fixing the dagger board

Yesterday we did come to the conclusion that the dagger board did not go down the full length. The water slot in the case must be the problem, I could not test this during the build because my shed was not that wide. Today we lifted the boat out of the water to see were it could stuck. With the power sander we sanded some of the edges were there was not room enough. After that the dagger board  could be pulled down completely, from the bottom to the tip is 1,77 meter. The top of the waterline to the bottom is 48 cm. We  now can calculate later the reel depth.
