Abstract
The invention pertains to a propeller pocket for reducing the draft of propeller driven marine craft, and the propeller pocket of the invention utilizes an increasing vertical dimension in the direction of the craft stern, the pocket being defined by planar surfaces, and the water within the pocket being 'gathered' as the water approaches the stern to minimize cavitation at the propeller. The pocket is advantageous for use with either inboard, inboard/outboard or outboard driven installations and provides increased drive efficiencies with a reduction in hull draft.
