These pictures of the gas locker lid show it raised 24 mm from the deck and also how the coamings fair into the locker lid. I have a matching raised section on the starboard side. The gap from the transom to the lid is to leave clearance so the lid clears the pushpit supports.
While the boat trimmer was measuring up for bunk mattresses and settee seats I was busy measuring up doublers for under the deck where holes have already been drilled for fittings. The ten backing pieces have been located from the dwindling pile of plywood offcuts and have been sawn roughly to size. That is tomorrow’s job.
