🔍 Key Concepts

• Heavy ice navigation and what it means for a ship to become beset • Typical methods a master might use to try to free a vessel from ice without outside assistance • Relative risk to rudder and propeller when maneuvering in ice (ahead vs. astern, stopped vs. slow turns)

💭 Think About

• Think about which options describe realistic, commonly recommended seamanship practices for a ship trapped in heavy ice. • For each choice, ask: does this sound like something that would actually HELP free the ship or PROTECT the vessel’s machinery, or does it sound risky or ineffective? • Focus on which statement describes a condition that is not necessarily true, or a practice that would generally NOT be recommended in heavy ice.

✅ Before You Answer

• For each choice, consider whether it is always true, usually true, or only sometimes/rarely true in practice. • Mentally picture the flow of ice around the rudder and propeller when going ahead versus backing and when the propeller is stopped versus turning slowly. • Ask which option describes a method that might actually increase the chance of damage or is not a reliable way of freeing a beset vessel.
