If you just want to get back on the water and race legal, then
http://www.apsltd.com/Tree/d90000/e87992.asp , but $318 + shipping seems
kind of steep (and that's not just Annapolis Performance Sailing's price).
Surely you can find someone with a Laser and take photos and measurements.

I would NOT use Plexiglas!!! All the wrong characteristics (brittle, hard
to work, ... ). When I made a new one for my Sunfish, I found a piece of
hardwood at the big box that was not much bigger than the right size, worked
it down, put a coat of epoxy paint, handles, spring, and it's worked well
since. I think it was mahogany, but I'm not sure. Wood is nature's
composite material. (I had my old board and made the new one to match
pretty well -- allowing for the amount I'd ground off over the years.) Oak
or ash would also be good choices.

I picked up a laser sailboat built in the mid 1970's I think at a yard
sale.
It is missing the daggerboard. I'm hoping to make my own but I need the
dimension. Can anyone help.

What would you suggest to make it out of? Would a thick piece of
pexiglass work?

Thanks
