Back in October, 1971, I wrote about the plywood, 12' two man Australian speedster, the Gwen 12, I mentioned I had in my possession a set of double bottom plans from the 1970's, courtesy of Aussie Andrew Chapman. I present them below. As always it is best to view this PDF file in another tab; click the arrow icon on the top right of the view box.
I think if I was to build a Gwen 12 in the U.S.A. I would glom a 420 rig onto the hull, particularly the non-class legal fat-head main that the collegiate programs seem to be now favoring.
TOH to Andrew Chapman for sending these along.
