Question 1 of 27070

When a line is subject to wear where it passes through a mooring chock, it should be __________.

🔍 Key Concepts

• Chafing – damage that occurs when a line rubs repeatedly over a surface such as a chock or fairlead • The purpose of protective coverings on lines in way of chocks, bitts, or fairleads • Traditional line treatments like worming, parcelling, and serving vs. localized abrasion protection

💭 Think About

• Which option describes something specifically used to protect a line from rubbing against a hard surface, rather than to strengthen or seal the line along its whole length? • Think about what you would place exactly at the contact point in the chock to take the wear instead of the line itself. • Which of these methods is most commonly mentioned in seamanship texts for preventing abrasion of mooring lines where they pass through chocks or over rails?

✅ Before You Answer

• Identify which choice is designed primarily for abrasion (chafe) protection rather than weatherproofing or general line preservation. • Consider what is actually used on deck in real mooring situations at chocks, bitts, and fairleads on modern vessels. • Eliminate any option that mainly relates to seizing, sealing, or fairing a line, not protecting it from rubbing at one small area.
