🔍 Key Concepts

• Difference between ice-strengthened / reinforced and un-reinforced vessels • Meaning of ice concentration in tenths (how “packed” the ice is) • General safety guidance: higher ice concentration = higher risk for ships without ice reinforcement

💭 Think About

• Ask yourself: At what point does ice go from being mostly open water with scattered floes to becoming a nearly solid sheet? An un-reinforced hull should stay well below that. • Compare each choice to the idea of a “margin of safety” for a normal commercial vessel. Which range leaves plenty of room to maneuver between floes? • Think about the stress on a standard hull: would you want to be in more than half-covered ice, or mostly open water with some ice patches?

✅ Before You Answer

• Be clear on what “tenths” of ice concentration means (e.g., 10/10 = completely covered, 0/10 = no ice). • Remember that an un-reinforced vessel does NOT have extra hull strengthening for ice pressure. • Eliminate any choice that suggests operating in ice concentrations that are close to a solid or nearly solid ice cover.
