Book excerpt: Excerpt from A Manual of Yacht and Boat Sailing The displacement of a vessel is the quantity or bulk of water (generally represented by a measure of weight) which a vessel displaces or pushes away when she is put into the water. This quantity of water is always equal to the whole weight of the vessel and everything that She contains; that is to say, the vessel will sink into the water until she has displaced a quantity of the uid equal to her own weight and the weight of everything that she contains. If the weight of water displaced is exactly equal in bulk to the bid]: of the vessel, then the latter will sink in the uid until her entire bulk is immersed; or, in other words, if the body immersed be a solid of the specific gravity of the water, then will the solid sink into the uid until it is entirely immersed. For example, a cubic foot of African oak weighs 621b., a cubic foot of fresh water weigh 62 lb., and consequently, if a cubic foot of African oak were placed in fresh water, it would nearly sink to the level of the surface; but a cubic foot of sea water weighs 64lb., and consequently, if a cubic foot of African oak were placed into sea water, it would sink until 621b. Of the uid were displaced (which would be less than a cubic foot), and would sink no deeper, so practically 2lb. Of the oak cube would remain above the surface. This well illustrates the meaning of the term a vessel's displace. Ment. A vessel weighs, we will say, with all her ballast, spars, sails, gear, stores, crew, and everything belonging to her on board, one ton; then, if she is put into the water, she will displace exactly one ton of the uid. Now a ton of sea water in bulk contains 35 cubic feet; consequently, if the bulk of the vessel only equalled 35 cubic feet, she would sink into the water until entim immersed. But a vessel that weighed one ton would contain in bulk a great deal more than 35 cubic feet, measuring her actual body on the outside from deck to keel as if she were a solid.
