I was worried about enlarging the hole in the cabin because there’s quite a bit of curvature but it worked out OK. This is the original portlight. One of the dogs was broken on this side so it didn’t close properly and was a source of water entry. The starboard side portlight had a crack in the glass. I saved the old parts, someone could probably make one good, original portlight from the old parts. Hit me up if you need them.
