ABSTRACT:
An inboard power boat for towing water skiers is disclosed which incorporates a wake control device. The boat has a hull configuration in which the stern portion has a flat or semi-flat bottom. The wake control device is comprised of a single flat plate which is pivotally mounted to the stern along the longitudinal axis of the hull. An hydraulic control circuit is provided for pivoting the plate about a transverse axis so that its trailing end moves between raised and lowered positions. The trailing end is moved to a selected position to selectively control the size of the wake as the trailing edge projects to a lesser or greater extent into the stream of water which moves under the hull as the boat moves forward.
