🔍 Key Concepts

• Bank cushion and bank suction effects when a vessel moves near a steep bank • How water flow and pressure change around the bow and stern close to a bank • Typical handling tendency of a ship’s bow and stern when close to one side of a narrow channel

💭 Think About

• Think about what happens to water pressure at the bow when it gets close to a steep bank—does it push the bow toward or away from the bank? • Consider the stern: as water rushes between the stern and the bank, does it tend to pull the stern toward or push it away from the bank? • Ask yourself which of the listed motions best matches this combined bow-and-stern behavior along a steep bank.

✅ Before You Answer

• Be clear on the difference between bow pushed away and stern pulled toward the bank • Check which option matches a vessel’s tendency due to hydrodynamic forces, not because of the helmsman’s intentions • Eliminate any answer that describes something that would happen only if the engine power changed, rather than from the bank effect itself
