After a maneuver, how long until the target's vector catches up?

After a maneuver, the target’s velocity vector doesn’t jump to the new course instantly because vessels can’t change speed and direction instantaneously. The target needs time to complete the turn and settle onto a new speed, and the radar’s tracking/plotting has to update to reflect that change. The result is a lag where the plotted vector gradually shifts toward the target’s actual path. In typical maritime maneuvering, this convergence takes on the order of several minutes, not immediate, seconds, or hours.
