RE: stitch and glue/ tack and tape consruction?
Conventional "instant boat" construction, i.e. chine logs seems best suited
for the original fleet: surf, teal, elegant punt, zephyr, june bug, etc.
Tack and tape (or stitch and glue) work especially well with multi-panelled
boats like gypsy, nymph and car topper. But the latter method could
certainly be used for any of the original fleet. I've replaced all the chine
logs in the micro I'm restoring with deep, double taped fillets. As a result
the chines are profoundly powerful. I've also tripled the thickness of the
bottom (added a layer of half inch ply to the sole). I'm hoping to launch at
the end of next week, in time for the Mahone Bay Wooden Boat Festival.

I personally think you'd end up with a much stronger hull using that
technique. It's even possible that you could dispense with the chine logs
if the fillet there were large and used several layers of glass tape.
Conventional stick and panel construction creates a "stress riser" at the
corner of the frame/log. The fillet tapers the load out onto the skin and
makes failure much less likely. At least when the Gougeon Brothers wrote
their book on boat-building, there were no "rules" for the scantlings, so
designers tend to be rather cautious and stick with what they know works,
except on very small boats.

Hey folks,
I've never built using this type of construction method untill now.
My micro navigator's pilot house is being built with with 3/8" ply
and is currently wired and i have slopped on some epoxy tabs and and
waiting for it to set so i can pull the wires and tape the joints.
So far i'm impressed with the technique. Could you stitch a micro's
frames to the sides and then stich the bottom to the frames and then
the chines? Maybe this defeats the point of the micro's simplicity
but i believe there are advantages to this type of construction,
expecially if you are filleting the bulheads inplace and glassing
the bottom/chines already.
