Apparatus for heel-free wind propelling in particular the watercrafts

摘要

The device according to invention serves to the lurch-free wind drive, particularly in the sports, recreational and touristic yachts, in the water craft for the transportation of passengers and goods, and in the cradles with special skids equipped in the lateral resistance plane. The device includes the extension arm (2) rotationally connected with the main hull and resting by means of a transverse spar (4) on auxiliary hulls (5 and 5') as well as on the driving surface (1) placed in it. This surface is inclined to such degree that the force of wind passed at the height of the lateral resistance of the main hull without provoking a heeling moment. The device can be safely used even for very large driving surfaces. The attainment of high speeds is additionally facilitated by the action of the driving force unloading the main hull. A very efficient steering of the main hull is designed by changes of the auxiliary hulls' situation as well as of the bow rudders' situation placed on them.
