Bearing information shows where another vessel is relative to your own, which is essential for collision avoidance. Knowing the target’s relative bearing lets you track its motion as you close or pass, and, together with range, you can estimate how quickly you’re approaching and whether the target’s path will intersect yours. This enables timely decisions about course or speed changes to maintain safe separation, and it supports calculations like time to the closest point of approach. The other options miss this core purpose: bearing isn’t about your own heading measurement to the target, it doesn’t indicate weather, and it doesn’t replace the need for a lookout on board.
