I think they are similar in most respects, except that the M15 doesn't have the stopper pin. On that one, you tie a figure 8 (or other stopper) knot in the pendant, and the centerboard hangs from that. Without the stopper knot, the centerboard drops down too far, and eventually gets into a position where one part leverages against another and breaks off a part of the board.
And of course the 15's and newer 17's have a lead weighted fiberglass board, vs. the older 17's shown on the site below, which is cast iron. Interesting that on the Rhoades site, they go over all the keel options for trailerable boats, and come up with the same design as the M15 and M17. Except they use a diamond shaped keel. I'd love to see some performance tests done to see what the difference in lift is between the two designs.
