🔍 Key Concepts

• Shallow water effects (squat) on a ship’s maneuverability and speed • How water flow around the hull and rudder changes when under-keel clearance is reduced • Relationship between rudder effectiveness and water flow (speed and pressure)

💭 Think About

• When a vessel goes from deep to shallow water at the same throttle, what typically happens to its speed through the water? Faster, slower, or unchanged? Why? • How does reduced under-keel clearance affect the flow of water to the propeller and then over the rudder blades? What does that do to steering response? • Think about whether shallow water makes a ship more ‘free’ to move or more ‘restricted’ by the water around its hull.

✅ Before You Answer

• Verify what the term squat means and whether it makes the vessel sit higher or deeper in the water at speed. • Consider whether rudder effectiveness improves or degrades when the flow of water past the rudder is disturbed or reduced. • Check if shallow water normally causes a ship to gain speed without extra power, or if it usually causes extra resistance instead.
