The boats' shallow draft worked well in rivers while its flat bottom profile allowed heavy loading of cargoes and provided stability. The smallest batteau required only one crewman, while larger ones, reaching up to 58 feet (17.68 meters) in length, required up to five. The largest batteaux could carry two to ten tons of cargo.
The reason a flat bottom canoe has lower final stability is that the hull must wrap a sharper angle between the bottom and the sides, compared to a more round-bottomed boat. [44] Keel: an external keel makes a canoe track (hold its course) better and can stiffen a floppy bottom, but it can get stuck on rocks and decrease stability in rapids. [48]
A pirogue has "hard chines" which means that instead of a smooth curve from the gunwales to the keel, there is often a flat bottom which meets the plane of the side. In his 1952 classic song " Jambalaya ", Hank Williams refers to the pirogue in the line "me gotta go pole the pirogue down the bayou".
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 .
Topside: the top portion of the outer surface of a ship on each side above the waterline. [1] Underdeck: a lower deck of a ship. [21] Yardarm: an end of a yard spar below a sail. Waterline: where the water surface meets the ship's hull. Weather: side or direction from which wind blows (same as "windward"). [16]
Chine log construction works best for hulls where the sides join a flat bottom at a right angle, but it can be used for other angles as well with an appropriately angled chine log. Builders of small boats such as punts, where the plank thickness is large compared to the size of the hull, can dispense with the chine log and nail intersecting ...
A keel boat, [1] keelboat, [1] or keel-boat [2] is a type of usually long, narrow cigar-shaped riverboat, [1] 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 ...
Phil Bolger designed a rudimentary solution to the problem of hull slap at anchor, which effects flat bottom boats, by making a 3 foot long, oval shaped anti-slap pad of multiple layers of ply about 2 inches deep, which were then rounded into a shallow arc. The noise is the same as chine slap familiar to owners of deep-V powerboats at anchor.
