An inclining test is a test performed on a ship to determine its stability, lightship weight and the coordinates of its center of gravity.The test is applied to newly constructed ships greater than 24m in length, and to ships altered in ways that could affect stability.
In a boat, the equivalent of the spring stiffness is the distance called "GM" or "metacentric height", being the distance between two points: "G" the centre of gravity of the boat and "M", which is a point called the metacentre. Metacentre is determined by the ratio between the inertia resistance of the boat and the volume of the boat. (The ...
The ship's hydrostatic tables show the corresponding volume displaced. [4] To calculate the weight of the displaced water, it is necessary to know its density. Seawater (1,025 kg/m 3) is more dense than fresh water (1,000 kg/m 3); [5] so a ship will ride higher in salt water than in fresh. The density of water also varies with temperature.
Loadline displacement – The weight or mass of the ship loaded to the load line or plimsoll mark. Deadweight tonnage (DWT) is a measure of how much weight a ship can carry. [ 1 ] [ 2 ] [ 3 ] It is the sum of the weights of cargo, fuel, fresh water, ballast water , provisions, passengers, and crew.
Dimensional weight, also known as volumetric weight, is a pricing technique for commercial freight transport (including courier and postal services), which uses an estimated weight that is calculated from the length, width and height of a package. The shipping fee is based upon the dimensional weight or the actual weight, whichever is greater.
AAW An acronym for anti-aircraft warfare. aback (of a sail) Filled by the wind on the opposite side to the one normally used to move the vessel forward.On a square-rigged ship, any of the square sails can be braced round to be aback, the purpose of which may be to reduce speed (such as when a ship-of-the-line is keeping station with others), to heave to, or to assist moving the ship's head ...
Based on data analysis done on a survey of over 3,000 Americans, weight and height discrimination, a form of sizeism, was ranked just behind gender, age, and race as a highly experienced factor of discrimination. Among female respondents, weight and height discrimination exceeds race-based discrimination as the third most prevalent form of ...
Crew lining the gunwale of J Class yacht Ranger Video of a J Class race. A table of well-known J Class yachts demonstrating that application of the Universal Rule could result in a rating from 65 to 76 feet (20 to 23 m). Length overall (LOA) of the yachts ranged from 119 to 139 feet (36 to 42 m).
