Question 117General Subjects - 1st Asst/Chief

The correct answer is C. A constant-tension mooring winch is designed to automatically render (pay out) and recover (haul in) the mooring line using the prime mover (the engine or motor that powers the winch) when the mooring line tension varies outside of narrow preset adjustable tension limits. This allows the winch to maintain a relatively constant tension on the mooring line, which is essential for secure mooring in varying environmental conditions. The other options are incorrect because they do not accurately describe the full functionality of a constant-tension mooring winch. Options A and B only describe the rendering (pay out) behavior, while option D describes the recovery (haul in) behavior, but none of them capture the complete automatic rendering and recovery capabilities of a constant-tension winch.
