I Need to Build A Styrofoam Boat? What is a design I could use to Make it go as fast as possible?

Question

What is the design I could use to Make it go as fast as possible? I can only use a sheet of styrofoam that is 30cm by 30cm. I have to propel the boat by using 2 candles that will heat up water in a test tube, which will propel the boat forward. I am allowed to use the styrofoam sheet, glue and popsicle sticks. How should I make it? Thanks for your advice.

Answer 1

Make it 4 times as long as it is wide, with a pointed bow and square stern. Use a few Popsicle sticks as possible as they add weight.

If you need to make it wide, then make a catamaran design-two hulls with a deck over all.

Make certain that the steam exhaust is in the exact center of the boat.

Dan

Answer 2

Look in boat racing books or magazines and find a hydro-plane. When you really look at a hydro-plane there is not to much to them. Very simple design. Hydro-planes can go in excess of 250 M.P.H.
