An improved tiller restraining device is provided for attachment to the underside of a boat's tiller to selectively control the position of the tiller and rudder. The device features a specialized mechanical clutch that grips or releases a control rope, which runs through the clutch and is secured across the cockpit. The device is operated with one hand by moving an integrated clutch lever upward to release the rope and allow free tiller movement, or downward to engage the rope and restrict tiller movement. Inside the device, a spring acts on the lever to pinch and bind the rope against the openings where the rope passes through the clutch housing. The spring and lever are aligned so they toggle, enabling the clutch to remain either engaged or disengaged with no additional controls.

A capture block assembly prevents unauthorized removal, swapping, interchanging or replacement of shackle members used with conventional wire rope sling assemblies.
