Q

You are on a single-screw vessel with a right-handed propeller. The vessel is going full speed astern with full right rudder. The bow will swing __________.

🔍 Key Concepts

• Effect of a right-handed propeller when going astern (transverse thrust or "walk") • What the rudder can and cannot do when the ship is moving stern-first • Difference between initial swing and eventual swing of the bow at full speed astern

💭 Think About

• First, picture which way the stern will walk when a right-handed propeller is put full astern. If the stern moves one way, which way must the bow appear to swing? • At full speed astern, is the rudder effective in turning the bow like it is when going ahead, or is its effect reduced? How does that change what really controls the swing? • Think about whether the bow’s movement will be steady in one direction or if there would be a change in rate or direction as the ship settles into going astern.

✅ Before You Answer

• Be sure you know which way a right-handed propeller turns when going ahead vs. astern • Confirm which end of the ship (stern vs. bow) the transverse thrust acts on when backing • Check whether the answer choice describes a consistent swing or a swing that changes direction or speed, and see which best matches backing with a right-handed screw and full right rudder
