ABSTRACT:
A combination paddle, hook and pump is disclosed wherein the hook is located at one end of the paddle and is contoured to permit smooth paddling action by the paddle. The hook can be rotated from a closed, non-hooking position to an open, hooking position and has a pair of openings therein to permit the pump to either pump air or water into an object or to pump a fluid such as water from a source of the fluid. The paddle comprises a dielectric material that contains metal particles to reflect a radar beam thereby permitting a boater using the paddle in a raised position to be spotted by radar.
