Well, the M centerboards are similar in that they both drop out of a trunk located in the ballasted shallow draft keel, but how they lower/stay in the lowered position/raise is very different. The M15 is simpler and lighter and is lowered/suspended/raised and suspended in the raised position with a pendant. A knot in the pendant keeps the cb in the proper, lowered position.
The M17 cb is heavy and requires the assistance of a winch (or heck, a good wench will do the trick too probably) to lower/raise. The M17 cb is kept in its proper, lowered position by a tang that contacts a stopper bolt--the pendant is only used to lower it and raise it and secure it in the raised position. There is probably no more discussed topic (aside from towing vehicles and outboard motors) in the M archives--search them for more info.
