🔍 Key Concepts

• Hawser towing dynamics between tug and barge when speed is high • How a sudden change of heading affects the path of the tow compared to the tug • Which situations create the greatest risk of tug being struck or overrun by the tow

💭 Think About

• Picture the tug ahead, barge astern on a long hawser at speed. If the tug puts the rudder over to swing the barge, what path does the barge’s bow take relative to the tug? • Which of the listed dangers is most directly caused by the geometry and inertia of a long tow when you try to swing it quickly? • Ask yourself: which option depends mainly on towing arrangement and relative motion, and which ones depend on more special conditions (like liquid cargo or unusual sea state)?

✅ Before You Answer

• Identify which answer choice is most directly tied to relative motion and over‑taking risk between barge and tug during a sharp swing. • Check which options describe hazards that could happen even without a hawser swing (e.g., free surface effect, wakes) and which one is specific to this maneuver. • Visualize the barge’s arc as it swings—does it tend to move inside the turn toward the tug, outside, or under the towline—and which choice best matches that specific risk.
