I suppose it might teach people how to program waypoints into an autopilot, so that they didn't try to ram the buoys or take shortcuts over land.
We had a real-life example of where that would have been useful a few years back.
A medium sized cargo vessel tried to sail up Selsey High Street in order to reach the top of Southampton Water, having come down past the Dover Straights.
Fortunately, the shingle banks stopped the vessel, rather than any of the rocks. It was floated off at a Spring high tide about a week later, the weather having been kind.
The sniggering local fishermen were perhaps not so kind.
