Evelyn will be double planked. In essence, her hull is planked twice. The first layer of planking is made from approximately 400 narrow mahogany pieces (strips) 1 3/4" wide by 5/8" thick that run from stem to stern. Each piece is fastened with bronze screws to the frames and backbone and glued to the adjoining plank. But before all that, you've got to start making strips. Episode 3 shows just the first. Future videos will show the complete process from selecting lumber to hanging a finished strip plank.
