What I claim is:
1. A water craft having at least one rotatable float body of a general cylindrical form and defined by a helical winding extending from the front end to the rear end of said body, with the helicoidal development of the winding beginning at said front end and terminating at said rear end at or substantially at the full diameter of the body in a plane substantially perpendicular to the general longitudinal axis of the body, the adjacent portions of the winding defining a passage the depth of which diminishes progressively over its entire length from said front end to said rear end.
