I had promised Richard I would include his catamaran dinghy in the blog and post about it while he builds it. Well he has been at it full steam and is getting ready to paint the hulls, while I've neglected to take the series of photos necessary to document the build.
Here is a photo of Richard prior to glassing one of the hulls. Afterwards he did some tests and decided to use 4 oz. cloth in 5 layers to cover the bottom of the hulls, which is a foam build up with a nice vee bottom shape. One problem he encountered was air bubbles forming under the glass due to gases expelled as the hull heated up in the warm sun. He solved that problem by injecting epoxy into the air bubble voids with a syringe. He had to drill tiny holes, one in each air bubble. I think he was exaggerating when he said there were 600 bubbles. Maybe not.
We did some research on how tight a corner fiberglass can bend and one answer by Chris Kulczycki was "about 1/4 inch radius, the diameter of a fountain pen or small cigar". A tighter radius, or no radius, causes the glass to lift if it can't bend around the corner.
