A device secured to a submersible portion of a boat lift to stabilize the submersible
portion of the boat lift from unwanted lateral movement. Elongated pipe-like devices
are attached to a submersible portion of a boat lift in proximity to a piling.
The device is mounted to the submersible portion of a boat lift so that movement
caused by wind, wave, or current action that would force the submersible boat lift
into lateral motion will be stopped by the pipe-like device, which comes into contact
with the piling before the lateral motion becomes so large as to be undesirable.
