I have started building the hard top for the Rasmus out of ply. I am going to build it in place for the most part. I was going to make a frame out of stainless steel but decided to go with plywood/epoxy/glass composite. I thought the steel frame would add too much weight up top. After looking at measurements sent by Euan and pictures, I have come up with my best guess at the hardtop radius. I am going with a hardtop radius of 122 inches. I will make the top out of 2 layers of 1/4 inch okouma ply bonded with epoxy. Below is the dimensions for making the jig necessary for making the top with a 122 inch radius curve. If anyone out there thinks I am off base on this I would like to hear from you.
