...and don't overlook the fact that the Ark had to be loaded an balanced properly. Noah and his family, coming from such a long and distinguished line of seafarers would know exactly how to load the solid food, potable water and heavy and light animals in such a way as to maintain proper trim throughout the voyage. And, of course, they had all the necessary ground tackle, ropes and bindings to secure the food and animals in the worst possible sea states. Uh-huh. You bet'cha.
