Q

Which describes how flanking rudders effect a vessel's heading when going astern?

🔍 Key Concepts

• How flanking rudders are positioned relative to the propellers on a river towboat or tug • The difference between water flow caused by the propeller wash versus water flow caused by the vessel’s own movement through the water • What part of the hull structure (like deadwood or skeg) is affected when engines are put astern

💭 Think About

• When going astern, what is the strongest and most immediate source of water flow that can act on the rudders? • Do flanking rudders depend more on the boat’s speed through the water, or on the water being pushed/pulled by the propeller? Why? • Which option best matches the idea that flanking rudders are designed to use propeller flow to steer even at very low vessel speed?

✅ Before You Answer

• Identify which choices talk about propeller-driven flow versus hull movement through the water • Ask yourself which effect would still work if the vessel is almost dead in the water but the engines are engaged astern • Eliminate any choice that doesn’t clearly involve water flow being directed onto the rudder surfaces to create a turning moment
