A side stabilizer and a wind-powered vessel incorporating same is designed in a way that both lateral sides (1) of the vessel's hull (2) are equipped with at least one fin (3) positioned above the waterline if the vessel is fully loaded and stationary. A preferably flat shaped fin (3) obliquely rises in relation to the waterline (4), so that the distance between the part of the fin near the bow (5) and the waterline is bigger than the one of the fin part near the stern (6). Both sides (1) of the vessel (2) are equipped with at least one (3), preferably two (3 and 3a) longitudinal fins. When a sailing boat is in its upright position and fully loaded, both fins are entirely above the water surface (4), but when it starts heeling or leaning according to its longitudinal axis (9) the fins on the lee side of the vessel partly or completely submerge. That is how they provide additional hydrodynamic buoyancy that balances the vessel. This kind of device or utensil reduces the vessel's transversal listing which the vessel is exposed to due to side wind force, which results in improvement of the efficiency of the keel weight (7), better buoyancy of the vessel's hull, better wind force efficiency and consequently faster sailing. When sailing with the wind and approximately crosswise to wave direction, the utensil stabilizes the vessel's longitudinal movement since it reduces the vertical movement of the bow (5). When attached longitudinally to both sides of the hull, the side stabilizer fins additionally protect and strengthen the skin of the hull. |
