🔍 Key Concepts

• Right-handed propeller and which way the stern tends to move in reverse (transverse thrust) • How a controllable-pitch propeller (CPP) changes thrust direction while the shaft keeps turning the same way • What happens to rudder effectiveness when engine power is reduced or thrust goes through zero while you still have headway

💭 Think About

• Think about how the rudder gets its force: does it depend more on water flow from the propeller, or on the ship’s speed through the water? • When you go from maximum ahead pitch to reverse pitch, is there a period where propeller thrust is low or zero? What does that do to steering? • For a right-handed propeller, what is the usual direction of stern movement in reverse, and does that effect appear immediately while you still have headway?

✅ Before You Answer

• Be clear about the difference between propeller rotation direction and pitch direction on a CPP • Consider whether transverse thrust will dominate while you still have significant ahead motion through the water • Verify whether continuous, effective rudder control is realistic while thrust passes through zero and then astern
