A tug is "in irons" when held in a fixed position by __________.

🔍 Key Concepts

• Tug and tow forces – what can balance a tug’s engine thrust so it makes no progress through the water or over the ground • Difference between being stopped by gear failure/grounding and being stopped by external forces like current • Normal meaning of “in irons” as a term for being held in place rather than simply losing power

💭 Think About

• Ask yourself: in which option is the tug still trying to move ahead under power, but something outside the tug is holding it in a fixed position? • Which options describe a specific towing condition or environment rather than just a mechanical problem or an accident? • If a tug loses power completely, is that usually described with a special towing term, or just as having an engine failure or being disabled?

✅ Before You Answer

• Check which choice involves a continuing opposing force that can exactly counter the tug’s thrust so it makes no headway. • Eliminate any choices that mainly describe damage, casualty, or gear failure, rather than a descriptive towing condition. • Make sure the situation you pick could leave the tug apparently motionless even though engines are working and the tug is under full power.
