🔍 Key Concepts

• Effect of a stalled engine on a twin-screw vessel’s heading • How thrust from port and starboard propellers affects turning tendency when rudder is amidships • Using rudder to counteract asymmetric thrust and maintain a straight course

💭 Think About

• If only the port (portside) engine is driving ahead and the starboard engine has stalled, which way will the vessel naturally tend to swing with the rudder amidships? • To keep the ship on the original straight course, should your rudder input oppose or assist that natural swing? • How does applying left rudder versus right rudder change the water flow over the rudder when only one engine is powering?

✅ Before You Answer

• First decide which way the bow will tend to turn with only the port engine ahead and rudder amidships • Confirm that the rudder you choose will counteract the yaw caused by asymmetric thrust, not increase it • Eliminate any option that does nothing to correct the turning moment created by losing thrust on one side
