Intend to use Lewmar
I installed a Lewmar Ocean 60 hatch on my '83 H25, and love it. I want to install the matching smoke-gray ports, and according to my measurements they should fit well. I can't provide more than encouragement at this point. Unless I move up to an H25 or 30, I will be installing the Lewmars soon. Let us know "how you done it" if you go for it before I do.Randall
