Abstract
A vessel hull for an inboard-powered marine vessel includes a hull body having a hull bottom that includes a contoured pod mounting surface positioned longitudinally between a central keel and a stern of the hull body. The contoured pod mounting surface has a planar mounting face, for mounting a propulsor pod, and a transition face each positioned between peripheral edges of the pod mounting surface. The transition face slopes forwardly and downwardly from the planar mounting face to the central keel and follows a contour defining a sine wave pattern.

A marine vessel comprising:
- a vessel hull including a hull body having a bow, a stern, an upper hull body side, and a lower hull body side having a hull bottom;
- the hull bottom including a first hull bottom side surface and a second hull bottom side surface, the first hull bottom side surface and the second hull bottom side surface adjoining one another in a V-pattern so as to form a central keel;
- the hull bottom further including a contoured pod mounting surface positioned longitudinally between the central keel and the stern and having a first peripheral edge and a second peripheral edge oriented so as to diverge from one another rearwardly from the central keel;
- the contoured pod mounting surface further including a planar mounting face extending forwardly from the stern, and a transition face sloping forwardly and downwardly from the planar mounting face to the central keel, such that the contoured pod mounting surface forms, within the transition face, has' a concave longitudinal profile that extends from the planar mounting face to the central keel;
- and
- a propulsor pod mounted upon the planar mounting face.
