Unitary aluminum watercraft and method of production of same

摘要

A unitary aluminum watercraft is constructed from a single sheet of deep-formable aluminum by forcing a mold into the sheet to imprint the mold into the sheet and then forcing the perimeter portions around the mold. Excess sheet material is removed and than placed into a replica mold. A deck is installed and bonded to the interior bottom surface of the body by a structural flotation foam, such as urethane, to form a unitized structural beam which eliminates the need for a keel and the accompanying structural ribs and below-waterline rivets usually required.
