This is the fastest way I can think of to build a class legal Puddle Duck Racer.

The Bill of Materials for the hull is:

  • (2) 8' 1x12 - sides
  • (1) 8' 1x10 - bulkheads
  • (1) 8' 1x8 - transom and stern
  • (1) sheet 3/8 exterior plywood - bottom (you can use 1/4 or 5.2mm if you add skids)
  • (1) sheet ¼ or 5.2mm exterior plywood - decks and other components
  • (1) 12' 2x4 - mast

And depending on how you put things together, you'll need more wood for skids or foils, tiller, rudderhead, etc.
