Right now, you have a slot which is a bit wider than the board which creates
some drag. Most of the keels I've seen are rather flat on the bottom, so you
could build a cover out of aluminum or copper and form it to fit over the hole.
Then fasten it with flat head screws. If you made it strong (thick) enough, you
wouldn't have to use a bolt.. I would put some butyl between the cover and the
keel, to keep the stale water out.
For the bolt if you decide to go that way, (I'm assuming the keel is somewhat
'fat' like the ones I've seen around here) you could use a carriage bolt or a
flat head bolt where the head wouldn't be protruding very much and countersink
the nut on the other side. A little putty would cover the nut and it should be
better than the slot you have now.
Removing the cover would be easier for the next owner than cutting away the
glass.
Our workboat guys around here put copper covers over everything - about 1/16 of
an inch thick - it won't produce much drag. They use copper nails as well, but
I would use screws.
Just an idea.

Gary,
Interesting — How would you bolt through it without affecting the
hydrodynamics of the keel shape? And what kind of cover?
I figure the next owner could always cut the glass open and restore the slot
if he/she wants. No?
All the best,
Edd

If you are sailing almost all the time with the board up, why not just put
a bolt through it and leave it where it is? When, (and if) you decide to sell,
the next buyer can make his/her mind up about using it. You could even fashion
a cover for the slot and improve your performance by getting rid of the
turbulence. I would hesitate to stick the board up in a permanent fashion.
