What should be done after tuning the set for accurate navigation?

After tuning the set for accurate navigation, aligning the boat with the pointer is the appropriate action because it ensures that your vessel is headed in the correct direction as indicated by the navigation system. This step is crucial for effective navigation, as it allows the crew to follow the intended course and make timely adjustments based on real-time data.

Correctly aligning the boat helps ensure that all navigational instructions, such as waypoints or headings, are followed precisely, enabling a safer and more efficient journey. This alignment is an important practical application of the navigational data provided by the tuned equipment, bridging the gap between technical setup and real-world navigation.

While the other options might seem relevant, they do not address the immediate need of ensuring the vessel is set on the correct course after tuning the navigation equipment. Therefore, proper alignment with the navigational pointer is vital for direction and safety at sea.
