You are landing a single-screw vessel, with a right-hand propeller, starboard side to the dock. When you have approached the berth and back the engine, how would you expect the vessel to respond?
• Transverse thrust (propeller walk) on a right-hand single screw in reverse • How backing a single-screw vessel affects stern movement and therefore bow direction • Docking starboard side to: which way must the stern move to bring the bow closer or farther from the dock
• When a right-hand propeller is put astern, which way does the stern tend to move due to propeller walk? From that stern motion, which way must the bow swing? • If your vessel is already close to a starboard-side-to berth and you back the engine, would the natural prop walk tend to help you lie alongside or push you off? • Eliminate any option that ignores the typical sideways force of the propeller in reverse on a right-hand single-screw vessel.
• Be very clear about right-hand vs. left-hand propeller effects in reverse • Visualize the vessel from astern, looking forward: which way does the stern move when backing with a right-hand prop? • Confirm whether the described motion in each option matches the expected stern movement and resulting bow swing for this propeller and engine setting.
