🔍 Key Concepts
• Function of chafing gear on lines, hawsers, or mooring ropes
• Difference between wear from rubbing and corrosion (rust/chemical deterioration)
• Typical situations where you would install chafing gear on board (e.g., where a line passes over a sharp edge or through a chock)
💭 Think About
• When and where do mariners actually put chafing gear on a vessel’s lines? Visualize a moored vessel in a seaway.
• Is chafing gear meant to deal with mechanical rubbing or a chemical/electrochemical process? How does that relate to the options mentioning corrosion?
• Which option best matches something you’ve physically seen or could imagine wrapped around a mooring line or hawser?
✅ Before You Answer
• Identify which choices refer to rubbing/wear versus corrosion or body protection.
• Ask yourself: which option describes protection for lines and rigging where they pass over surfaces or through fairleads/chocks?
• Eliminate any options that describe functions unrelated to mechanical abrasion between two surfaces.
