Turns out that the boundaries of the State, at least on the east coast, are defined by the easternmost edge of the Gulf Stream. Yep. Those of you with any marine background will probably know that the Stream, well, meanders, depending on the time of year, direction and strength of the wind, etc.
As a result, jurisdiction over a shipboard doctor in this wrongful death case depended on where exactly the ship was at the time and where exactly the Gulf Stream was on that day.
Strange but true.
