I have a 2003 (?) H216 and I love it. I had a companionway crack for a long time. It would close up when hot so to repair it, follow the ACP repair instructions, but try to do it when the hull is hot and the crack is closed. No big deal if you are ready to bite off a repair with fiberglass. You have to use the right resin...I suggest you buy resin from a dealer. The Fusion brand white spray paint from Ace Hardware is almost an exact match.
