🔍 Key Concepts

• Overrunning / overriding tow: When the tow gains on or climbs up toward the stern of the towing vessel • Stability and capsizing risk of the towing vessel when forces come from astern and off-center • Difference between mechanical damage (e.g., fouled screw) and sudden loss of stability

💭 Think About

• When a tow starts to override the tug, where is the main force being applied to the tug, and how does that affect its stability? • Which of the listed outcomes can happen very suddenly and leave almost no time for corrective action? • Which option directly relates to the tug being pulled sideways or astern in a way that could roll it over?

✅ Before You Answer

• Identify which choice describes a sudden stability failure of the towing vessel, not just damage or loss of control. • Ask: Which event is especially feared by tug operators when a tow is on short scope and starts to overrun them? • Distinguish between gradual problems (like fouling or loss of steering) and a catastrophic, rapid event.
