Sprit Topmast Kalmar Nyckel MD1
The spritsail is a four-sided, Fore-And-Aft Sail, fore-and-aft sail that is supported at its highest points by the mast (sailing), mast and a diagonally running Spar (sailing), spar known as the sprit. The foot of the sail can be stretched by a boom or held loose-footed just by its sheets. A spritsail has four corners: the Parts of a sail#Throat, throat, Parts of a sail#Peak, peak, Parts of a sail#Clew, clew, and Parts of a sail#Tack, tack. The Spritsail can also be used to describe a Rigging, rig that uses a spritsail. Historically, spritsails were the first European fore-and-aft rigs, appearing in Greco-Roman navigation in the 2nd century BC. The rig The luff of the sail is bound to the mast, but unlike the gaff rig where the Parts of a sail#Head (corner), head is bound to a spar, this rig supports the Parts of a sail#Leech, leech of the sail by means of a diagonal spar or spars named a sprit ( ). The forward end of the Sprit, sprit spar is attached to the mast (sailing), m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Points Of Sailing
A point of sail is a sailing craft's direction of travel under sail in relation to the true wind direction over the surface. The principal points of sail roughly correspond to 45° segments of a circle, starting with 0° directly into the wind. For many sailing craft 45° on either side of the wind is a ''no-go'' zone, where a sail is unable to mobilize power from the wind. Sailing on a course as close to the wind as possible—approximately 45°—is termed ''beating'', a point of sail when the sails are ''close-hauled''. At 90° off the wind, a craft is on a ''beam reach''. The point of sail between beating and a beam reach is called a ''close reach''. At 135° off the wind, a craft is on a ''broad reach''. At 180° off the wind (sailing in the same direction as the wind), a craft is ''running downwind''. A given point of sail (beating, close reach, beam reach, broad reach, and running downwind) is defined in reference to the true wind—the wind felt by a stationary observe ...

Rochester Bridge
Rochester Bridge in Rochester, Medway was for centuries the lowest fixed crossing of the River Medway in South East England. There have been several generations of bridge at this spot, and the current "bridge" is in fact four separate bridges: the "Old" bridge and "New" bridge carrying the A2 road, "Railway" bridge carrying the railway and the "Service" bridge carrying service pipes and cables. The bridge links the towns of Strood and Rochester in Medway. All except the railway bridge are owned and maintained by the Rochester Bridge Trust. History Roman The Romans built a bridge across the River Medway as part of Watling Street, carrying traffic from London to Dover (the port for Continental Europe). This was almost certainly the first bridge at the site as the Romans were the first occupiers to have the necessary technology to bridge such a wide and fierce tidal river. The Roman engineers might have initially built a pontoon bridge to support and supply their invading armie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aylesford
Aylesford is a village and civil parish on the River Medway in Kent, England, northwest of Maidstone. Originally a small riverside settlement, the old village comprises around 60 houses, many of which were formerly shops. Two pubs, a village shop and other amenities including a hairdresser, estate agent, two restaurants, a chiropodist and a coffee shop are located on the high street. Aylesford's current population is around 5,000. The Parish of Aylesford covers more than , stretching north to Rochester Airport estate and south to Barming, and has a total population of over 10,000 (as of 2011), with the main settlements at Aylesford, Eccles, Blue Bell Hill and (part of) Walderslade. Aylesford Newsprint was a long-established major employer in the area and was the largest paper recycling factory in Europe, manufacturing newsprint for the newspaper industry. In 2015, Aylesford Paper Mill, as it was known by local residents, was closed down and stripped of all its assets. Hi ... [...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 is often larger than the mainsail. In downwind conditions (with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sail Twist
Sail twist is a phenomenon in sailing where the head of the sail is at a different angle of incidence from the foot of the sail in order to change the lift distribution with height. Twist is measured by comparing the angle of a straight line between the leading edge (luff) and trailing edge (leech) with that of the boom. Some twist is desirable, but too much can induce weather helm or ruin the slot between the mainsail and jib. Three sail shape controls which control the leech tension, and therefore sail twist, are the mainsheet, the boom vang and the traveler. The mainsheet pulls the boom (and therefore the foot of the sail) primarily inwards at lower points of sail and downwards at higher points of sail. Manipulation of the traveler can counteract this because it always pulls the boom laterally. The vang on the other hand does the opposite, it always changes the height of the boom. Computer cut sails can produce the amount of twist specified by the sailmaker, and in different c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cromster
The Crommesteven or cromsteven, often as crompster, cromster or crumster (from ''crom'' = bent, concave; ''steven'' = stem) was a type of small warship used by the Dutch Republic and later by the British fleets during the sixteenth and seventeenth centuries. It was designed for work inshore on the shoal Netherlands coast and was a ketch, spritsail rigged on the main, and lateen on the small mizzen. As a class of vessel, it was represented in England by the hoy. When queen Elizabeth I died in 1603, her navy was reported to consist of 31 great ships, including galleons and crompsters, though crommestevens were considerably smaller than galleons.Corbett, Julian Stafford: ''The successors of Drake'', London : Longmans, Green 1900. p.411 For its size, it was heavily armed and capable of influencing events ashore, in which respect it played a part in the Spanish Armada The Spanish Armada (a.k.a. the Enterprise of England, es, Grande y Felicísima Armada, links=no, lit=Great and Mos ...

Bawley
A bawley was an English sailing vessel typified by a boomless cutter rig and probably named for having a boiler for cooking shrimp in amidships. "The majority were built by Aldous of Brightlingsea",Leather, John, The Gaff Rig Handbook, 2002, Adlard Coles Nautical, London, pages 62-65 but they were also built in Harwich, Erith, Southend, Leigh, and on the Medway.
