Which statement is TRUE to back a right-handed, single-screw vessel in a straight line?

Question 1 of 27070

Which statement is TRUE to back a right-handed, single-screw vessel in a straight line?

🔍 Key Concepts

• Behavior of a right-handed propeller when going astern • Effect of propeller wash over the rudder when backing vs going ahead • How large rudder angles affect stern motion and vessel speed when backing

💭 Think About

• First, picture which way the stern tends to swing when a right-handed propeller goes astern. How does that natural swing affect your need for rudder? • Compare the flow of water over the rudder when moving ahead versus astern. How effective is the rudder when backing? • What happens to the vessel’s speed and control if you put on a lot of rudder angle while backing? Does it help you track straight, or does it act like a brake and increase sideways motion?

✅ Before You Answer

• Be clear on what right-handed means: which way does the propeller turn when going ahead, and how does that change when going astern? • Think about how much water flow is actually going over the rudder when backing and how that limits rudder effectiveness. • Consider whether extreme rudder angles are helpful or harmful for keeping a straight line when backing a single-screw vessel.
