How many degrees can the rudder angle indicator display on each side?

The rudder angle indicator is designed to provide a clear and effective measurement of the rudder's position, which is essential for navigation and maneuvering of a vessel. The correct range of 0 to 35 degrees on each side allows for sufficient rudder angle display that accommodates typical operational needs. This range is critical, as it covers a significant part of the rudder's effective operational angle without being so large that it becomes unnecessary for standard navigation practices.

Understanding the limitations of the rudder angle indicator is important; if it were designed to display a significantly higher degree on each side, it could lead to misinterpretation during navigational maneuvers. A range of 35 degrees provides a balance between accuracy and practical application, ensuring that users can effectively read the rudder position without overcomplicating the readings. Hence, the answer accurately reflects practical rudder operations.
