Thwart
A thwart is a part of an undecked boat that provides seats for the crew and structural rigidity for the hull. A thwart goes from one side of the hull to the other. There may be just one thwart in a small boat, or many in a larger boat, especially if several oarsmen need to be accommodated. General description A thwart is a part of a boat that usually has two functions: as a seat, and as a structural member that provides some rigidity to the hull. A thwart goes from one side of the hull to the other in an open (undecked) boat, and therefore resists forces pushing in or pulling out the sides of the hull. More obviously it provides a seat for an occupant of a boat. In many sailing boats, a thwart may help support the mast. This can be done either by inserting the mast through a hole in the thwart (with the end resting in a mast step on the keel), or the mast may be clamped to one side of a thwartthis makes it easier to step and unstep the mast whilst afloat.

Canoe Drawing Showing Thwarts - 01
A canoe is a lightweight, narrow water vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel and using paddles. In British English, the term ''canoe'' can also refer to a kayak, whereas canoes are then called Canadian (canoe), Canadian or open canoes to distinguish them from kayaks. However, for official competition purposes, the American distinction between a kayak and a canoe is almost always adopted. At the Olympics, both conventions are used: under the umbrella terms Canoe Slalom and Canoe Sprint, there are separate events for canoes and kayaks. Culture Canoes were developed in cultures all over the world, including some designed for use with sails or outriggers. Until the mid-19th century, the canoe was an important means of transport for exploration and trade, and in some places is still used as such, sometimes with the addition of an outboard motor. Where the canoe played a key r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whaleboat
A whaleboat is a type of open boat that was used for catching whales, or a boat of similar design that retained the name when used for a different purpose. Some whaleboats were used from whaling ships. Other whaleboats would operate from the shore. Later whaleboats usually could operate under sail or oar - American whaling crews in particular obtained better results by making their first approach to a whale under sail, then quickly unstepping the mast and using oars thereafter. Most whaleboats have double-ended, clinker-built hulls of light construction. The hulls were narrow and with sharp ends to achieve the best possible speed for the length of waterline. Length was between 27 and 31 feet. Beam was just over a fifth of the length. Typically they were propelled by five oars when rowed, and stepped a single removable mast when under sail. A rudder was used when under sail and a steering oar when the boat was rowed. The latter provided the manoeuvrability needed when closing ...

Inflatable Boat
An inflatable boat is a lightweight boat constructed with its sides and Bow (watercraft), bow made of Inflatable, flexible tubes containing pressurised gas. For smaller boats, the floor and Hull (watercraft), hull are often flexible, while for boats longer than , the floor typically consists of three to five rigid plywood or aluminium sheets fixed between the tubes, but not joined rigidly together. Often the Transom (nautical), transom is rigid, providing a location and structure for mounting an outboard motor. Some inflatable boats can be disassembled and packed into a small volume, so that they can be easily stored and transported. The boat, when inflated, is kept rigid cross-ways by a foldable removable thwart. This feature makes these boats suitable for Lifeboat (shipboard), liferafts for larger boats or aircraft, and for travel or recreational purposes.

Guildhall Museum Dinghy 3764
A guildhall, also known as a guild hall or guild house, is a historical building originally used for tax collecting by municipalities or merchants in Europe, with many surviving today in Great Britain and the Low Countries. These buildings commonly become town halls and in some cases museums while retaining their original names. As town hall in the United Kingdom In the United Kingdom, a guildhall is usually a town hall: in the vast majority of cases, the guildhalls have never served as the meeting place of any specific guild. A suggested etymology is from the Anglo Saxon "''gild'', or "payment"; the guildhall being where citizens came to pay their rates. The London Guildhall was established around 1120. For the Scottish municipal equivalent see tolbooth.

Strut
A strut is a structural component commonly found in engineering, aeronautics, architecture and anatomy. Struts generally work by resisting longitudinal compression, but they may also serve in tension. A stay is sometimes used as a synonym for strut, but some sources distinguish that struts are braces for holding compressive forces apart, while stays are braces for keeping stretching forces together. Human anatomy Part of the functionality of the clavicle is to serve as a strut between the scapula and sternum, resisting forces that would otherwise bring the upper limb close to the thorax. Keeping the upper limb away from the thorax is vital for its range of motion. Complete lack of clavicles may be seen in cleidocranial dysostosis, and the abnormal proximity of the shoulders to the median plane in cases of this genetic condition exemplifies the clavicle's importance as a strut. Architecture and construction Strut is a common name in timber framing for a support or brace of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
