🔍 Key Concepts

• Behavior of an ice-reinforced bow when meeting pack ice • Effect of vessel trim (bow up vs bow down) on striking ice • Relative conditions of windward vs leeward ice edges and coastal leads

💭 Think About

• Think about how an ice-strengthened hull is designed to interact with ice: does the bow normally cut through, or ride up and break ice by weight? • Consider whether you want to seek out the weakest-looking ice (like rotten ice) near the edge, or a more uniform area away from pressure ridges and breaking zones. • Ask yourself what windward and leeward sides do to the motion and concentration of ice around the edge of a pack.

✅ Before You Answer

• Verify how even keel vs down by the bow affects how the ship contacts ice with its strengthened areas. • Consider whether windward pack edges are usually tighter and under pressure, or looser and more open. • Check whether coastal leads created by offshore winds are always safe, or can they close and trap a vessel if conditions change?
