The board is out of the boat and in the workshop. Here is a photo of the top of the board. The curved outline of the original board is visible under the new piece of timber that has been glued on. The new timber matches the shape called for by the plans. The origianl pivot pin hole has been filled in and the correct centre of the hole marked by the crossed lines. The new holes will be drilled and the tops part of the board re- fibreglassed and painted. Hopefully, the modified board will swing down to its correct position when it is put back in the boat.
I have also made a new tiller arm to replace the straight short original arm. I'm hoping that the new arm will allow me to sit further forward in the boat and that this will help with maneuverability in light winds. Here is a photo of the new arm in position.
