The approach the floor timbers of a vessel makes to a vertical. In the case of ships, the frames in the after body are called the dead-risings, because they only rise from the keel at a sharp angle, all the middle frames starting out nearly horizontally from the keel. A yacht is said to have considerable dead rise on a very rising floor, when she is more or less of the V form, but really vessels of the T form have the greatest dead rise, as the heels of the floors forming the framing to take the garboards do rise nearly vertically.
