Q

Which vessel, if navigating independently in ice, is more likely to become beset due to inadequate horsepower?

🔍 Key Concepts

• Power-to-length (or power-to-displacement) ratio and how it affects a vessel’s ability to work through ice • Effect of length and hull form on resistance when moving through ice • Which vessels are more prone to becoming beset in ice when underpowered for their size

💭 Think About

• Compare each vessel’s horsepower to its length and type; which has the least horsepower relative to size? • Think about which hull type (whaleback, cement carrier, shallow draft tanker, bulk ore carrier) is likely to be heaviest or offer more resistance in ice for the horsepower given. • Ask yourself: if two ships have similar horsepower but one is much larger, which one is more likely to get stuck when pushing through ice?

✅ Before You Answer

• Calculate or roughly estimate a horsepower-per-foot value for each choice. • Consider which vessel is likely to have the greatest displacement or mass for its horsepower. • Verify which choice combines large size with relatively low horsepower, making it most vulnerable to becoming beset in ice.
