Hiking (sailing)
In sailing, hiking (stacking or stacking out in New Zealand; leaning out or sitting out in United Kingdom) is the action of moving the crew's body weight as far to windward (upwind) as possible, in order to decrease the extent the boat heels (leans away from the wind). By moving the crew's weight to windward, the moment of that force around the boat's center of buoyancy is increased. This opposes the heeling movement of the wind pushing sideways against the boat's sails. It is usually done by leaning over the edge of the boat as it heels. Some boats are fitted with equipment such as hiking straps (or toe straps) and trapezes to make hiking more effective. Hiking is most integral to catamaran and dinghy sailing, where the lightweight boat can be easily capsized or turtled by the wind unless the sailor counteracts the wind's pressure by hiking, or eases the sails to reduce it. The heavy keel on larger keelboats means that it is rare to capsize them due to wind alone, but keel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roberto Briffa
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of ''Hrōþ, Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use Robert (surname), as a surname. Another commonly used form of the name is Rupert (name), Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta (given name), Roberta. The Italian, Portuguese, and Spanish form is Roberto (given name), Roberto. Robert is also a common name in many Germanic languages, including English ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
420 (dinghy)
The International 420 Dinghy is a sailing dinghy popular for racing and teaching. The hull is fiberglass with internal buoyancy tanks. The 420 has a bermuda rig and an optional spinnaker and trapeze. It has a large sail-area-to-weight ratio, and is designed to plane easily. It can be rigged to be sailed single-handed or double-handed. The 420 is an International class recognized by World Sailing. The name refers to the boat's length of . History The International 420 was designed by Christian Maury. The class developed rapidly in France, being adopted nationally as a youth trainer for the larger Olympic class International 470. By the late 1960s the class was adopted by a few UK university sailing clubs for training and team racing. The 420 was designed specifically to be easier to handle than its larger higher-performance cousin, the 470. Construction The class adopted a policy of "prudent evolution" so as to allow development without making existing dinghies obsolete. The ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

Moore 30
The Moore 30 is an American sailboat, that was designed by Gary Mull as a racer and first built in 1985. Production The boat was built by Moore Sailboats in Watsonville, California, United States, starting in 1985. Only five were built and it is now out of production. Design The Moore 30 is a small recreational keelboat, built predominantly of fiberglass. It has a fractional sloop rig and a fixed fin keel. It displaces and carries of ballast. The beam is , including the boat's hiking wings. The boat has a hull speed Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel.

Skate (dinghy)
The Skate is a high performance two-person racing dinghy unique to Australia. Designed as a monohull sailboat it's fourteen feet long (4.27m) with a 7.2m mast, 1.8m bow pole and masthead asymmetrical spinnaker. It is an Australian national class. Because of its small size and lightness it keeps the sailor close to the elements and at the edge of control when navigating water and wind. It makes for wild rides and a relative exhilarating experience of speed at 15 to 25 knots. Most Skates have a 10-foot-long hiking plank for the crew and an 8-foot plank for the skipper. Planks are slid across the hull from one side to the other when tacking and gybing. Other hiking configurations include short wings with two trapezes, longer wings with one trapeze, or trampolines. Many Skates now feature winged rudders to provide increased speed and stability in choppy conditions. One of the top ranked websites quote: "Those who have sailed a Skate will testify that, they provide the most excit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canoe Sailing
Canoe sailing refers to the practice of fitting an Austronesian outrigger or Western canoe with sails. Austronesian sailing canoes The outrigger canoe was one of the key technological innovations of the Austronesian peoples. Although there is little archeological evidence due to perishable building materials, comparative reconstructions indicate that Austronesians already had the distinctive outrigger and crab claw sail technology from at least 2000 BCE. These boats (as well as derivative technologies like the catamaran) enabled them to colonize the islands of Southeast Asia and then later on to Madagascar, the Pacific Islands, and New Zealand. Outrigger canoes like the ''va'a'', ''paraw'', ''jukung'', ''vinta'', and ''proa'' are still used today by traditional fishermen and traders in most of Southeast Asia and Madagascar, and in parts of Oceania. They are constructed from traditional materials, though most incorporate motor engines instead of a sail. In other regions like ...

Tack (sailing)
A tack is a nautical term both for the lower, windward corner of a sail and, ''separately'', for the windward side of a sailing craft (side from which the wind is coming while under way—the starboard or port tack. Generally, a boat is on a starboard tack if the wind is coming over the starboard (right) side of boat with sails on port (left) side. Similarly, a boat is on a port tack if the wind is coming over the port (left) side of boat. However, confusion can result when a boat is on a 'run', with the wind coming directly from astern and the mainsail and jib/genoa are on opposite sides of the vessel (wing-on-wing). Therefore, the windward side is defined as the side opposite to that on which the mainsail is being carried. On a starboard tack the mainsail is carried on the port side. On a port tack the mainsail is carried on the starboard side. It is the position of the mainsail that determines the tack. Sail corner The tack is the corner on a fore-and-aft sail where the ''luf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
49er (dinghy)
The 49er and 49er FX is a two-handed skiff-type high-performance sailing dinghy. The two crew work on different roles with the helm making many tactical decisions, as well as steering, and the crew doing most of the sail control. Both of the crew are equipped with their own trapeze and sailing is done while cantilevered over the water to the fullest extent to balance against the sails. The 49er was designed by Julian Bethwaite (the son of Frank Bethwaite) and developed by a consortium consisting of Bethwaites, Performance Sailcraft Japan, Peter Johnston, and Ovington boats. The boat has been an Olympic class since it was selected by the International Sailing Federation to be the men's high performance double handed dinghy Sydney Summer Games of 2000. Its derivative featuring a re-designed rig, the 49er FX, was selected by World Sailing to be the women's high performance double-hander at the Rio Summer Olympics of 2016. History The 49er's name comes from its hull length of . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skiff
A skiff is any of a variety of essentially unrelated styles of small boats. Traditionally, these are coastal craft or river craft used for leisure, as a utility craft, and for fishing, and have a one-person or small crew. Sailing skiffs have developed into high performance competitive classes. Many of today's skiff classes are based in Australia and New Zealand in the form of , , and skiffs. The 29er, 49er, SKUD and Musto Skiff are all considered to have developed from the skiff concept, all of which are sailed internationally. The term skiff is also used for a racing shell called single scull for competitive rowing. Etymology The word is related to ''ship'' and has a complicated etymology: "skiff" comes from the Middle English ''skif'', which derives from the Old French ''esquif'', which in turn derives from the Old Italian ''schifo'', which is itself of Germanic origin (German ''Schiff''). "Ship" comes from the Old English "scip", which has the same Germanic predecessor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
