Coypu (dinghy)
The Coypu is a class of small sailing dinghy. It is a highly stable boat, suitable for beginners, and is normally sailed by two people, although three can be accommodated comfortably. Design The variants in the design of the coypu depend on the builder. The hull is normally glass-reinforced plastic construction, with buoyancy tanks on front, sides, and rear. The centreboard is metal, and the rudder is removable, either fixed (i.e. does not have a downhaul) or with a moveable blade. Most Coypu mainsails are normally raised by feeding the luff into the track on the mast, although some variants have gunter rig sails. The mainsheet is fixed to the stern of the boat. A jib is used for normal use and only one size is available. The boat is heavy in comparison with other dinghies, so traditionally they have proved popular at training centres where removing the boat from the water on a regular basis is not necessary. However, the design provides a stable boat in all weather, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monohull
right A monohull is a type of boat having only one hull, unlike multihulled boats which can have two or more individual hulls connected to one another. Fundamental concept Among the earliest hulls were simple logs, but these were generally unstable and tended to roll over easily. Hollowing out the logs into a dugout canoe doesn't help much unless the hollow section penetrates below the log's center of buoyancy, then a load carried low in the cavity actually stabilizes the craft. Adding weight or ballast to the bottom of the hull or as low as possible within the hull adds stability. Naval architects place the center of gravity substantially below the center of buoyancy; in most cases this can only be achieved by adding weight or ballast. The use of stones and other weights as ballast can be traced back to the Romans, Phoenicians and Vikings. Modern ships carry tons of ballast in order to maintain their stability; even heavily laden cargo ships use ballast to optimize the distr ...

Mainsheet
In sailing, a sheet is a line (rope, cable or chain) used to control the movable corner(s) (clews) of a sail. Terminology In nautical usage the term "sheet" is applied to a line or chain attached to the lower corners of a sail for the purpose of extension or change of direction. The connection in derivation with the root "shoot" is more clearly seen in "sheet-anchor", one that is kept in reserve, to be "shot" in case of emergency. Fore-and-aft rigs Fore-and-aft rigs comprise the vast majority of sailing vessels in use today, including effectively all dinghies and yachts. The sheet on a fore-and-aft sail controls the angle of the sail to the wind, and should be adjusted to keep the sail just filled. Most smaller boats use the Bermuda rig, which has two or three sets of sheets: * The mainsheet is attached to the boom, and is used to control the mainsail. In a rig with no boom on the mainsail, the mainsheet would attach directly to the mainsail clew. A mainsheet is a line con ...

Norfolk
Norfolk () is a ceremonial and non-metropolitan county in East Anglia in England. It borders Lincolnshire to the north-west, Cambridgeshire to the west and south-west, and Suffolk to the south. Its northern and eastern boundaries are the North Sea, with The Wash to the north-west. The county town is the city of Norwich. With an area of and a population of 859,400, Norfolk is a largely rural county with a population density of 401 per square mile (155 per km2). Of the county's population, 40% live in four major built up areas: Norwich (213,000), Great Yarmouth (63,000), King's Lynn (46,000) and Thetford (25,000). The Broads is a network of rivers and lakes in the east of the county, extending south into Suffolk. The area is protected by the Broads Authority and has similar status to a national park. History The area that was to become Norfolk was settled in pre-Roman times, (there were Palaeolithic settlers as early as 950,000 years ago) with camps along the higher land ...

