unfortunately the companion way hatch was place into the slide before the hood was installed
A fellow h34 owner talked about using a drumel tool and cutting away the fiberglass and aluminum slid at the top of the entrance of the companion way so that the hatch could be removed and then installing stop blocks after installing the new hatch. His second option was to cut the hatch into two halves to remove old one, then fabricate a new hatch out of acrylic in two halves and using acrylic glue, he would cement the two halves back together. He was shower and a glass fabricator by trade. Don’t know if he ever the hatch project or not. He did say that gluing acrylic was not hard to do.
hope this helps
