🔍 Key Concepts

• Effect of twin-screw operation on heading when one engine changes speed or stops • Relationship between center of thrust and centerline of the vessel • Difference between ahead and astern propulsion effects on turning tendency

💭 Think About

• Visualize the two propellers pushing the ship ahead: what happens to the side force when one of those pushes suddenly disappears? • Think about where the remaining thrust is located relative to the ship’s centerline—on which side—and which way that side force would tend to swing the bow. • Compare this with what happens when you use only one engine ahead on a twin-screw vessel during docking—what direction does the bow tend to swing?

✅ Before You Answer

• Identify which screw (port or starboard) is still turning ahead and providing thrust. • Determine on which side of the centerline that remaining thrust now acts alone. • Confirm whether you are considering ahead propulsion only (no astern or rudder influence) when deciding which way the bow will swing.
