You'll wind up with a sharp spot in the bend where the wood is weak. Consider too the impact of having poor-quality material in the construction of your boat. Think of the time you'll have invested in getting set up to saw, drying and milling the blanks, then bending each one. Sawing your own wood for a project can be a really rewarding thing, but not if you jeopardize your project by working with stock that isn't up to the task. If your mind is set on milling your own lumber for this boat, then I would suggest that you do like the last posting suggested and sell the logs for firewood, then take that money and buy some nicer logs to mill yourself.
Logs are cheap compared to milled lumber.
You could still mill yourself, I just think you're using the wrong logs. I have a much clearer idea of what I am dealing with now. Then I will pick the biggest, straightest oak and see how it goes.
