Admiralty Sailing Craft
The ASC or Admiralty Sailing Craft (sometimes incorrectly called Admiralty Sea Cadet) is a purpose-built, rugged GRP or wood sailing dinghy, historically with gunter rig, with a Bermuda rig optional, designed for use by UK naval and sea cadet establishments as a pulling or sailing dinghy. It is a substantial craft, usually left on a mooring in quiet waters rather than being slipway launched. It is intended for a total crew of up to 8 although it can be sculled single-handed. It has a heavy metal centreplate, and is equipped for pulling in addition to sailing. There is also a sculling notch on the transom Transom may refer to: * Transom (architecture), a bar of wood or stone across the top of a door or window, or the window above such a bar * Transom (nautical), that part of the stern of a vessel where the two sides of its hull meet * Operation Tran .... This type of boat is gradually being phased out of the Sea Cadets due to the production of the new Trinity 500 rowing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass-reinforced Plastic
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sailing Dinghy
Dinghy sailing is the activity of sailing small boats by using five essential controls: * the sails * the foils (i.e. the daggerboard or centreboard and rudder and sometimes lifting foils as found on the Moth) * the trim (forward/rear angle of the boat in the water) * side-to-side balance of the dinghy by hiking or movement of the crew, particularly in windy weather ("move fast or swim") * the choice of route (in terms of existing and anticipated wind shifts, possible obstacles, other water traffic, currents, tides etc.) When racing, the above skills need to be refined and additional skills and techniques learned, such as the application of the "racing rules of sailing", boat handling skills when starting and when rounding marks, and knowledge of tactics and strategy. Racing tactics include positioning the boat at different angles. To improve speed when racing, sailors should position themselves at the windward direction (closest to the direction of the wind) in order to get "cl ...

Gunter Rig
Gunter rig is a configuration of sail and spars used in sailing. It is a fore and aft sail set abaft (behind) the mast. The lower half of the luff (front) of the sail is attached to the mast, and the upper half is fastened to a spar which is approximately vertical and reaches above the top of the mast. This spar is called a "yard", but it is common for some to confuse it with a "gaff" (as in gaff rig). The overall shape of a gunter sail is roughly triangular, so having a superficial resemblance to Bermuda rig. A gunter sail may also be called a "gunter lug" - a name which suggests developmental origins from increasing the angle of a high peaked standing lug. Gunter sails are sometimes described as "sliding gunter". Gunter rig is generally used in small sailing craft. One important advantage is that the shorter mast used with this rig usually fits within the hull when unstepped, together with the boom and yard. This is helpful for a dinghy that is towed behind a car, stored in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bermuda Rig
A Bermuda rig, Bermudian rig, or Marconi rig is a configuration of Mast (sailing), 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 1600s; the term ''Marconi'', a reference to the inventor of the Radio#History, radio, Guglielmo Marconi, became associated with this configuration in the early 1900s because the wires that stabilize the mast of a Bermuda rig reminded observers of the wires on early radio masts. Description The rig consists of a triangular sail set aft of the mast with its Mainsail#Bermuda rig, mainsail raised to the top of the mast; its parts of a sail, luff runs down the mast and is normally attached to it for its entire length; its Tack (sailing), tack is attached at the base of the mast; its Parts of a sail, foot (in modern versions of the rig) controlled by a Boom (sailing), boom; and its Parts of a sail, clew attached to the aft end of the boom, which is control ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Cadet Corps (United Kingdom)
The Sea Cadet Corps is a national youth charity, working with 15,000 young people between 10 and 18 years old across the UK. It has over 400 units across England, Scotland, Wales, Northern Ireland, Malta and Bermuda all run by 9,000 volunteers. Cadets follow a similar ethos, training plan, and rank structure, to the Royal Navy, and are recognised by the UK Ministry of Defence. History In 1854 a Vicar in Whitstable, Kent, returning from the Crimean War noticed many local orphans on the street, he set up an orphanage encouraging sailors to form a group to help them. This led to multiple other orphanages being set up across the country. Back then the organisation was known as the Naval Lads' Brigade with sailors teaching orphans nautical skills to help them find careers in the future. Gaining recognition, in 1899 Queen Victoria presented £10 (around £1,000 today) to the Windsor Unit to purchase uniforms. The Navy League in 1910 sponsored a small number of units as the Nav ...

