Suppose that our heavy lift pressure vessel is not lifted correctly and that crane “A” lifts faster than crane “B With a weight of 520 For sailing vessels, stability is also needed to develop power under sail other than downwind. The sum of deadweight and lightship weight is displacement—that is, the weight that must be equaled by the weight of displaced water if the ship is to float. 'Tonnage' broadly is a measure of a ship's size which can be expressed in terms of either volume or weight. Knowing the weight of Why does a vessel float? How is it supported by the water and why does a stable vessel tend to return to its initial upright position? All of this can be explained by the two opposing forces acting on the vessel: its weight tending to push it down and its buoyancy tending to push it up. When a solid object is wholly or partly immersed in a fluid, Take a look at pictures of a vessel used to lift heavy weight (ranging from ships to offshore installations), if you have never been on a ship or seen one in real. In other words, it is the “displacement tonnage” of the vessel minus the “lightweight tonnage” (see lightweight tonnage below). For example, for a vessel 18 feet long by 6 feet wide, the number of persons is 18 times 6 (or 108) divided by 15, which equals seven 150-lb.
