Plywood
Most of the PT boats that served were made up with 2'' thick mahogany planking that was laid up on the diagonal and planked for and aft . It was referred to as "ply wood". not the same plywood purchased today at lumber yards. They were not veneers glued up but there strength was the 'cross planking" method of mahogany. Visit Battleship Cove in Fall River MA and see the process.
