Abstract
The invention relates to the provision of an easily operated maneuvering device for sailing boats, which gives the boat in question a maximum of maneuverability also at low travelling speeds and without causing any flow resistance worth mentioning in connection with higher speeds. The device essentially comprises a rudder positioned in the stern of the boat and exhibiting a propulsion apparatus, the power direction of which coincides with the vertical symmetrical plane of the rudder.
Claims4
Maneuvering device for sailing boats comprising a rudder, and propulsion means comprising a propeller unit and driving means therefore incorporated in the rudder so that the propulsion effect of said propulsion means relative to the water surrounding the rudder will be substantially directed along the vertical center plane of the rudder, said propulsion means being incorporated into a separate unit comprising a readily detachable insertion part of the rudder having a shape following the form of the rudder, quick coupling means for connecting said insertion part to the remainder of the rudder and for the removal of same, and a separate piece also having a shape following the form of the rudder and quick coupling means for connecting same to the remainder of the rudder, whereby said insertion part can be quickly substituted by said separate piece to fill the space left by said insertion part when the latter is removed, and said insertion part and said separate piece when connected to the remainder of the rudder cooperating with the latter to make a complete rudder having smooth side surfaces and a very low flow resistance.
