A propeller drive for watercraft, preferably for ferry boats and car ferries, which has two propellers located one behind the other in the center-line plane. The forward propeller is preferably located on a marine shaft which exits the hull, and can be driven by means of a drive system. The aft propeller is preferably driven by means of a separate drive system, and the aft propeller is realized so that it can pivot by at least about 90 degrees around an axis, the axis being preferably vertical.

Propeller drive for watercraft

A hull for a water vessel which includes an elongated displacement vessel having bow and stern extremities, a major longitudinal and normally horizontal axis, a vertical and normally perpendicular axis, a length of about L along the longitudinal axis, a propeller mechanism near the stern extremity and a guide vane which is located at a distance of between about 1/4 L and 1/2 L (preferably about 1/3 L) ahead of the propeller mechanism.

Water craft with guide fins

A hull for a water vessel which includes an elongated displacement vessel having bow and stern extremities, a major longitudinal and normally horizontal axis, a transverse and normally perpendicular axis, a length of about L along the longitudinal axis, a propeller mechanism near the stern extremity and a guide vane which is located at a distance of between about 1/4 L and 1/2 L (preferably about 1/3 L) ahead of the propeller mechanism.
