When a vessel with a single right-hand propeller backs to port which statement is TRUE?

🔍 Key Concepts

• Propeller side force (walk) on a single right-hand propeller when going astern • Difference between what happens to the stern versus the bow when backing • Meaning of "moves bodily" (straight sideways) versus swinging (change in heading)

💭 Think About

• When a right-hand propeller turns astern, which way does the stern tend to move due to propeller walk? From that, which way must the bow appear to swing? • If the stern is being pushed sideways by the propeller, will the vessel keep the same heading, or will the bow change direction? • Look at each answer choice: which ones describe a sideways slide with no change in heading, and which ones describe the bow changing direction?

✅ Before You Answer

• Identify which direction a right-hand propeller rotates when in ahead and in astern, and how that affects sideways force on the stern • Confirm whether the effect described involves the stern moving sideways or the bow swinging (change in heading) • Make sure the choice you pick correctly matches both the direction and whether the vessel is sliding or pivoting
