Last summer the window on the deck hatch that allows the board to run up and down cracked. The window appears to be glued into the hinge and latch hardware. Has anyone ever replaced this? Is it time to purchase a new hatch? I can see a Lewmar number on the window, but I've not found anything on the Lewmar site. Or maybe I can heat up the glue, remove the old parts and fashion a new window from some Lexan or something like that? Has anyone had any experiences with this?
