Concerning a conventional mooring winch, what statement is true?

Correct Answer: Option C — A high capacity brake is required to hold a load approaching the breaking strength of the mooring line, but it is required to slip at a lower tension to avoid mooring line breakage.

Mooring winch brakes are designed to hold loads near the line's breaking strength but must slip before the line reaches its ultimate tensile strength. This protective slippage prevents catastrophic line parting, which could cause dangerous snap-back hazards to personnel on deck during heavy weather or surge conditions.
