M_Boats: Winch re-leveling

Hi Folks, the winches on my M-23 are too slanted and it makes the port side winch over ride. Always. I do not know why they set them up at these angles, I have noticed that this seems to be custom to my M-23. But since it does not work I want to level the cockpit coaming so that the winches are at a more normal angle to the jib sheets. One idea was putting a wood trim board on the coaming but a more conservative approach would be just filling in the dent that was formed in the coaming but I am not sure how this would look cosmetically unless it was done with wood. Does anyone have some suggestions? Thanks Robbin
