I've recently been doing a comparative study of ancient Sumerian mythology relative to the book of Genesis. I am curious if there is a way to explain mathematically why a circular, square (cubic) or rectangular boat might be more or less viable than any other hull design. Specifically, can a person use an understanding of geometry and trigonometry to explore the angle of vanishing stability beyond which a vessel cannot heel without capsizing.
I am curious why flood mythology uses each of these boat designs and if one is more stable than the others or if all designs are unstable.
Any suggestions?
