A ski boat for producing a relatively small, well-defined wake and a relatively smooth working table includes a V-shaped keel section. The angle of the 'V' increases towards the stern of the hull. A chine panel is mounted at each of the outboard edges of the keel section. A secondary chine is located on each side of the keel section, being parallel to the centerline of the V-shaped keel section and following the contour of the keel section. A concave depression panel is located at the stern of the boat, extending forwardly therefrom into the keel section.
