dual-trapeze sailing dinghy with large sail area. It is often raced with boats of similar design in one-design, or non-handicap races.
The Moth is a small development class of sailing dinghy. Originally a small, fast home-built sailing boat designed to plane, since 2000 it has become an expensive and largely commercially-produced boat designed to hydroplane on foils.
The Cherub is a 12 feet long, high performance, two-person, planing dinghy first designed in 1951 in New Zealand by John Spencer. The class is a development class, allowing for significant variation in design between different boats within the rule framework. The minimum hull weight was originally 110 lbs.
A mast-aft rig is a sailboat sail-plan that uses a single mast set in the aft half of the hull. The mast supports fore-sails that may consist of a single jib, multiple staysails, or a crab claw sail. The mainsail is either small or completely absent. Mast-aft rigs are uncommon, but are found on a few custom, and production sailboats.
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 premium proprietary sources and replacing the symmetric spinnaker of the Laser 2 by a larger asymmetrical spinnaker. The gennaker is chute-launched and retrieved using a single halyard line, and is set on a retractable bowsprit. Helm balance and handling were improved using a shorter-footed mainsail with two full-width battens giving a larger roach. A mast with conventional spreaders replaced the now-unusual diamond arrangement of the Laser 2.

The Jacksnipe is a two-man racing sailing dinghy with a single trapeze for the crew and symmetrical spinnaker.
The Bermuda Fitted Dinghy is a type of racing-dedicated sail boat used for competitions between the yacht clubs of Bermuda. Although the class has only existed for about 130 years, the boats are a continuance of a tradition of boat and ship design in Bermuda that stretches back to the earliest decades of the 17th century.
The Esse 850 is an 8.5 metre long racing sportboat designed by Umberto Felci and built by Josef Schuchter Sportboats of Stafa, Switzerland. The first hull was sold in 2004 and the Esse 850 International Class Association was begun in 2005 in Europe.
