ABSTRACT:
On a body, for example a stabilizer fin or a rudder blade on ships or the keel fin on sailboats with a keel, which is fastened to a support body, preferably a ship's hull, so that it projects outward, several ribs are fastened so that they project on the exposed end of the body. These ribs are located at some distance from one another and are parallel to the plane of symmetry of the body. The length of the ribs is approximately 1/10 to 1/20 of the length of the body, which eliminates or reduces turbulence which occurs at the end of the wing like structure.
