ABSTRACT:
Transitional time through the transplaning speed realm of a high speed sport/utility boat is reduced by narrow, concave planing tabs secured along the inside bottom surface of after-sponsons in alignment with the hull lifting strakes. Such planing tabs originate from the lower transom plane with an abrupt, 1 to 3 inch, step above the intersection edge of the hull bottom surface with the lower transom plane. From the lower transom plane, the planing tab length is terminated at or shortly past the boat propeller plane.
