VESSEL WITH ROTATABLE POD

摘要

A vessel and a method for driving a vessel. The vessel is provided with a pod arranged at the rear side thereof which is arranged rotatably with respect to the vessel. Rotation is effected about an axis which deviates slightly from the vertical. The axis of the propeller shaft forms an angle which is smaller than 90° with the axis of rotation of the pod. As a result of this combined positioning of the rotation shaft of the pod and the positioning of the propeller shaft, the axis of the propeller shaft with respect to the horizontal will vary when the pod is rotated depending on the rotation position of the pod. This permits optimum adaptation to the various operating conditions of the propeller position.

1. Water-displacement vessel (1) comprising a hull with a longitudinal axis (15), comprising a bottom and comprising a pod drive (2) arranged close to the bottom, said pod drive (2) being provided with a housing (4) containing a propeller shaft (5) which protrudes through the housing and to which propeller shaft (5) a propeller is attached at a propeller end, and a drive for said propeller shaft, which propeller shaft (5) defines a first axis (7), which housing (4) is rotatable with respect to the hull between a rearward position and a forward position about a rotation shaft (9, 29) which defines a second axis (12, 32) which is not vertical and forms an angle (α) of 40°-90°, preferably between 60°-80°, with the first axis, characterized in that an annular jet pipe (17) is arranged around the propeller, comprising a peripheral edge (11) which is at a distance from the propeller shaft (5) and is situated further below a predetermined waterline in the forward position than in the rearward position, wherein the direction of rotation of the propeller shaft (5) in the forward position is adjustable in such a way that the jet pipe has a water-suction effect.
