To navigate to a sighted object using a compass, which action is required?

When navigating to a sighted object using a compass, the critical action is to point the compass toward the object and then rotate the bezel until the witness marks align. This method ensures that you are setting a specific bearing toward the target while taking into account the magnetic declination and your current heading.

Aligning the witness marks properly allows you to determine the correct direction to travel toward the object while also ensuring accuracy in your navigation. This is essential in underwater navigation, where visual references may shift frequently, and maintaining a proper heading is crucial for reaching your destination effectively.

Other methods may lead to confusion or misdirection. For example, pointing the compass toward the object and merely following magnetic north does not account for the actual direction you need to take. Just rotating the compass dome to align with the horizon is not sufficient for navigating to a specific point. Similarly, aligning the lubber line with the object and adjusting for wind direction may not be applicable underwater, where wind does not have the same effect as on the surface.
