🔍 Key Concepts

• hydrodynamic interaction between a moving hull and a nearby bank • difference between cushion effect (pressure increase) and suction effect (pressure decrease) • how water pressure builds up at the bow near a bank vs what happens at the stern

💭 Think About

• Which term best describes water being forced and piled up between the vessel’s bow and the bank: does that sound more like increased pressure or drawing water away? • Think about which side of the vessel (bank side vs open-water side) experiences a higher water level and pressure in this situation. • Which option names the effect that tends to push the bow away from the bank when water is compressed between them?

✅ Before You Answer

• Verify which term describes a high‑pressure cushion of water between the hull and the bank. • Distinguish clearly between cushion (pushing away) and suction (pulling toward). • Eliminate any term that normally refers to the stern or overall wake pattern rather than the bow‑to‑bank interaction.
