🔍 Key Concepts

• Twin-screw vessel handling with only one engine operating • Transverse thrust and the tendency of a single operating screw to yaw the vessel • How rudder angle counters asymmetrical thrust when one engine is lost

💭 Think About

• Visualize which way the bow will tend to swing when only the starboard engine is driving ahead and the port engine is dead • Think about which way you must push water with the rudder to create a correcting force opposite to that swing • Consider what the term 'surging' an engine does to control versus just setting a steady correction

✅ Before You Answer

• Determine which direction the vessel will naturally yaw with only the starboard screw turning ahead • Identify which rudder direction will create a counteracting force to keep the vessel on a straight course • Verify whether a twin-screw vessel still needs rudder compensation when one engine is lost (do not assume they cancel out)
