The helmsman should attempt to maintain a course within how many degrees?

The helmsman should strive to maintain a course within 10 degrees to ensure safe navigation and maneuverability of the vessel. This level of precision helps the boat maintain an effective heading, which is crucial for avoiding hazards, ensuring efficient travel, and complying with navigational rules. A course deviation of more than 10 degrees may lead to losing situational awareness, particularly in busy or confined waterways where other vessels and obstacles need to be monitored closely.

By adhering to a 10-degree margin, the helmsman can make necessary adjustments to the course with more accuracy and respond promptly to changes in conditions or navigational requirements. It promotes better control of the vessel, enhancing safety for the crew and passengers, as well as other boats in the vicinity.
