Rudder settings: what are the degrees for Standard, Full, and Hard?

• A. Standard - 30; Full - 40; Hard - 60
• B. Standard - 15; Full - 25; Hard - 45
• C. Standard - 10; Full - 20; Hard - 30
• D. Standard - 20; Full - 30; Hard - 35

Answer: (D)

Rudder angles are a measure of how aggressively you steer, and the practice uses a clear progression from moderate to maximum authority. The standard setting is about 20 degrees, giving a gentle but noticeable change in course with manageable yaw and minimal impact on speed. Increasing to full about 30 degrees doubles the steering input, producing a sharper turn and a higher yaw rate, which you’d use for larger course changes or countering drift. Pushing to hard around 35 degrees provides the maximum practical rudder effect before control becomes unstable or the hull flow disrupts the rudder’s effectiveness; it’s the most aggressive input you’d typically rely on in routine handling.

These values reflect a common, safe scale used in training, balancing turning performance with control and safety. Other sets with markedly higher numbers (like 40 or 45 degrees) or with much smaller steps don’t align with how ships respond in practice, making the 20°, 30°, 35° progression the correct and useful reference.
