Your ship is dead in the water with the rudder amidships. As the right-handed screw starts to turn ahead, which way will the bow tend to go?

🔍 Key Concepts

• Right-handed screw (propeller) acting ahead • Effect of transverse thrust/propeller walk when a vessel is dead in the water • How the pivot point shifts when going from stopped to moving ahead

💭 Think About

• If the propeller is right-handed and just starting ahead, which way does the stern try to move due to transverse thrust, and therefore which way does the bow swing? • Picture the ship from above: looking from astern to ahead, which way do the blades move through the water on the downward (starboard) side versus the upward (port) side? • When the ship is initially dead in the water, is the bow or stern more affected by propeller forces, and what does that do to the bow’s direction?

✅ Before You Answer

• Be clear on what right-handed means: direction of rotation when viewed from astern in ahead gear • Confirm whether propeller walk initially moves the stern sideways more than the bow when starting from dead in the water • Eliminate answers that ignore the transverse thrust effect and assume only forward motion (i.e., "straight ahead").
