Flat-bottomed Boat
A flat-bottomed boat is a boat with a shallow draft, two-chined hull, which allows it to be used in shallow bodies of water, such as rivers, because it is less likely to ground. The flat hull also makes the boat more stable in calm water, which is good for hunters and anglers. However this design becomes less stable in choppy water. This is because it causes the boat to travel ''on'' the water, instead of ''through'' it, as a boat with a rounded or V-shaped hull would. Flat hulls are simple to construct, making them popular with boat-building hobbyists. In Britain they came to popular notice during the planned French invasion of Britain in 1759, when a large-number of flat-bottomed boats were prepared by the French to ferry their invasion force across the channel and a number were destroyed during the British Raid on Le Havre. The flat-bottoms are mentioned in the song ''Heart of Oak'' written by David Garrick during 1759. Types *Barge * Bateau * Bull boat * Car float ...

Pontoon Boat
A pleasure boat with two lengthwise pontoons A pontoon boat is a flattish boat that relies on floats to remain buoyant. These pontoons (also called ''tubes'') contain much reserve buoyancy and allow designers to create large deck plans fitted with a variety of accommodations including expansive lounge areas, stand-up bars, and sun pads. Better tube designs have allowed builders to put ever-increasing amounts of horsepower on the stern. Pontoon boat drafts may be as shallow as eight inches (20 centimetres), which reduces risk of running aground and underwater damage, this allows it to come close to shore to pick up and drop off loads. History A pontoon ferry crossing the Zambezi at Kazungula The 1951 invention of the pontoon motorboat in the United States is credited to a farmer who lived on the Horseshoe chain of lakes, near Richmond, Minnesota. Ambrose Weeres put a wooden platform on two columns of steel barrels welded together end-to-end, creating a sturdy deck that woul ...

Pirogue
A pirogue ( or ), also called a piragua or piraga, is any of various small boats, particularly dugouts and native canoes. The word is French and is derived from Spanish , which comes from the Carib '. Description The term 'pirogue' does not refer to a specific kind of boat, but is a generic term for small native boats in regions once colonized by France and Spain, particularly dugouts made from a single log. In French West Africa, the term refers to handcrafted banana-shaped boats used by traditional fishermen. In Madagascar, it also includes the more elaborate Austronesian ''lakana'' outrigger canoe. Pirogues are usually propelled by paddles that have one blade (as opposed to a kayak paddle, which has two). It can also be punted with a push pole in shallow water. Small sails are built by local fishermen, and they can also be employed. There are two types of sails with differences in their shapes: the square one is used mainly for fishing near the coast and is only usefu ...

Landing Ship, Tank
Landing Ship, Tank (LST), or tank landing ship, is the naval designation for ships first developed during World War II (1939–1945) to support amphibious operations by carrying tanks, vehicles, cargo, and landing troops directly onto shore with no docks or piers. This enabled amphibious assaults on almost any beach. The LST had a highly specialized design that enabled ocean crossings as well as shore groundings. The bow had a large door that could open, deploy a ramp and unload vehicles. The LST had a flat keel that allowed the ship to be beached and stay upright. The twin propellers and rudders had protection from grounding. The LSTs served across the globe during World War II including in the Pacific War and in the European theatre. The first tank-landing ships were built to British requirements by converting existing ships; the UK and the US then collaborated upon a joint design. The British ships were used in late 1942 during the Allied invasion of Algeria, by 1943 L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keelboat
A keelboat is a riverine cargo-capable working boat, or a small- to mid-sized recreational sailing yacht. The boats in the first category have shallow structural keels, and are nearly flat-bottomed and often used leeboards if forced in open water, while modern recreational keelboats have prominent fixed fin keels, and considerable draft. The two terms may draw from cognate words with different final meaning. A keep boat, keelboat, or keel-boat is a type of usually long, narrow cigar-shaped riverboat, or unsheltered water barge which is sometimes also called a poleboat—that is built about a slight keel and is designed as a boat built for the navigation of rivers, shallow lakes, and sometimes canals that were commonly used in America including use in great numbers by settlers making their way west in the century-plus of wide-open western American frontiers. They were also used extensively for transporting cargo to market, and for exploration and trading expeditions, for w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jon Boat
A jon boat (or johnboat) is a flat-bottomed boat constructed of aluminum, fiberglass, wood, or polyethelene with one, two, or three seats, usually bench type. They are suitable for fishing, hunting and cruising. The nearly flat hull of a jon boat tends to ride ''over'' the waves rather than cut ''through'' them as a V-hull might; this shallow draft – only a few inches – enables the jon boat to operate in very shallow water, but limits its use to calm waters. Jon boats typically have a transom onto which an outboard motor can be mounted. They are simple and easy to maintain, and inexpensive, though with many options to upgrade. Typical options may include live wells/bait wells, side or center consoles, factory installed decks and floors, electrical wiring, accessory pads/mountings, and casting and poling platforms. Jon boats are available commercially between long and wide, though custom sizes may be found. The simple design includes an open hull, without a bilge, leaving ...

