Ballast is weight placed low in ships to lower their centre of gravity, which increases stability (more technically, to provide a righting moment to resist any heeling moment on the hull). Insufficiently ballasted boats tend to tip or heel excessively in high winds. Too much heel may result in the vessel filling with water and/or capsizing. If ...
Weight belts are the most common weighting system currently in use for recreational diving. [17] Weight belts are often made of tough nylon webbing, but other materials such as rubber can be used. Weight belts for scuba and breathhold diving are generally fitted with a quick release buckle to allow the dumping of weight rapidly in an emergency. [7]
Tungsten (also called wolfram) [14] [15] is a chemical element; ... Applications requiring its high density include weights, counterweights, ballast keels for yachts, ...
Cross section of a vessel with a single ballast tank at the bottom. A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural ...
Heavy metals are used for ballast in boats, [137] aeroplanes, [138] and motor vehicles; [139] or in balance weights on wheels and crankshafts, [140] gyroscopes, and propellers, [141] and centrifugal clutches, [142] in situations requiring maximum weight in minimum space (for example in watch movements).
Loaded displacement is the weight of the ship including cargo, passengers, fuel, water, stores, dunnage and such other items necessary for use on a voyage. These bring the ship down to its "load draft". [8] Full load displacement and loaded displacement have almost identical definitions.

Most wakeboard boats will have several features that help to create large wakes. These include ballast, [1] hydrofoil, and hull technology. Ballast is a simple term for weight. When wakeboard boats have ballast tanks, it means that they have room for extra weight to weigh the boat down for larger wakes. For example.
