ABSTRACT:
A boat hull having an underside, a transom and a recess adjacent the transom extending at least partially a transverse dimension or width of the underside. There is also provided a transverse step defining a transverse boundary of the recess as well an internal hollow venting body or reservoir having at least a pair of access ports of restricted cross-sectional size compared with an enlarged cross-sectional area of the venting body. The venting body is in fluid communication with the recess and the hull exterior wherein during travel of the boat hull venting of a low pressure area adjacent the recess can take place without water gaining access to the hull interior in the event of hard turning or rerversing, the water being trapped in the hollow venting body or reservoir. Preferably, the venting body is elongate having a major dimension corresponding to the enlarged cross-sectional area which defines a longitudinal extent of the venting body and a minor dimension defining a transverse extent of the venting body.
