: That's something I have thought of but have not had the nerve to
: try. Plexiglass is going to quickly scratch up. Maybe you can
: get some lexan. Bake it in the oven slowly to make it pliable,
: then form it to the curvature of the hull. I would put a couple
: of wood strips running along the keel line across the window as
: a sacrificial rub strip. I also would gasket it and screw it in
: so it's replaceable yet waterproof. The only sucky part is if
: all this fails you have a boat with a hole in the wrong end. It
: would make rolling easier- just roll over, pop your head through
: the bottom hole, and keep paddling! :-)

I recently made a Lexan / Polycarbonate wind deflector for my car.
It's much more durable than Plexiglass / Acrylic while being more flexible,
and much easier to cut ... much like HDPE in that regard.

Lexan does have the potential to yellow over time vs plexiglass, and is
less scratch resistant than plexiglass.

Below is a Link showing my completed plastic wind deflector / windscreen. There is
also a video at the link showing a durabilty comparison between the two plastics.
