Abstract
In a shallow water anchor of a parallelogram design which lowers a rod down from a fishing boat into contact with the ground to keep a boat from drifting out of a chosen location, a depth the rod can reach depending on the combined extended length of the unfolded parallelogram and the length of the vertical rod, a first improvement to increase the maximal depth without concomitantly increasing the length of the parallelogram frame, the improvement using the relative motion and geometry of parallelogram parts to lengthen a telescoping rod, and a second improvement of a flexible coupling to an electric drive motor.
