This provides the maximum cargo or working space for a given length and beam. The hull shape is also very stable compared to a conventional v-shaped bottom, and in either light chop conditions or above 40 knots (45 mph; 75 km/h) or so in certain conditions can be faster than a flat bottom, for the same weight, length and beam.
The flat bottom simplifies angle measurements on propellers, and makes for easy construction of wings. For many applications the Clark Y has been an adequate airfoil section; it gives reasonable overall performance in respect of its lift-to-drag ratio , and has gentle and relatively benign stall characteristics.
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 ...
The V-hull on the Marine Personnel Carrier (highlighted in green) protects well against IEDs, but raises the center of mass, increasing the likelihood of rollovers. The V-hull is a type of vehicle armor design used on wheeled armored personnel carriers (APCs), infantry mobility vehicles , infantry fighting vehicles (IFVs) and MRAPs .
The Spitfire wing may be classified as: "a conventional low-wing cantilever monoplane with unswept elliptical wings of moderate aspect ratio and slight dihedral".. The wing configuration or planform of a fixed-wing aircraft (including both gliders and powered aeroplanes) is its arrangement of lifting and related surfaces.
The deadrise (which, simplified, is a measure of the angle of bottom in v-hull boats) of most flats boats is generally a small angle because larger deadrise often requires more water displacement which increase the boat's draft and is not desirable for flats boats in shallow water. However, lower deadrise may produce a rougher ride in choppy ...
The Bottom Line. Both progressive and flat tax systems have pros and cons. Economically, a progressive tax reduces the burden on those who can least afford it. However, this does transfer some of ...
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 .
