🔍 Key Concepts

• Effect of a single working propeller when a twin-screw vessel is moving astern • Transverse thrust (sideways push) of a right-hand vs left-hand propeller when going astern • Difference between what the stern does and how that motion makes the bow appear to move

💭 Think About

• First decide: when only the port screw is turning astern and the rudders are amidships, which way will the STERN tend to move due to transverse thrust? • Once the stern moves that way, which direction must the BOW appear to move around the vessel’s pivot point? • Ask yourself whether the bow can really "remain stationary" if thrust is being applied on only one side while moving astern.

✅ Before You Answer

• Identify which screw (port or starboard) is still turning and in which direction (ahead or astern) • Recall the usual transverse thrust directions for right-hand and left-hand propellers when going astern • Visualize the vessel pivoting: if the stern is pulled one way, the bow must swing the opposite way
