Abstract
A paddle apparatus for standup paddling of surfboards or like water craft, having a plurality of hand grip portions rotatably mounted relative to the paddle shaft, and a means of paddling whereby the operator can ergonomically paddle with greater power and control on either side of the water craft without breaking either hand grip. A further improvement includes using the handgrip in the position perpendicular to the paddle shaft to determine the blade position by feel and steer with greater torque. An alternative embodiment includes rotation of the grip itself, further reducing the twisting of the wrists and other joints.

An ergonomic handle system for human propulsion through water using paddles or oars having a shaft having a first end and a second end;
- each first and second ends having a paddle blade;
- a plurality of pivot mounts located at predetermined positions between the first and second ends;
- the pivot mounts comprising a first pivot connector being associated with a grip and a second pivot connector connected crossways through the shaft and associated with the shaft.
An ergonomic handle system for human propulsion through water using paddles or oars having a shaft having a first end and a second end;
- each first and second ends having a paddle blade;
- a plurality of pivot mounts located at predetermined positions between the first and second ends;
- the pivot mounts comprising a first pivot connector being associated with a grip and a second pivot connector connected crossways through the shaft and associated with the shaft;
