Re: [bolger] Windsprint (scaling up from the Teal)
The scantlings are fine on the Windsprint. I've never even wondered if
the 1/4" plywood was adequate on Otter
(http://www.patrickcrockett.com/boats/index.html) -- it has always
seemed quite strong enough to me. I used to worry about the yard
snapping when the wind came up, but after 10 years of no mishap, I quit
worrying about that.
I did break a rudder in half and broke the rudder stock in half. The
latter was due to a void in the plywood. I used marine ply for the hull
but cut corners with the blades. Not a good plan as it turned out -- the
stock broke as we were careening toward a group of kayaks at the MASCF,
and the rudder folded up a few years later as we were trying to maneuver
out of the way of a ferry.
You can definitely trust Bolger to design a strong, safe boat. (I would
not have had rudder problems if I had built to the design.)
There was a Windsprint with a leeboard at the MASCF one year. Wind
didn't blow hard enough that year to really test it, but I think it was
probably fine. Looked easy but not quite as attractive. The daggerboard
is definitely a pain in shallow water -- you have to pay attention to
how far you are from the edge of the channel. On the other hand, having
the well on the side of the boat opens up the interior and makes for
uncomplicated structural engineering.
I would recommend 2-part purchase on the sheet. Bolger drew a single
part sheet and it was unpleasant to hang on to in any wind at all.

- I probably should keep my opinions to myself because I'm not that much
of a builder, but....
Bolger himself has noted that some of his boats are strong enough, but
maybe not as strong as desirable, depending on what the user wants.
For example, he wrote than the side of the Thomaston Galley would
weave in and out a bit under sail, and he has written that the Folding
Schooner would be better built of heavier stuff if the user could
handle the extra weight in the folding operation (perhaps with some
sort lift arrangement).
My Cynthia J. was 3/8 and the hull was plenty strong, but one of the
seats broke when I stood on it after a couple of years. This is a flat
piece of ply with 1x2 framing.
The lesson I take is that the specified sizes are good enough, but you
don't want to skimp on the quality.
