Human-powered Watercraft
Human-powered watercraft are watercraft propelled by human power. The three main methods of collecting human power are directly from the hands or feet, through the hands with oars, paddles, or poles, or through the feet with pedals and a crank or treadle. While most human-powered watercraft use buoyancy to maintain their position relative to the surface of the water, a few, such as human-powered hydrofoils and human-powered submarines, use hydrofoils, either alone or in addition to buoyancy. Oared craft Oars are held at one end, have a blade on the other end, and pivot in between in oarlocks. Oared craft include: * Racing shell Using oars in pairs, with one hand on each oar, is two-oar sculling. The oars may also be called sculls. Two-oared sculled craft include: * Adirondack guideboat * Banks dory, Gloucester dory, and McKenzie River dory * Dinghy * Sampans rowed by foot in Ninh Bình Province of northern Vietnam. * Scull, Single scull, Double scull, Quad scull, ...

Sweep (rowing)
Sweep rowing is one of two disciplines of the sport of rowing. In sweep rowing each rower has one oar, usually held with both hands. As each rower has only one oar, the rowers have to be paired so that there is an oar on each side of the boat. In the United Kingdom, rowing generally refers to sweep rowing only. The term pulling was also used historically.W B Woodgate ''Boating'' Read Books, 2008 In the other rowing discipline, sculling, each rower holds two oars, one in each hand. Sweep or single oar rowing has a long history and was the means of propulsion for Greek triremes and Viking longboats. These boats were wide enough for the pairs of rowers to sit alongside each other. Boats can go faster, the narrower they are, because a smaller cross-sectional area reduces drag and wave drag and gives a sharper angle to the bow. The hulls can be kept narrower by attaching riggers to the gunwales, so that the oarlocks can be placed farther out to carry longer oars. A narrower hull me ...

Racing Shell
In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ''shell'') is an extremely narrow, and often comparatively long, rowing boat specifically designed for racing or exercise. It is outfitted with long oars, outriggers to hold the oarlocks away from the boat, and sliding seats. The boat's long length and semicircular cross-section reduce drag to a minimum. This makes the boat both fast and unstable. It must be balanced by the rowers to avoid tipping. Being able to balance – or "set" – the boat while putting maximum effort into the oars is therefore an essential skill of sport rowing. History The racing shell evolved from the simple working rowboat. Boats with longer hulls and narrower in beam were developed in the early 19th century specifically for team racing. These dedicated boats were the first boats that could be called racing shells, and they evolved into the highly specialized forms used today. Riggers A narrower boat provides a sharp ...

Quad Scull
A quadruple sculling boat, often simply called a quad and abbreviated 4x, is a rowing boat used in the sport of competitive rowing. It is designed for four people who propel the boat by sculling with two oars, or "sculls", one in each hand. Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to reduce drag. They usually have a fin towards the rear, to help prevent roll and yaw. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fiber reinforced plastic) for strength and weight advantages. The riggers in sculling apply the forces symmetrically to each side of the boat. Quad sculls is one of the classes recognized by the International Rowing Federation and the Olympics. FISA rules specify minimum weights for each class of boat so that no individual will gain a great advantage from the use of expensive materials or technology. When there are four rowers in a boat, each w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Scull
A double scull is a rowing boat used in the sport of competitive rowing. It is designed for two persons who propel the boat by sculling with two oars each, one in each hand. Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to reduce drag to a minimum. They usually have a fin towards the rear, to help prevent roll and yaw. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and weight advantages. The riggers in sculling apply the forces symmetrically to each side of the boat. Double sculls is one of the classes recognized by the International Rowing Federation and the Olympics. In contrast to the combination of the coxed pair, in which the distribution of the riggers means the forces are staggered alternately along the boat, the symmetrical forces in sculling make the boat more efficient and so the double scull is faster than t ...

Single Scull
A single scull (or a scull) is a rowing boat designed for a single person who propels the boat with two oars, one in each hand. Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section in order to minimize drag. They have riggers, which apply the forces symmetrically to each side of the boat and (usually) a fin towards the rear which helps prevent roll and yaw. Originally made from wood, shells are now almost always made from a composite material (usually carbon-fibre reinforced plastic) for strength and weight advantages. Recreational single sculls tend to be shorter and a little wider than racing boats and can have a slightly flattened hull shape to provide more stability. Recreational single sculls can be made of a variety of materials including carbon fiber, fiberglass, wood or rotomoulded polyethylene. The single scull is the 2nd slowest category of racing boat (faster than the coxed pair), and competitors are recognised by other ...

