Tom, I suggest that you mark or knot the centreboard pendant line so it stops just before "bottoming out". Will save any potential wear/damage on the surfaces that touch when lowered to the limit. You also won't have to deal with the " last thunk". Bill

Now that I have the board out, it looks like the diameter of the notch that stops the board from go down too far on my 17 is large enough that I can slip a dense rubber sleeve over the thru bolt that catches the notch in the board. That should relieve that last "thunk" when lowering the board which has always set my teeth on edge. A second consideration, since the board was also deeply grooved on both sides where it worked against the bottom edge of the cb trunk when fully lowered is to adhere some sort of vinyl sweep on the bottom inside edge of the cb slot. The vinyl sweep should be easier on the bottom paint on the board and should mitigate the side to side action of the board in the slot. By placing the sweeps right at the bottom of the cb truck they should also help with the slot turbulence. No? Nice to have a situation like this to chew on at four in the morning.[?] Tyler's idea about using cutting board material merits further consideration also. Good idea.