Watercraft Rowing
Rowing is the act of propelling a human-powered watercraft using the sweeping motions of oars to displace water and generate reactional propulsion. Rowing is functionally similar to paddling, but rowing requires oars to be mechanically attached to the boat, and the rower drives the oar like a lever, exerting force in the ''same'' direction as the boat's travel; while paddles are completely hand-held and have no attachment to the boat, and are driven like a cantilever, exerting force ''opposite'' to the intended direction of the boat. In some strict terminologies, using oars for propulsion may be termed either "pulling" or "rowing", with different definitions for each. Where these strict terminologies are used, the definitions are reversed depending on the context. On saltwater a "pulling boat" has each person working one oar on one side, alternating port and starboard along the length of the boat; whilst "rowing" means each person operates two oars, one on each side of the b ...

Mooring (watercraft)
A mooring is any permanent structure to which a vessel may be secured. Examples include quays, wharfs, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. An ''anchor mooring'' fixes a vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore. As a verb, ''mooring'' refers to the act of attaching a vessel to a mooring. The term likely stems from the Dutch verb ''meren'' (to ''moor''), used in English since the end of the 15th century. Permanent anchor mooring These moorings are used instead of temporary anchors because they have considerably more holding power, for example because of lesser damage to the marine environment, and are convenient. Where there is a row of moorings they are termed a tier. They are also occasionally used to hold floating docks in place. There are several kinds of moorings: Swing moorings Swing moorings also known a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slipway
A slipway, also known as boat ramp or launch or boat deployer, is a ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage. The nautical terms ways and skids are alternative names for slipway. A ship undergoing construction in a shipyard is said to be ''on the ways''. If a ship is scrapped there, she is said to be ''broken up in the ways''. As the word "slip" implies, the ships or boats are moved over the ramp, by way of crane or fork lift. Prior to the move the vessel's hull is coated with grease, which then allows the ship or boat to "slip" off of the ramp and progress safely into the water. Slipways are used to launch (newly built) large ships, but can only dry-dock or repair smaller ships. Pulling large ships against the greased ramp would require too much force. Therefor ...

Centreboard
A centreboard or centerboard (US) is a retractable hull appendage which pivots out of a slot in the hull of a sailboat, known as a ''centreboard trunk'' (UK) or ''centerboard case'' (US). The retractability allows the centreboard to be raised to operate in shallow waters, to move the centre of lateral resistance (offsetting changes to the sailplan that move the centre of effort aft), to reduce drag when the full area of the centreboard is not needed, or when removing the boat from the water, as when trailering. A centreboard which consists of solely a pivoting metal plate is called a centerplate. A daggerboard is similar but slides vertically rather than pivoting. The analog in a scow is a bilgeboard: these are fitted in pairs and used one at a time. General History Lt. John Schank (c. 1740 – 6 February 1823) was an officer of the British Royal Navy and is credited with the invention of the centerboard. Schank, however, gave credit for the idea to British Brigadier General ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sculling
Sculling is the use of oars to propel a boat by moving them through the water on both sides of the craft, or moving one oar over the stern. A long, narrow boat with sliding seats, rigged with two oars per rower may be referred to as a scull, its oars may be referred to as sculls and a person rowing it referred to as sculler. Sculling is distinguished from sweep rowing, whereby each boat crew member employs an oar, complemented by another crew member on the opposite side with an oar, usually with each pulling it with two hands and from stern sculling, which uses an oar to propel a vessel with side-to-side movements from the stern. Overview Sculling is a form of rowing in which a boat is propelled by one or more rowers, each of whom operates two oars, one held in the fingers and upper palm of each hand. This contrasts with the other common method of rowing, sweep rowing, in which each rower may use both hands to operate a single oar on either the port or starboard side of the ...

Transom (nautical)
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.
