I purchased my Hunter used and I am sorry to say that the previous owner lost the OEM companionway hatch. It was replaced with a piece of plywood that was cut to fit the hole. I want to put in a little more effort and make something a little more original but every picture I see shows little detail here. Anyone who could take some measurements or pictures, anything would help! Thickness, lenth, two-piece(?) joint, etc.PLEASE HELP! Thanks.Will settle for other models too.
