Abstract
This invention relates to a device and method of reducing the azimuthal torque acting on a pulling pod unit or azimuth thruster (1) having a rotary pod housing (4) with a substantially vertical slewing axis (3A), a propeller (7), and downwardly directed fin means (6) carried by the pod housing (2) abaft the slewing axis (3) adjacent the rear end (41) of the pod housing (4) wherein two downwardly directed fins (6) are positioned a distance (δ) apart, one on each side of a longitudinal plane (30) through the slewing axis (3A), on an aft part (40) of the pod housing (4).
