So I have completely rebuilt an Infusion and had my maiden sail a couple of weeks ago. One issue we had was with the rubber dagger board shims. Even using shims on both sides of the board they do not hold the board in place. I can't move them further into the board than they already are so now I am wondering what the best fix is. They will have to be bigger, in which case I am not sure where to get the material. Another thought I was having was to sandwich the rubber piece inside of some trailer bunk carpet so that the carpet would be rubbing the daggerboards. Any thoughts or suggestions would be appreciated.
