Foamboat construction

Step 9 Fullsize P01 revealed

Excess foam carved away, yielding smooth, curvaceous, symmetrical, repeatable 15-foot solid mold for hull. In actuallity, the foam carving process is done in two steps. First, the hot wire is run lengthwise so the wire runs along only one edge of each piece of wood, in turn, to make all the edges visible. That leaves not so much foam left to be cut away in the final step, and it reveals all the edges, which makes keeping the wire running along two pairs of adjacent edges, in the final cut, easier to do. About the only mistake that can be made in the final cutting is that the wire is lifted off one edge, and that will merely leave excess foam, which can removed with another pass.
