Dave, I too am interested in the length of the M-15 pennant. Although it is O K on my M-15 now, I may need to replace it some day, and knowing the specifications would be useful. You did tell what I needed to replace my mainsheet and traveler when I talked with you at Pocket Yachts in Port Townsend, and like those new lines that I bought from the WoodenBoat Chandlery.

there is no centerboard winch on the M15s. the M17s with M15 centerboards do not have winches. the M17s with the cast iron board have a winch, in the cabin, for raising/lowering the 180lb board.
on all M-boats the centerboard should be suspended by the pennant with the board is down.
there should be a knot on all M15s that stops the board before it over-extends and the leading edge hits the forward part of the centerboard trunk. i can't remember the length from the pennant hole to the knot. if wanted i can go out and measure the distance on the M15 here at the shop.

The trick is once you find how much line to let out on your center board, or some of the other lines too is to tie a stopper not so if it slips out of the cam cleat or whatever it will still stop before it goes into the wash. Steve M-15 # 335

I do get a side to side clunk when the boat is "idling", as in not moving forward enough for the foil to generate lift and counteract any side to side wave action. That will usually be in light air or if you are pinching up tool much and starting to stall. (Almost in irons)
Lifting the board another inch or 2 generally removes the "irritant". As does bearing away and picking up speed. More satisfying too.
It was suggested to me on this board and by the previous owner when I got the boat in 2009, not to let the c/b bottom out. Especially important if you loose your grip on the pendant. I believe most of the early boats ( built by Jerry) have a winch to raise lower the c/b, while the later boats (after 2001?) have a cam cleat, as mine does (2003). Guess having the winch does give more control and less likely to get a drop onto the stop.

Hi Bill, Seems like suspending the board by the pennant would allow for a lot more swing from side to side. Have you found this to be true?

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".

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. Tom B, M17, '77, as yet 'no name'. I think it is waiting until I get it back on the trailer to tell me what it's name is.
