RC Sailboat Designs
I'm playing around with scratch building an RC Catamaran. Here is a start of the project using some cad software.

I would be carving it out of foam and then fiberglassing over that.

Not sure where I'm going to put the radio gear in if it is carved out of foam.

Would the best way to round the corners of foam be a router or would it need to be hotwired?
