International ClassB63H 016/04AbstractA paddle for a narrow canoe or kayak-type boat has a crossbar the end portions of which extend downwardly to create an inverted U-shape, with the blades being at the lower ends of U. Handgrips, preferably including either forearm rests or wrist rests for the tops of the forearms or wrists as well as handgrips, enable the user to operate the paddle in a broad sweeping motion, with both blades being inserted into the water and pulled back simultaneously, eliminating the yaw effect of either double-ended kayak paddles or single-bladed canoe paddles.Field of SearchOSCILLATING PROPELLING MEANSFishtail motion propelling means Flexible OPERATOR POWERED DRIVE FOR PROPELLING MEANS Rocking watercraft Fluid pump Having reciprocating pull cable Sliding handle or pedal Rotary cranking arm OAR OR PADDLE Articulated sectional oar or paddle Having gear Support Having outrigger Canoe or kayak OPERATOR SUPPORTED MANUALLY ACTUATED TYPE Fulcrum support type (e.g., oar, scull, etc.) | |
