Abstract:
A combined paddle and pump can be used to propel a small boat. The handle telescopes with a locking nut that may be loosened to allow extension and retraction of the handle. The handle is hollow throughout and a pair of check valves are provided. One check valve opens when the handle is extended and the other opens when the handle is retracted. When one check valve is open, the other is closed. When the distal end of the paddle is placed within a volume of water, extension and retraction of the handle results in a liquid first being sucked into the hollow interior of the handle and then propelled out of the handle.
