Peter, I would agree on a dodger wind screen. If it broke no water is going to leak any place. For a hatch or for something as large as a hatchboard I sure wouldn't trust it. A wave crashing on a hatch would be more than plexi would take. If you have to put screw holes in it I would never trust Plexi either.

I was replacing a cover for a large dorade box and needed a piece of 1/2 inch material and found a polycarbonate called Markolon. I found it much nicer to work with than Lexan. Lexan will chip and crack if you skip a drill bit on it. You have to be very careful installing latches or screw holes into it.
