Which factor has the GREATEST influence on the squat of a vessel in shallow water?

🔍 Key Concepts

• Squat: how water flow under the hull changes with speed and depth • Difference between speed/course over the ground vs through the water • Effect of water depth and flow past the hull on pressure and trim

💭 Think About

• Ask yourself: What actually causes squat – is it about the ship’s motion relative to the seabed or relative to the surrounding water? • Which of the four choices directly changes the flow of water past the hull and thus the pressure under the keel? • How would squat change if you had a strong current but kept the engine RPM the same?

✅ Before You Answer

• Identify which options involve over the ground versus through the water and recall which one reflects true hydrodynamic speed. • Recall that squat increases roughly with the square of the ship’s speed in the water, not its track over the seabed. • Verify which factor most directly controls flow velocity under the hull, rather than just the vessel’s heading or track.
