🔍 Key Concepts

• Bitts, timberheads, and cavels – what they are used for on a dock or vessel • Typical fittings designed specifically for securing mooring lines • Which fittings are primarily for other purposes (e.g., piping, systems) rather than for tying lines

💭 Think About

• For each choice, picture it on a pier or vessel: is it shaped and placed so a line can be turned up on it safely? • Ask yourself which of these items is normally part of the ship’s or pier’s piping or systems, not deck mooring hardware • Think about what happens if you put a heavy mooring load on something that was not designed to take that kind of strain

✅ Before You Answer

• Confirm which items (timber head, button, caval) are standard mooring or belaying fittings • Identify if any option is actually associated with pipes or fluid systems rather than line handling • Verify which fitting might fail or be unsafe if used to secure a heavy mooring line
