The Sturgeon class was a class of nuclear-powered fast attack submarines (SSN) in service with the United States Navy from the 1960s until 2004. They were the "workhorses" of the Navy's attack submarine fleet throughout much of the Cold War. The boats were phased out in the 1990s and early 21st century, as their successors, the Los Angeles, followed by the Seawolf and Virginia-class boats, entered service.
A dinghy is a type of small boat, often carried or towed by a larger vessel for use as a tender. Utility dinghies are usually rowboats or have an outboard motor. Some are rigged for sailing but they differ from sailing dinghies, which are designed first and foremost for sailing. A dinghy's main use is for transfers from larger boats, especially when the larger boat cannot dock at a suitably-sized port or marina.
Dinghy sailing is the activity of sailing small boats by using five essential controls:
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; it can be used for short 'day boat' trips, for longer cruises and for racing. Over 11,000 have been produced as of 2016.
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.
The Royal Navy's T class of diesel-electric submarines was designed in the 1930s to replace the O, P, and R classes. Fifty-three members of the class were built just before and during the Second World War, where they played a major role in the Royal Navy's submarine operations. Four boats in service with the Royal Netherlands Navy were known as the Zwaardvisch class.
An iceboat is a recreational or competition sailing craft supported on metal runners for traveling over ice. One of the runners is steerable. Originally, such craft were boats with a support structure, riding on the runners and steered with a rear blade, as with a conventional rudder. As iceboats evolved, the structure became a frame with a seat or cockpit for the iceboat sailor, resting on runners. Steering was shifted to the front.
The Sunfish is a personal-size, beach-launched sailing dinghy. It features a very flat, boardlike hull carrying an Oceanic lateen sail mounted to an un-stayed mast.
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 movement 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.
Hobie Cat is a company that manufactures watercraft and other products as the Hobie Cat Company. "Hobie Cat" can also refer to specific products of the company, notably its sailing catamarans. Its fiberglass catamaran models range in nominal length between 14 feet (4.3 m) and 18 feet (5.5 m). Rotomolded catamaran models range in length between 12 feet (3.7 m) and 17 feet (5.2 m). Other sailing vessels in the Hobie Cat lineup include, monocats, dinghies, and trimarans, ranging in length between 9 feet (2.7 m) and 20 feet (6.1 m). Its largest product was the Hobie 33, 33 feet (10 m) in length. The company's non-sailing product line includes surfboards, kayaks, stand-up paddle boards, pedalboards, eyeware, and e-bikes. It was founded in 1961 by Hobart (Hobie) Alter, who originally manufactured surfboards.
The Fireball is a British sailing dinghy that was designed by Peter Milne as a one-design racer and first built in 1962.
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.
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 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.
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 Norfolk Punt is a high-performance sailing dinghy designed for sailing on the Norfolk Broads.
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.
