🔍 Key Concepts

• Propeller side force (transverse thrust) on a single-screw, left-handed propeller • Effect of rudder when there is no water flow past it (vessel making no way) • Difference between what moves first: bow vs. stern when only propeller is working

💭 Think About

• Think about whether the rudder can create turning force if the vessel is stopped in the water with no flow past the rudder • On a left-handed propeller, when you first go ahead from a stop, which way does the stern tend to "walk"? How about when you go astern? • Does the rudder or the propeller side force dominate when there is no headway or sternway?

✅ Before You Answer

• Verify what left-handed propeller means (direction of rotation in ahead gear and its side effect on the stern) • Confirm whether rudder angle alone can move a stopped vessel without flow over the rudder • Decide whether the initial movement should be described as a kick of the bow or a kick of the stern, and to which side
