You don't need notches for the sheer, it goes on the outside of the
planking. But you must have them for the the log. It's pretty easy to
get them close enough. I used hand saw to make sure I went slow
enough to do it right.(Well, pretty right. Right enough.)

This varies from boat to boat, but in general, I would say that the
longitudinals are there to provide the tensile and compressive
strength to keep the hull from hogging, and whatever the opposite of
hogging. When you are aground on a rock midships, they keep the ends
from drooping fore and aft.

But, you are right that they are not there to transfer force from the
frames, and attachment to the frames is optional.

In building Bolger's Light Schooner, thinking about cutting out the
notches at the corners of the frames to take the chine logs and sheer
clamp, I am wondering how important it will be to cut the notch precisely
and get an accurate and snug fit for the logs and clamps.
It will clearly involve a lot of tiddly work, grinding and and filing, etc.
It seems to me that a sloppy fit- a slightly oversized notch- should not
harm the strength of the hull. Is it not true that the logs and clamps are
basically to attach the topsides to the deck and the bottom?
What think you?
