Im sure there is a geographic line of Demarcation as well. I just never thought too much about it. Lets see if we cant find out.
As far as fish and game regs go the same principle applies to port of Berth. Whatever state you leave and return to determines state catch quotas and size limits even if caught in New Jersey waters from Staten Island. In other words if you catch 2 striped bass legal in New jersey waters and your port of berth was New York your subject to New York Regs which currently is one per day. and vice a versa if your berth is New Jersey You can take two from new York waters but you have to return to New Jersey.
How inappropriate to call this planet Earth when it is quite clearly Ocean.