Scull
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 th ...

Sampan
A sampan is a relatively flat-bottomed Chinese and Malay wooden boat. Some sampans include a small shelter on board and may be used as a permanent habitation on inland waters. The design closely resembles Western hard chine boats like the scow or punt. Sampans are generally used for transportation in coastal areas or rivers and are often used as traditional fishing boats. It is unusual for a sampan to sail far from land, as they do not have the means to survive rough weather. Some think that "sampan" is the Cantonese pronunciation of the Chinese word 舢舨, or "shan-ban" in "Pinyin" (standard) pronunciation). Of the two characters, "舢" (shan, literally "mountain-like") means ocean-going large ship, and "舨" (ban, literally "return") means small boat for shuttling between the ship and shore. Since the small boat is necessary for the big ship where deep water port was not available, it became one word meaning "the small boat for the big ship". Later it was general ...

Dinghy
A dinghy is a type of small boat, often carried or towed by a larger vessel for use as a tender. Utility dinghies are usually rowboats or have an outboard motor. Some are rigged for sailing but they differ from sailing dinghies, which are designed first and foremost for sailing. A dinghy's main use is for transfers from larger boats, especially when the larger boat cannot dock at a suitably-sized port or marina. The term "dinghy towing" sometimes is used to refer to the practice of towing a car or other smaller vehicle behind a motorhome, by analogy to towing a dinghy behind a yacht. Etymology The term is a loanword from the Bengali ', Urdu ', and Hindi '. Types Dinghies usually range in length from about . Larger auxiliary vessels are generally called tenders, pinnaces or lifeboats. Folding and take-down multi-piece (nesting) dinghies are used where space is limited. Some newer dinghies have much greater buoyancy, giving them more carrying capacity than old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McKenzie River Dory
The McKenzie River dory, or drift boat, is an adaptation of the open-water dory converted for use in rivers. A variant of the boat's hull is called a modified McKenzie dory or Rogue River dory. The McKenzie designs are characterized by a wide, flat bottom, flared sides, a narrow, flat bow, and a pointed stern. The sole identifying characteristic of the McKenzie River dory is a continuous rocker (the arc from bow to stern along the bottom of the boat). It is this constant rocker that allows the boat to spin about its center for ease in maneuvering in rapids. History McKenzie River dories are specialized to run rapids on rivers, and first appeared on the McKenzie River in Oregon in the mid-20th century. A prolific McKenzie River dory boat builder in the 1940s and 1950s was Wood "Woodie" Knoble Hindman. Woodie had learned to build these steep rocker boats from master boat builder Torkel "Tom" Kaarhus. The McKenzie River dory Woodie made had a pronounced continuous rocker with a ...

Gloucester Dory
The Gloucester dory is a variant of the Banks dory, a type of narrow-bottomed, slab-sided boat, common in the North Eastern United States. It is characteristically smaller and lighter, with less overhang, both bow and stern, and less freeboard. It retains the Banks dory's slab sides. Gloucester dories were designed to be launched through the surf behind a breakwater for daily fishing and lobstering off the Massachusetts shore. Because of its simple lines, a Gloucester dory is relatively easy to build. With the straight sides and flat bottom, stitch and glue techniques work well with this boat. See also * Dory * Swampscott dory The Swampscott dory is a traditional fishing boat, used during the middle of the 19th century by fishing villages along the North Shore coast of Massachusetts centered on Swampscott.

Banks Dory
The Banks dory, or Grand Banks dory, is a type of dory. They were used as traditional fishing boats from the 1850s on the Grand Banks of Newfoundland. The Banks dory is a small, open, narrow, flat-bottomed and slab-sided boat with a particularly narrow transom. They were inexpensive to build and could be stacked or nested inside each other and stored on the decks of larger fishing vessels which functioned as mother ships. Banks dories have long overhangs at the bow and stern which helps them lift over waves. There were one-man and two-man versions. Most could be fitted with sails. The dories became more stable when they were loaded with about half a ton of catch. Production The Banks dory type is very simple and efficient to produce, making them well suited to mass production. By 1880, Bank dories were being built in large numbers in the Massachusetts towns of Gloucester, Beverly, Essex, Newburyport, and Salisbury (Amesbury). Other major areas of production included Seabrook ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
