To the right shows the radius for the roof over hang in preparation for the combing I will add. It will be canted back 45 degrees in the front and 10 degrees on the side. I have added two longitudinal exterior beams on top of the roof to add stiffness, and act as rub rails for a dingy. The fender washers and screws are used to clamp the beams in place while the epoxy sets. You can also see the scarfed areas in the 1/4’ ply.
Below: the exterior beams can be seen along with a lot of unwanted fairing compound due to the epoxy going off before I got the foam set in place. The roof’s 10’ span doesn’t flex under my weight of 200 lbs.
