The final design of the boat may change. Use any RC system and ensure it can power a motor of several thousand RPM. The boat is 26" long and 12" wide. The depth of the top part (where the RC system and batteries are kept) is 5" and the depth of the lower part (where the camera goes) is 5" as well. The angles of the ends and bottom are 45 degrees. Cut all pieces at right angles and glue with acrylic cement followed by sealing with aquarium caulk (bathroom caulk is not designed to be continuously wet and therefore will lose its sealability).
