I started by laminating a couple of 1/8" sheets to a curve I made.
Then I glued edging, boom chocks, and nav light bases on the top, and various pieces on the bottom for mounting and structure.
Finally came sealing with penetrating epoxy, and lastly, paint.
I still have to attach the awning track for the cockpit awning, and the grab rails that I made from a nice piece of jarrah. Incidentally, jarrah is a much better wood for boats than teak. It is at least as rot resistant, but it weathers much better and is significantly cheaper. I'll post a final picture in a couple of weeks when I install it on the boat.
