Universal keel for all sailing vessels with pivotable, asymmetric keel fins

摘要

The mode of operation of the present invention, in which the asymmetric keel fins can be run either in a so-called keel form or in hull parts provided for this purpose in order to considerably reduce the frictional resistance, can be shown especially clearly on a unit for seagoing transport systems (see supplementary drawing 3). The feature of the free gap according to Claim 1 is naturally omitted through full overlapping, since in reality both asymmetric keel fins are of course pivoted through about 50 DEG to windward, as a result of which, while including the angle of heel, approximately the full weight can act in such a way as to promote stability. (Saving of otherwise necessary water ballast.) In seagoing transport systems (sailing cargo vessels), in each case 1-2 units are not only to produce maximum stability forces in the bow and in the stern, but precise steering movements of the ship can thereby also be carried out without additional resistance on the rudder. <IMAGE>
