This just popped into my mind from something I learned years ago. We spent a week in Colonial Williamsburg and toured all of the trade shops. Something the wagon builder said just struck me as counter-intuitive. They made heavy, cargo carrying wagons as well as small, light personal wagons and buggies. It seems they use the heaviest (and strongest) woods for the lightest vehicles and the lightest ( less strong??) woods for the big , heavy wagons. The rationale being that heavier, stronger woods could be smaller overall and therefore lighter in the long run. Lighter woods could be used for the heavier vehicles and made somewhat oversized to compensate for lesser strength. Put in those terms, it makes perfect sense. How that translates into boat building is yet to be known.........but the wheels are turning.
