134. Which term is given to the upward slope of a vessels bottom from the keel to the bilge?

Rise of floor is the correct term, defining the upward slope of a vessel's bottom from the keel to the bilge. This transverse inclination, also known as deadrise, measures the height increase of the bottom plating as it extends outward from the keel toward the bilge, unlike rake, sheer, and camber which describe longitudinal or deck curvatures.
