Centreboard or fin for a sailboard

摘要

In a centreboard or fin for a sailboard, forces resulting in capsizing are to be avoided or at least reduced. This is achieved by virtue of the fact that the centreboard or the fin (1) consists of two zones (top part 4; bottom part 5) which are arranged one above the other with regard to their operating position and can be twisted against one another about a connecting area (web 6) arranged at the front edge (7). <IMAGE>
