what would be the best way to make a duct tape boat?

i saw them make one on mythbusters today, and i got to wondering, how much overall would something like that cost, what building methods would be best, and what designs it would be best for?

1) make a design out of cardboard
2) cover it with duct tape

to calculate cost, simply divide the surface area + fudge factor by the price per square foot for duct tape.
