Roller chocks as fairlead components are used to do what?

• A. Allowing rolling motion to reduce friction
• B. Increasing friction for grip
• C. Controlling ship speed
• D. Blocking the line completely

Answer: (A)

Roller chocks in fairleads let the mooring line roll as the ship moves, so the line slides smoothly instead of rubbing on a fixed edge. This rolling action reduces friction, lowers wear and heat, and makes paying out or taking in lines safer and easier for crew. Increasing friction for grip or blocking the line would hinder movement and create hazards, and using fairleads to control ship speed isn’t their function. So the best use is to allow rolling motion to reduce friction.
