The ship is assumed to be momentarily still, balanced on the wave with zero velocity and acceleration and the response of the sea is assumed to be that appropriate to static water. In this condition, the curves of weight and buoyancy are deduced. WebHogging describes a beam that curves upwards in the middle, and sagging describes a beam that curves downwards. In solid mechanics, structural engineering, and shipbuilding, hogging and sagging describe the shape that a beam or similar long object will deform into when loading is applied.
