Abstract
A propulsion mechanism to propel a watercraft through water comprises paddle bars pivotally attached to a support at a first pivot, the paddle bars having a handle at a first end and a paddled second end. A paddle is pivotally attached to the second end of each paddle bar at a second pivot. When the mechanism is operated through the power stroke, the second pivot end allows the paddle to be supported by the respective paddle bar and to be forcefully driven through the water. When the power stroke is completed, the paddle is permitted to pivot about the second pivot and to disengage the respective paddle bar as the mechanism operates through the return stroke.

A propulsion mechanism to propel a watercraft through water, wherein the mechanism is operated through a power stroke to propel the watercraft through the water, and through a return stroke to return the mechanism to a starting point of the power stroke, the mechanism comprising:
- a) a first bar member pivotally attached to a support at a first pivot;
- and
- b) a paddle member having a first end and a paddled second end and pivotably attached to a distal end of the first bar member at a second pivot,
- wherein when the mechanism is operated through the power stroke, the first end of the paddle member is directly engaged with the first bar member, and
- wherein when the power stroke is completed, the paddle member is permitted to pivot about the second pivot and to disengage the first end of the paddle member from the first bar member when the mechanism operates through the return stroke.
The mechanism in accordance with Claire 1 wherein the first end of the paddle member is weighted.
