      Fundamentally, the way you determine the
      shape of flat plywood, which will
      curve correctly to fit the boat is to
      break down the surface shape into
      triangles. I think that Sam Rabl first
      described this. See also:

      If you dust off your memory of high school
      trigonometry, you can also do it relatively
      quickly using a spreadsheet.

      In essence, you know the shape of each quadrahedron
      with four corners being:
      station 1 chine,
      station 1 sheerline,
      station 2 chine,
      station 2 shearline.

      Connect corners diagonally to break it into triangles.

      These triangles can then be 'unfolded' into a flat
