Definitions

  • the invention relates to a device according to the preamble of claim 1, such a device is known from DE-PS 33 07 412.

B. a transverse pin, which is located at the rear end of the fin shaft, as seen in the direction of travel of the sail board, engages with horizontally running grooves in the side walls of the receptacle. The front end of the fin shaft is fastened with a vertically extending locking screw which engages in the threaded bore of a metal plate within the horizontally running grooves. This type of fastening has the advantage that the fin inside the fin box in
  • a further deterioration in driving behavior occurs if the fin shakes or vibrates sideways while driving. If, in order to avoid such vibrations, the fin is held free of play in the receptacle, it can only be inserted into the fin box with greater force due to the parallel side walls of the receptacle. This problem is further exacerbated by sand contamination.
  • Another disadvantage of rigidly attached fins is that the fin and / or the fin box can be damaged in the event of sudden loads on the front fin edge which occur when hitting an obstacle or when touching the ground. The same
  • REPLACEMENT LEAF Disadvantage adheres firmly to laminated fins, which are vibration-free and aerodynamically connected to the sail board. Furthermore, such fins cannot be changed.
  • resilient webs are attached to the front and rear end walls of the fin box and are lockable with semi-cylindrical projections in corresponding recesses in the front and rear end faces of the fin shaft .
  • the fin can deflect resiliently forwards and backwards relative to the sail board, which impairs the sailing properties of the sail board.
  • the side walls of the receptacle here also run parallel to one another, which leads to the difficulties already described with the play-free fin seat.
  • a fin box is known from DE-OS 34 40 553, the housing of which is anchored from the underwater ship in the sailing board through the board body to the deck.
