There are many ways of elaborating upon the design and construction of this toy motor-boat, but, having given the necessary instructions for building a simple model, I am going to leave further development for you to work out. Here is an opportunity for you to use your ingenuity. Devise an adjustable rudder, add a keel, finish off the cockpit with a coaming, install a headlight made from a pocket flashlight—in fact, see just how complete a motor-boat model you can build.
