Maybe I had a special centerboard in my '82 M-15. "Cause unless I'm
getting senile, when I refinished it, the CB contained a steel plate.
At least as far back as I ground it down-- which was a few inches from
the leading edge. 45 lbs? Maybe. But then, everything seems to be
heavier at my age.

Lets not forget that the older pre 1987 M_15s had steel shot for

While most of these boats are fine, a number of them had (over the
years) water intrude into the keel and start
rusting the steel shot. As the steel rusts, the keel swells up and
squeezes the centerboard. All M_15
centerboards pre 1987 also were fiberglass with steel shot inside.
These also could swell up over the years and get
stuck in the up position. The weight of all these fiberglass/steel
shot boards was close to 45 pounds. Never more
than about 47 pounds. All the M_boats after 1987, both in the 15 and
17 have lead instead of steel for ballast material inside the keel
and inside the 45 pound centerboard.
I doubt that Tom has dirt holding the board up. More likely the board,
keel trunk or both has swelled up and is now stuck. Same for you Jim.
Once you get the board out it has
to be made thinner so it won't be sticky. (sand smooth and carefully
remove some of the material on the
fat part).
We use nothing but pure lead. No rust, no swelling.
