Stitch and glue canoe; scarf or butt?
Well, the boat is the bateau.com "cheap canoe," and they suggest a butt
joint, with a block glued over the butt. I think the method suffers a lot
for looks. The joint is right across the fattest part of the canoe, exactly
at the middle. There's added stiffness in the sides from a rubrail, and I
might add a little inwale and a bottom runner, if the taped butt makes me
nervous.

It probably depends also on how the joint will be stressed. If it's in an
area where bending stresses are minimal, it may work just fine. However,
if
it is subject to repeated bending loads, it may eventually fail. Also, if
the joint is marginal to begin with, quality control is critical -- make
sure your production pieces are AT LEAST as good as your test pieces.
A compromise may be to use several layers of tape at the joint,
appropriately beveled, to spread the load further. The final layer of
cloth
over the hull will add to the strength.
