Does anyone know how to make a homemade boat or any sites that help? i need to make a boat "model" that is about 1 ft by 1 ft by 8 inches for school and it has to be powered WITHOUT a motor or any electrical device....o and no CO2 cartridges either... i saw some balloon boats but my boat needs to go fast and stay in a straight line. the competition will be INDOORS so i cant use a sail...i was thinking of using a baking soda and vinegar to bottle up the gas and then have it shoot off...yea its pretty hard...thnx in advance!

I think your idea is good, you will have to test it but it is promising. The only problem you think you have is shutting it down, well:
put the soda in a close chamber, with two plugholes, one plughole will be the gas outlet and the other will be vinegar inlet. The vinegar will be in a separate bottle, connect the bottle to the chamber with a tube with a valve or rubber pipe you can press on and stop the vinegar flow and you have your gas generator

Try a rubber-band drive on a side-wheel paddleboat. Possibly rubber-band on a sternwheeler, depending on how you intend meet your dimensional requirements. Any attempt at using a spring-driven screw propeller will be difficult, as the screw creates a yaw that varies with speed. As the spring winds down, the turning force diminishes, so any preset of a compensating rudder would need automatic or remote adjustment.
Start early and play around. I cannot see in my mind how to rig the paddle braces or rubber bands.

Please tell us what or where you plan to boat with your 'banana boat'. The kind of construction you are planning often proves disastrous.
