Abstract

Next to the rigid part of the keel (10) which is firmly attached to the hull (50) of the vessel (5), the keel (1) comprises a rotatable part (2) which consists of two with each other firmly connected V- shaped foils that point apart and are at least approximately at right angles to each other (21, 22), or two separate in the same longitudinal axis rotatable foils where the angle between them can be adjusted. The foils are around the geometrical axis (100) of the keel (1) rotatably connected to the rigid part of the keel (10), so that each of the foils (21, 22) can optionally be turned from the approximately vertical into approximately horizontal position or vice versa, or held in a certain chosen position. At the free end (210, 220) of each of the foils (21, 22) at least one hydrodynamically designed weight (211, 221) is proposed. On the one hand this type of keel (1) ensures the vessel (5) the necessary ballast for maintaining the vessel's stability and minimizes the vessel's (5) listing around its longitudinal axis (201), and on the other hand enables the vessel (5) to adapt the hydrostatic characteristics to the conditions at the anchorage and its hydrodynamic characteristics while sailing, which improves the efficiency of the sails and increases the speed. Moreover, this kind of keel (1) is solid enough to withstand the weight of the whole vessel (5), which enables the maneuvering of the stranded vessel and optionally also offers support to the vessel on a flat or inclined area ashore, or when sailing at sufficient sailing speeds even the planing of the vessel (5).