Gondola
The gondola (, ; vec, góndoła ) is a traditional, flat-bottomed Venetian rowing boat, well suited to the conditions of the Venetian lagoon. It is typically propelled by a gondolier, who uses a rowing oar, which is not fastened to the hull, in a sculling manner and also acts as the rudder. The uniqueness of the gondola includes its being asymmetrical along the length making the single-oar propulsion more efficient. For centuries, the gondola was a major means of transportation and the most common watercraft within Venice. In modern times, the boats still do have a role in public transport in the city, serving as ''traghetti'' (small ferries) over the Grand Canal operated by two oarsmen. Various types of gondola boats are also used in special regattas (rowing races) held amongst gondoliers. Their primary role today, however, is to carry tourists on rides at fixed rates. There are approximately 400 licensed gondoliers in Venice and a similar number of boats, down from the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flatboat
A flatboat (or broadhorn) was a rectangular flat-bottomed boat with square ends used to transport freight and passengers on inland waterways in the United States. The flatboat could be any size, but essentially it was a large, sturdy tub with a hull. A flatboat was almost always a one-way (downstream) vessel, and was usually dismantled for lumber when it reached its destination. Early history The flatboat trade first began in 1781, with Pennsylvania farmer Jacob Yoder building the first flatboat at Old Redstone Fort on the Monongahela River. Yoder's ancestors immigrated from Switzerland, where small barges called weidlings are still common today, having been used for hundreds of years to transport goods downriver. Yoder shipped flour down the Ohio River and Mississippi River to the port of New Orleans. Other flatboats would follow this model, using the current of the river to propel them to New Orleans where their final product could be shipped overseas. Through the an ...

Durham Boat
The Durham boat was a large wooden, flat-bottomed, double-ended freight boat which was in use on many of the interior waterways of North America beginning in the middle of the eighteenth century. They were replaced by larger, more efficient canal boats during the canal era beginning with the opening of the Erie Canal in 1825. The Durham name became associated with this boat type due to their use by the Durham Ironworks of Durham, Pennsylvania for hauling freight on the Delaware River. They are also noted for their use in George Washington's crossing of the Delaware River during the American Revolution. Construction Durham boats were flat-bottomed and double-ended, much like large bateaux in both construction and appearance. Beyond that, very little is known of construction details. No plans exist and likely they were not used. No extant remains have been found and very little written description exists. Probably they were built with heavy stems at bow and stern and a series of fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dory
A dory is a small, shallow-draft boat, about long. It is usually a lightweight boat with high sides, a flat bottom and sharp bows. It is easy to build because of its simple lines. For centuries, the dory has been used as a traditional fishing boat, both in coastal waters and in the open sea. Definition Strictly speaking, the only true defining characteristic of the dory is that it is planked with wide straight boards running fore-and-aft; "It should be well understood, that it is the dory's special mode of construction, not its hull shape, that sets it, and its related sub-types apart from other boats".Gardner, page 15. More generally speaking, the dory can be defined as a small boat which has: * a flat bottom, with the bottom planks fastened lengthwise (bow to stern). * a hull shape defined by the natural curve of a sawn plank (never steam-bent). * planks overlapping the stem at the front of the boat and an outer "false" stem covering the hood ends of the planks. * (with som ...
