Copying a 31 Bertram in Quepos Costa Rica

[GringoJohn]

Still doing alot of sanding. I have some decent pictures of the interior I'll try to post in a bit. But we started on the top. Used my old 2 inch crown formula to cut some plywood jigs and then line them up:







Then we put some foam on top of them and stuck the foam together with Cabosil.










Then here is the tricky part, we propped up the side so it was flat, and glassed one side. Then we flipped it over and let it be curved like the jig and we fiberglassed the other side. When we fiberglassed the second side, we pulled the foam down with thin wire to the jig. After the second side dried, you can pull the wire out leaving very minimal damage. The idea is the foam with one side glassed is very flexible, but once you glass the second side it will not move at all, and will hold it's shape very well.







And then we put some 3m microglobes on the top part to get some sanding in. Probably jumped the gun a little, I want to make the edges 2 inch thick so it look thicker as a whole, and then we need to make a bump where the radar mounts so we can hide the cable up there. We'll get that done soon. I dig through the phone and see if I can find some cabin pictures...
