🔍 Key Concepts

• bank effect on a ship near a river bank • interaction between pressure (cushion) at the bow and suction at the stern • how the ship’s heading changes when water flow is restricted on one side

💭 Think About

• Picture a ship moving close along one bank: what happens to water flow between the ship’s hull and the bank compared to the open side? • If water flow speeds up on one side, what happens to pressure there, and how will that affect the bow and stern? • Based on that interaction, does the vessel naturally move closer to the bank or try to turn away from it?

✅ Before You Answer

• Identify which choice describes a change in heading (sheering/turning) rather than just speed or position. • Ask yourself if the riverbank effect makes the vessel’s stern get sucked toward the bank or pushed away from it. • Confirm which option best matches the classic description of bank suction and cushion on a ship’s maneuvering behavior.
