What is the maximum degree allowed for rudder movement?

The maximum degree of rudder movement is important to ensure safe navigation and handling of the vessel. A maximum rudder angle of 35 degrees is generally accepted in the maritime industry as it allows for effective maneuverability while reducing the risk of excessive stress on the rudder system. When the rudder is angled too far, it can lead to issues such as cavitation, loss of control, or even structural failure of the rudder itself.

This limit is designed based on safety studies and practical experience, ensuring that vessels can respond appropriately in various conditions without compromising structural integrity or safety. Knowing this maximum angle is critical for crew members responsible for steering and maneuvering, as it affects turning performance and overall handling characteristics of the vessel.

In contrast, the other choices provided reflect angles that exceed the established safe limit, which is why they are not considered correct in this context. A proper understanding of rudder movement is essential for effective vessel operation and safety.
