When I bought my Cal 27 in 1996 the forward hatch had already been replaced. It was made by building a square frame roughly 3 inches high with cross supports and plexyglass cover the opening. It is stong and can be walked on, I would suggest however to make a cover for it to keep the sun from damaging the plexyglass. I will be necessary to form the frame to the deck to disperse the weight when walked upon. Good Luck
