I have a Lewmar size 50 high profile hatch for sale. This is off of a 88 Beneteau First and was replaced to prepare the boat for an Atlantic crossing, otherwise it was not leaking. The rubber seal is in great condition, no cracks or dry rot. The lens is crazed and cracked but it is an easy fix if you have access to a router. This is the highly sought after flush base version that fits onto a cutout regardless of the exact shape and corner radius, making it easy to retrofit to any boat.
$250 plus shipping
