🔍 Key Concepts

• Mooring winch brake design and how it protects against line failure • Relationship between mooring line breaking strength and brake holding/slipping load • Why controlled slippage can be safer than no slippage at all

💭 Think About

• Should the brake be designed to be stronger than the line, equal to the line, or slightly less than the line’s breaking strength? Think about what happens if the line parts. • In a heavy surge or vessel movement, is it safer for the brake to hold absolutely firm or to start slipping before the line reaches its breaking point? Why? • Look at which options mention both a high‑capacity brake and a requirement to slip and ask: which combination best reduces the risk of a dangerous line parting?

✅ Before You Answer

• Identify which choices say the brake allows no slippage and consider the snap‑back hazard if a line parts at full strength. • Check which option ties the brake capacity to a load near but not beyond the line’s breaking strength and then specifies slipping at a lower tension. • Eliminate any option that suggests either an obviously under‑sized brake or one that must never slip even if the line is about to part.
