Simon's spar is even stronger because of the bend!

That's right, folks! The neutral axis for tension and compression due to
bending has been moved off center, when stressed, more of the boom is in
compression rather than tension. The mid center joint means nothing with
such a clever and knowledgeable repair!

Excuse me but I believe you are wrong because of the direction the boom is
bent. For it to be "stronger" it would have to be arched up in the middle away
from the pull of the mainsheet and vang.
