Unshimming the Board

We've haven't been able to get much use out of the centerboard since purchasing Owl Moon.  The centerboard and slot has been cleaned and painted twice now.  The problem we have had is it gets jammed up and won't deploy, even when motionless at the dock.  The couple of times we were able to use it, we had to almost stop the boat head to wind to get it to lower.  Paul thinks we need to remove the starboard shim at the top corner of the board where the pennant connects to the board.  It is for stabilizing the board in the slot, but may be just a bit to thick.

The shim was removed by lowering the board all the way and then using a sawzall along the edge of the board to cut the fasteners which held the starboard to the centerboard.  Now there is a bit of wobble in the board, but it will stabilize once it is loaded with water pressure under load.
Here the centerboard is lowered and the shim is just inside the centerboard slot ready for the sawzall.

Shim successfully removed.
