: 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! :-)

You assume there are bulkheads of floatbags! Otherwise you'll be wearing a kayak tutu.
