A handle for carrying watercraft, wherein the handle also functions to securely retain a paddle or oar, the handle comprising a channel for receiving and retaining a paddle or oar using an interference fit. The handle is secured to the watercraft by a strap attached to the watercraft body and passing through a slot in the handle that runs parallel to the channel.

The present disclosure is a forward-facing rowing mechanical device for on-water paddling transportation equipment. The device is comprised of a novel mechanism which re-diverts effort from legs of the rower to the opposite direction. Therefore, the water propelling direction is changed by the mechanism from backward driving to forward driving. The device includes a backbone; a seat on top of the backbone; a sliding rigger carrying oars; a foot plate for receiving effort from the rower; the effort diverting mechanism for changing driving direction and other necessary peripheral parts.

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.
