World Sailing
World Sailing (WS) is the world governing body for the sport of sailing recognized by the International Olympic Committee and the International Paralympic Committee (IPC). History The creation of the International Yacht Racing Union (IYRU) began in 1904, when Major Brooke Heckstall-Smith AINA, then Secretary of the Yacht Racing Association (now the Royal Yachting Association) wrote to the Yacht Club de France, pointing out the desirability of holding a conference for the purpose of devising an International Rule of Measurement for Racing Yachts acceptable to all European countries. As a result, an International Conference of Yacht Measurement was held in London in January and June 1906, at which the Metre Rule was developed. This group went on to adopt a formal Constitution after a meeting at the Yacht Club de France in Paris on 14 October 1907 which is seen as the formation date of the International Yacht Racing Union. On 5 August 1996, the IYRU changed its name to the Interna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bowsprit
The bowsprit of a sailing vessel is a spar extending forward from the vessel's prow. The bowsprit is typically held down by a bobstay that counteracts the forces from the forestays. The word ''bowsprit'' is thought to originate from the Middle Low German word ''bōchsprēt'' – ''bōch'' meaning "bow" and ''sprēt'' meaning "pole". It is sometimes used to hold up the figurehead In politics, a figurehead is a person who ''de jure'' (in name or by law) appears to hold an important and often supremely powerful title or office, yet ''de facto'' (in reality) exercises little to no actual power. This usually means that they .... References References * {{Sailing ship elements Sailboat components ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asymmetrical Spinnaker
An asymmetrical spinnaker is a sail used when sailing downwind. Also known as an "asym", "aspin", or "A-sail" it can be described as a cross between a genoa jib and a spinnaker. It is asymmetric like a genoa, but, the asymmetrical spinnaker is not attached to the forestay over the full length of its luff, being rigged like a spinnaker. The asymmetrical spinnaker has a larger camber than a genoa, making it optimal for generating lift at larger angles of attack, but the camber is significantly less than that of a spinnaker. The asymmetrical spinnaker is a specialty sail used on racing boats, bridging the performance gap between a genoa, which develops maximum driving force when the apparent wind angle is between 35 and 60 degrees, and a spinnaker, which has maximum power when the apparent wind is between 100 and 140 degrees. Due to its geometry, the sail is less prone to collapsing than a spinnaker and does not require the use of spinnaker pole. The sail can benefit greatly and be ...

Sailor
A sailor, seaman, mariner, or seafarer is a person who works aboard a watercraft as part of its crew, and may work in any one of a number of different fields that are related to the operation and maintenance of a ship. The profession of the sailor is old, and the term ''sailor'' has its etymological roots in a time when sailing ships were the main mode of transport at sea, but it now refers to the personnel of all watercraft regardless of the mode of transport, and encompasses people who operate ships professionally, be it for a military navy or civilian merchant navy, as a sport or recreationally. In a navy, there may be further distinctions: ''sailor'' may refer to any member of the navy even if they are based on land; while ''seaman'' may refer to a specific enlisted rank. Professional mariners Seafarers hold a variety of professions and ranks, each of which carries unique responsibilities which are integral to the successful operation of an ocean-going vessel.

Boat Trailer
A boat trailer is designed to launch, retrieve, carry and sometimes store boats. Commercial boat trailers Commercial hydraulic boat trailers are used by marinas, boat yards, boat haulers, boat dealers and boat builders. Generally this type of trailer is not used for storage of the boat. Self-propelled Self-propelled boat movers are not strictly trailers, but hydraulically operated boat movers, with their own tractor unit. They share all of the features of hydraulic boat trailers. Non-commercial boat trailers This type of trailer is usually used by the boat owner/operator. The trailer is also used for storage. * Roll-on, also known as a "Roller style trailer", uses rubber and/or polyurethane rollers for ease of launching and loading a boat. * Glide-path, also known as a "Float-on style trailer", allows the boat to float onto the trailer; after the trailer has been partially submerged (usually of the trailer). Since its inception, it has become quite popular compared to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiller
A tiller or till is a lever used to steer a vehicle. The mechanism is primarily used in watercraft, where it is attached to an outboard motor, rudder post or stock to provide leverage in the form of torque for the helmsman to turn the rudder. A tiller may also be used in vehicles outside of water, and was seen in early automobiles. On vessels, a tiller can be used by the helmsman directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel. Rapid or excessive movement of the tiller results in an increase in drag and will result in braking or slowing the boat. Description A tiller is a lever used to steer a vehicle. It provides leverage in the form of torque to turn the device that changes the direction of the vehicle, such as a rudder on a watercraft or the surface wheels on a wheeled vehicle. A tiller can be used by directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel; some kayaks wh ...

