Sorry, but if this kind of situation happens to you then you should not be out on the sea.

If you think that some random rock in middle of open sea, which was probably charted in 1953, is measured with that kind of accuracy that you can pass it by 5 meters then you have more problems than GPS accuracy.

And nobody said buoys are obsolete. Article is about lighthouses (https://en.wikipedia.org/wiki/Lighthouse)
