ABSTRACT:
The present invention discloses a device for restricting the movement of a hydraulically actuated rudder assembly on a large ocean-going vessel during failure of the hydraulic system. It comprises a half-collar made of a material that is substantially incompressible along its lengthwise axis and is adapted to fit over a ram rod or a guide rod in a steering assembly between a cross-head and a ram rod sleeve or guide rod. The length of the half-collar is minimally less than the length between the cross-head and the terminus of the ram rod or guide rod when the rudder is in a neutral position.
