🔍 Key Concepts

• Towing vessel deck structures commonly found near the stern • How a heavy steel arch is used to guide or protect towing gear • Differences between structural framing members and gear-protection fittings

💭 Think About

• Which of these terms would most likely describe something shaped like a curved arch over the after deck that towing wires or lines might pass under? • Do any of the choices sound more like interior framing (inside the hull or deck), rather than external gear on a towboat? • Think about what needs protection on a towing vessel’s after deck and which term is associated with that function.

✅ Before You Answer

• Identify which choice is known as a deck framing member, not usually an exposed arch over the after deck. • Consider which term is specifically associated with towing arrangements on pushboats and towboats. • Ask whether any option describes a protective structure for tow wires or lines rather than just a general reinforcement or wear surface.
