The craft sails smoothly even in shallow water.
The "Butterfly wing" diagram is a scaled down pattern for the boat's wooden components. Redraw the grid, in 1-inch squares, on a 17-by-20-inch scrap of paper, and carefully reproduce the design on this larger "graph."
The rigid frame provides support for the seat and motor.
