Thanks to Heriberto, I just received a copy of this in the mail. It cost, even used, a pretty penny (what's a penny anyway?), at $30 US nearly double the price stated on the back cover. And starts at (gasp) $110 new at Amazon. Still, even at 3/16 inch in thickness, it's densely packed with information and photographs (B&W only) and makes a perfect companion to Sail & Rig Tuning. © 1994 it's nearly 2 decades old, but generally seems fairly current. It focuses mostly on 5O5, I14, 420, 470 and FD designs.
RIg your Dinghy Right. It has tons of line systems and innovative methods of fitting. Many of these systems would scale up with modern lines, equipment and with the hipro sail systems that have scaled up from planing dinghies. Excellent book!
