On the basis that time spent in studying designs is never wasted, I've just downloaded all the drawings. Except for two - the link "joiner sections" takes me to the wrong place, and the link "stemhead fitting" leads to "not found".
You're right, Jim, this design would be so labour intensive to build that it would be uneconomic compared with most more modern designs. Many of the details could be simplified, though.
That said, if I were looking for a sub-30ft boat to enter the Jester Challenge, and had just won the lottery, this just might be the boat that I would want to get someone to build for me. The lines are sufficiently Folkboat-like to make her a good choice for beating to windward across the North Atlantic. But if I hadn't won the lottery, I would be extracting the essence of the design, and working up a new design with a multi-chine plywood hull and deck.
