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:
The Albacore is a 4.57 m (15 ft) two-person planing dinghy with fractional sloop rig, for competitive racing and lake and near-inshore day sailing. Hulls are made of either wood or fiberglass. The basic shape was developed in 1954 from an Uffa Fox design, the Swordfish. Recent boats retain the same classic dimensions, and use modern materials and modern control systems.
The Topper is an 11 foot 43 kg (95 lb) sailing dinghy designed by Ian Proctor. The Topper was a one-design boat until 2023 when a new version was produced, and is sailed mostly around the British Isles. It was recognised as a World Sailing Class. The boat previously constructed from polypropylene, and now roto moulded, is popular as a racing boat or for sail training. The class association (ITCA) organise racing events, which range from small travellers to major championships. The RYA run squads alongside the events; in these squads young sailors who are given specialist race coaching.
The GP14 is a wooden or fibreglass hulled double-handed fractional Bermuda rigged sailing dinghy designed by Jack Holt in 1949.
The Wayfarer is a wooden or fibreglass hulled fractional Bermuda rigged sailing dinghy of great versatility; used for short 'day boat' trips, longer cruises and for racing. Over 11,000 have been produced as of 2016.
A Squib is a type of small racing keelboat designed in 1967 by Oliver Lee as a successor to the Ajax 23. It is a strict "one-design" class of boat, having a length of 19', beam of 6'1½", a sail area of 170 sq. ft. upwind, 310 sq. ft. total and a weight of 1500 lb (680 kg). The usual crew is two people and the boat can be cruised or raced with a Portsmouth Yardstick of 1142. The Squib has been adopted by the RYA as the National Keelboat and is big enough to race at sea and small enough to be trailed easily behind a family car.
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.
A Bermuda rig, Bermudian rig, or Marconi rig is a configuration of mast and rigging for a type of sailboat and is the typical configuration for most modern sailboats. This configuration was developed in Bermuda in the 17th century; the term Marconi, a reference to the inventor of the radio, Guglielmo Marconi, became associated with this configuration in the early 20th century, because the wires that stabilize the mast of a Bermuda rig reminded observers of the wires on early radio masts.
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 long, with a waterline length of 3.81 m. The hull weight is 59 kg (130 lb). The boat is manufactured by ILCA and World Sailing approved builders.
The International 420 Dinghy is a sailing dinghy popular for racing and teaching. The hull is fiberglass with internal buoyancy tanks. The 420 has a bermuda rig, spinnaker and trapeze. It has a large sail-area-to-weight ratio, and is designed to plane easily. The 420 is an International class recognised by World Sailing. The name refers to the boat's length of 420 centimetres.
The OK Dinghy is an international class sailing dinghy, designed by Knud Olsen in 1956.
A fractional rig on a sailing vessel consists of a foresail, such as a jib or genoa sail, that does not reach all the way to the top of the mast.
The Shannon One Design sailing dinghy is an open centreboard sailing boat raced on the River Shannon, Lough Derg and Lough Ree in Ireland. The boats are 18 feet (5.5 m) long by 4 feet 10.5 inches (1.486 m) beam, drawing 4 feet (1.2 m) with her centreboard down. They have a sail area of 140 square feet (15.6m2) set in a single sail, giving the boat what is called a gunter rig.
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 Twelve Foot Dinghy was designed by George Cockshott, an amateur boat designer from Southport, England in response to a 1912 design contest. It became the first one-design racing dinghy to achieve international recognition. The class was granted the 'International' status by the IYRU in 1919 and remained this status until 1964 when it was revoked by the same authority. The class was selected as the dinghy class for the Olympics in 1920 & 1928. In 1924 the French wanted to use an alternate French design.
Lough Derg Yacht Club is a boat club based in the lakeside village of Dromineer in County Tipperary, Ireland. Founded in 1835, it is one of the world's oldest yacht clubs. The club is based in a modern clubhouse on the east shore of Lough Derg.
