What does the lubber's line indicate when aligned correctly?

The lubber's line is the forward reference on a ship's compass. It marks the direction the bow is pointing. When that line is aligned with the vessel’s centerline, the compass reading corresponds to the ship’s actual heading. This alignment is essential for reading the correct course; it isn’t about speed, north direction, or depth, which are determined by other instruments.