Reverse Transom
A transom is the vertical reinforcement which strengthens the stern of a boat. This flat termination of the stern is typically above the waterline. The term was used as far back as Middle English in the 1300s, having come from Latin ''transversus'' (transverse) via Old French ''traversain'' (set crosswise). The stern of a boat is typically vertical. It can be raked such that there is an overhang above the water, as at the bow. A reverse transom is angled from the waterline forwards. Transoms can be used to support a rudder, outboard motor, or as a swimming and access platform.

Plumb Stem
The stem is the most forward part of a boat or ship's bow and is an extension of the keel itself. It is often found on wooden boats or ships, but not exclusively. Description The stem is the curved edge stretching from the keel below, up to the gunwale of the boat. It is part of the physical structure of a wooden boat or ship that gives it strength at the critical section of the structure, bringing together the port and starboard side planks of the hull. Plumb and raked stem There are two styles of stems: ''plumb'' and ''raked''. When the stem comes up from the water, if it is perpendicular to the waterline it is "plumb". If it is inclined at an angle to the waterline it is "raked". (For example, "The hull is single decked and characterized by a plumb stem, full bows, straight keel, moderate deadrise, and an easy turn of bilge.") Stemhead Because the stem is very sturdy, the top end of it may have something attached, either ornamental or functional in nature. On smalle ...

Roller Furling
Roller furling is a method of furling (i.e. reefing) a yacht's staysail by rolling the sail around a stay. Roller furling is typically used for foresails such as jibs or genoas. A mainsail may also be furled by a similar system, whereby the sail is furled within the mast or around a rotating boom (or around a rotating shaft within a boom). Although staysail roller-furling is effective and very common, in-mast or in-boom mainsail furling involves some compromises, and mainsail slab reefing gives a better sail shape. Methods The idea for a furling jib is usually attributed to Major E du Boulay in England who invented a device similar to a roller blind for reefing a jib. Major Wykeham-Martin used one of Boulay's rollers and improved the system by incorporating roller bearings in 1907 when the system was patented. The original castings were made by London-based toilet makers Bouldings. By the 1940s nearly every British cruising yacht was fitted with this furling system. An early v ...

Fractional Rig
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 forestay is a wire that secures the mast to the front of the boat. With a fractional rig, the forestay is attached between about 1/8 and 1/4 of the length of the mast lower down, rather than being attached to the top of the mast as in a masthead rig. The foresail (jib or genoa) is then rigged to this stay. The mast is farther forward on the boat than on a masthead rig and so it has a larger mainsail. Masthead rigs are most common on larger keelboats or cruisers. A fractional rig is typically used on sailing dinghies and racing oriented keelboats, such as the J/24. Fractional rigs were introduced on race boats in order to allow more controllability of the surface of the mainsail and also less drag when sailing upwind. According to one manufacturer, "a key to making fast boats easier to sail than slow boats is the 'fractional rig' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keelboat
A keelboat is a riverine cargo-capable working boat, or a small- to mid-sized recreational sailing yacht. The boats in the first category have shallow structural keels, and are nearly flat-bottomed and often used leeboards if forced in open water, while modern recreational keelboats have prominent fixed fin keels, and considerable draft. The two terms may draw from cognate words with different final meaning. A keep boat, keelboat, or keel-boat is a type of usually long, narrow cigar-shaped riverboat, or unsheltered water barge which is sometimes also called a poleboat—that is built about a slight keel and is designed as a boat built for the navigation of rivers, shallow lakes, and sometimes canals that were commonly used in America including use in great numbers by settlers making their way west in the century-plus of wide-open western American frontiers. They were also used extensively for transporting cargo to market, and for exploration and trading expeditions, for wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
