I just replaced all my hatch’s with Lewmar Ocean series. You need the 60 series for the v-berth and the one behind the mast and the 40 series for the one in the galley. I had to trim the fiberglass ever so slightly on the galley one but the other 2 were drop-in. I HIGHLY recommend using Bed-it butyl tape on the install. We’re slipped in Waterford Marina in Houston and didn’t have a single leak during hurricane Harvey.
