What a coincidence, I just finished the plans for mine. I traced the plans in cad and scaled them up to the size I wanted. I plan on making this a summer project this year.
but in my opinion a butt joint is much stronger.
I already have a canoe & a pirogue to go if I "have" to.
I wanted to be a project for me and my dad to work on. He'll turn 70 in May and we hadn't worked on a fun project in a while.
He was diagnosed with cancer a couple of years ago and is now in the tail end of his treatment. He would want me to wait for him.