Hertfordshire
Hertfordshire ( or ; often abbreviated Herts) is one of the home counties in southern England. It borders Bedfordshire and Cambridgeshire to the north, Essex to the east, Greater London to the south, and Buckinghamshire to the west. For government statistical purposes, it forms part of the East of England region. Hertfordshire covers . It derives its name – via the name of the county town of Hertford – from a Hart (deer), hart (stag) and a Ford (crossing), ford, as represented on the county's coat of arms and on the Flag of Hertfordshire, flag. Hertfordshire County Council is based in Hertford, once the main market town and the current county town. The largest settlement is Watford. Since 1903 Letchworth has served as the prototype Garden city movement, garden city; Stevenage became the first town to expand under post-war Britain's New Towns Act 1946, New Towns Act of 1946. In 2013 Hertfordshire had a population of about 1,140,700, with Hemel Hempstead, Stevenage, Watford ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rickmansworth
Rickmansworth () is a town in southwest Hertfordshire, England, about northwest of central London and inside the perimeter of the M25 motorway. The town is mainly to the north of the Grand Union Canal (formerly the Grand Junction Canal) and the River Colne. The town of Watford is to the northeast. Rickmansworth is the administrative seat of the Three Rivers District Council. The confluence of the River Chess and the River Gade with the Colne in Rickmansworth inspired the district's name. The enlarged Colne flows south to form a major tributary of the River Thames. The town is served by the Metropolitan line of the London Underground and Chiltern Railways from London Marylebone to Aylesbury railway station. Toponymy The name Rickmansworth comes from the Saxon name ''Ryckmer'', the local landowner, and ''worth'' meaning a farm or stockade. In the Domesday Book of 1086 it was recorded as the Manor of Prichemaresworde. Other spellings include Rykemarwurthe (1119–46 ...

Sea Scout
Sea Scouts are a part of the Scout movement, with a particular emphasis on boating and other water-based activities on the sea, rivers or lakes (canoeing, rafting, scuba, sailboarding). Sea Scouts can provide a chance to sail, cruise on boats, learn navigation, learn how to work on engines and compete in regattas. Sea Scouts often have distinctive uniforms. In some countries or Scout organizations, Sea Scouting is a program just for older Scouts. History One of the earliest records of "Sea Scouts" is in ''Chums'' magazine which refers to "Sea Scouts" as early as July 1909. These Sea Scouts were part of the Chums Scouts and British Boy Scouts. Also in the ''Chums'' magazine, the British Boys Naval Brigade, later National Naval Cadets, were subtitled 'Scouts of the Sea' from the 14 July 1909 edition and, from the 28 July 1909 edition, 'Sea Scouts of the Empire'. The British Boy Scouts and an original company of The National Naval Cadets were both headquartered in Batter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stern
The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite the bow, the foremost part of a ship. Originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a white navigation light at night. Sterns on European and American wooden sailing ships began with two principal forms: the ''square'' or ''transom'' stern and the ''elliptical'', ''fantail'', or ''merchant'' stern, and were developed in that order. The hull sections of a sailing ship located before the stern were composed of a series of U-shaped rib-like frames set in a sloped or "cant" arrangement, with the last frame before the stern being called the ''fashion timber(s)'' or ''fashion piece(s)'', so called for "fashioning" the after part of the ship. This frame is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Mainsail
A mainsail is a sail rigged on the main mast of a sailing vessel. * On a square rigged vessel, it is the lowest and largest sail on the main mast. * On a fore-and-aft rigged vessel, it is the sail rigged aft of the main mast. The sail's foot is normally attached to a boom. (In extremely heavy weather, the mainsail may be lowered, and a much smaller trysail hoisted in its place). Historical fore-and-aft rigs used a four-sided gaff rigged mainsail, sometimes setting a gaff topsail above it. Whereas once the mainsail was typically the largest sail, today the mainsail may be smaller than the jib or genoa; Prout catamarans typically have a mainmast stepped further aft than in a standard sloop, so that the mainsail is much smaller than the foresail. Bermuda rig The modern Bermuda rig uses a triangular mainsail aft of the mast, closely coordinated with a jib for sailing upwind. A large overlapping jib or genoa Genoa ( ; it, Genova ; lij, Zêna ). is the capital of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downhaul
The downhaul is a line which is part of the rigging on a sailboat; it applies downward force on a spar or sail. The most common downhaul on a modern sailboat is attached to the spinnaker pole, though this may be referred to as the foreguy in some rigging nomenclature. The term is also commonly applied to the cunningham on the mainsail. In a windsurfing rig, the downhaul is the primary load-bearing line which controls the sail's shape. Modern windsurfing sails incorporate a sleeve for the mast, and therefore do not have a halyard In sailing, a halyard or halliard is a line (rope) that is used to hoist a ladder, sail, flag or yard. The term ''halyard'' comes from the phrase "to haul yards". Halyards, like most other parts of the running rigging, were classically made of ... which tensions the top of the sail. The downhaul is tensioned early in the rigging process and is generally not adjustable on the water, and is therefore rather different in use than the downhaul on a sailb ...
