Rubber Band Powered Boat

This boat is one of three of the models using a rubber band that I created after a few tries and I tried to put weight on it by using coins and weighing approximately 32.77 grams (https://www.youtube.com/watch?v=fsYgb2xobzQ).

Website address of this model comes from this address: http://blog-imgs-49.fc2.com/b/o/a/boat328/Boat-Blue-Prints-3.jpg, then I cut it a little so that the flat part and can be printed, the middle there are 2 pieces of support that can be broken also to reduce the weight
