This happens frequently in his area!!
Busy waterway with commercial ships, naval vessels, and very large commercial tankers, freighters and much smaller sailing vessels. Back in the day our RN minesweeper picked survivors out of the water when a sailboat crossed the path of a tanker running into the Fawley refinery, in this same area.
As stated in other threads, always get out of the way of big ships, no matter who is "stand-on" vessel. They may not see you, probably are unable to do anything about you, and may care less!!
