I've never heard that before. Out here, the only thing I can
think of would be that they're warning you off, but that doesn't
seem to be the right sound.

That was my thought at the time. However, on reflection, that wouldn't make
sense. Sound signals are common in the Solent (esp. 5 toots), and I've
never seen a ship get them wrong.
