A yacht is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a yacht, as opposed to a boat, such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities.
A catamaran is a watercraft with two parallel hulls of equal size. The distance between a catamaran's hulls imparts resistance to rolling and overturning. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes.
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 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.
Hobie Cat is a company that manufactures sailing catamarans, surfboards, sailboats, kayaks, stand-up paddle boards, and pedalboards as the Hobie Cat Company. It was founded in 1961 by Hobart Alter, who originally manufactured surfboards. Its line of products has included more than twenty sailing craft, plus a variety of other watercraft.
The Laser 4000(now "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 A-Class Catamaran, often abbreviated to A-Cat, is a development class sailing catamaran for singlehanded racing.
The term beachcat is an informal name for one of the most common types of small recreational sailboats, minimalist 14 to 20 foot catamarans, almost always with a cloth "trampoline" stretched between the two hulls, typically made of fiberglass or more recently rotomolded plastic. The name comes from the fact that they are designed to be sailed directly off a sand beach, unlike most other small boats which are launched from a ramp. The average 8 foot width of the beachcat means it can also sit upright on the sand and is quite stable in this position, unlike a monohull of the same size. The Hobie 14 and Hobie 16 are two of the earliest boats of this type that achieved widespread popularity, and popularized the term as well as created the template for this type of boat.
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 Catamaran Challenge Trophy is the formal name for the match racing series between two catamarans familiarly known the Little Americas Cup. While a championship series sailed between C Class catamarans does still exist, it is no longer known as the Little America's Cup.
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.
A sailing yacht, is a leisure craft that uses sails as its primary means of propulsion. A yacht may be a sail or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies here to sailing vessels that have a cabin with amenities that accommodate overnight use. To be termed a "yacht", as opposed to a "boat", such a vessel is likely to be at least 33 feet (10 m) in length and have been judged to have good aesthetic qualities. Sailboats that do not accommodate overnight use or are smaller than 30 feet (9.1 m) are not universally called yachts. Sailing yachts in excess of 130 feet (40 m) are generally considered to be superyachts.
The term sportsboat first appeared in the late 1980s and early 1990s to describe trailer sailers that were optimised for high performance at the expense of accommodation and ballast. The very definition of the term "sportsboat" is evolving.
The Topcat is a one-design sailing catamaran boat class which is divided into several boat sizes.
The Splash Dinghy is 3.5 m in length and all boats are identical, thus, as is typical in One-Design classes, the sailor's ability rather than equipment is emphasised fleet racing. The boats employ an un-stayed mono rig with a sail area of 6.3 m2, which makes the class easy to handle by sailors ranging from 45 to 80 kg. This, combined with the low hull weight of 55 kg, allow the class to serve as a stepping stone between the Optimist Dinghy and boats such as the Laser Radial, suiting sailors in the age range from 13 to 21 years.
The RS Tera is a one-man monohull dinghy in the RS Sailing range of sailing boats. It is recognised by the International Sailing Federation (ISAF) as an international class, and is a popular boat for beginners and for children to race.
James Wharram was a British multihull pioneer and designer of catamarans.
The Nacra 17 is a performance catamaran used for sailing. It was designed in 2011, went into production in 2012 and has been the focus of multihull sailing at the Olympic Games since its conception.
The M32 is a class of sailing catamaran designed by Göran Marström and Kåre Ljung and first built in 2010 by Marstrom Composite AB. The design and production rights were sold in 2013 to Aston Harald Composite AB led by Håkan Svensson and run by Killian Bushe.
