"Make yourself an ark of gopherwood; make rooms in the ark, and cover it inside and outside with pitch. And this is how you shall make it: The length of the ark shall be three hundred cubits, its width fifty cubits, and its height thirty cubits." (Gen. 6:14-15)

A pious shipbuilder in Holland, by the name of Peter Jansen, reasoned that if God had designed the ark, it should be the ideal plan. So he built a ship on the plan of Noah's ark, not as large but of the same proportions. Though it was ridiculed while it was under construction, it was found after launching that it would carry one-third more freight, would sail faster, and was much safer than the old type. And, today, with but little variation modern ships are built on the general plan of Noah's ark. (From Encyclopedia of 7700 Illustrations)
