Hi David, In addition to what Dave Scobie said I have been able to free my board up by diving under with a snorkle and mask and wiggling the bd. You can only grip about 1/4 inch of the board and it may take 15 - 20 dives before it starts to come free. My M15 is also a 1984 or so, maybe an 86. Hull number 310. I finally discovered that it was jamming up due to little rocks dropping off of my shoes and washing down the cockpit drain with the board up. The drain is through the CB trunk and the little stones would jam between the board and the CB wall when trailering. The CB fit in the trunk is very close by design and you cannot actually see a bulge in the trunk wall. You should make a wooden gauge and run it through the CB trunk once you get the board down. I can't remember the exact size of the opening but maybe Bob Eeg or Jerry can refresh my memory. I did end up sanding a little gel coat off of both sides of the board to make it slightly thinner for a looser fit. The board does rattle a bit under certain wave / angle of attack situations.

I live in East Granby, CT and usually sail out of Guilford on Long Island Sound. I have yet to get out for a sail but am hoping to be able sometime in October. Does anyone know if 1984 M-15's have steel ballast in the keel, and whether the centerboard is fiberglass. Mine is well and truly stuck in the up position despite a couple sessions of doing everything I could think of to lower it, and I'd like to understand better what I'm up against. Also, is it allowed to post a boat for sale in this group? (Not the M-15, but my last boat) Thanks very much.
