The Book of Ether, in the book of scripture entitled, “The Book of Mormon” tells of a group of people called the Jaredites who travel from the old world to the new world (or the American Continent) in special barges that the brother of Hared had learned to build, from the Lord Himself. They weren’t built like boats had previously been built, but were “tight like unto a dish”.
Ether 6:7 And it came to pass that when they were buried in the deep there was no water that could hurt them, their vessels being tight like unto a dish, and also they were tight like unto the ark of Noah; therefore when they were encompassed about by many waters they did cry unto the Lord, and he did bring them forth again upon the top of the waters.
Think of the Alvin Maker books (Seventh Son, Red Prophet, Alvin Journeyman etc.) and how the wood was actually, physically fused, like metal, or grew together, like living wood...
Read those books. Pretty ingenious.
