Just as an aside, the USA’s coastal limit used to be 3 miles. I believe POTUS Reagan increased it to 10 miles during his presidency. But in the day when corporations wined and dined customers on big Yachts, 3 miles out put the good time fun & games into international waters and beyond “legal issues” for those involved… (what happens at sea stays at sea…as a lot of politicians were entertained/lobbied in this way too)
So…you’d want a Yacht equipped for fresh, brackish, or salt water operation.
Some here may remember a late 50’s TV Show…“Mr. Lucky” who operated a Large Yacht casino/restaurant in the heydays of this kind of “soldier of fortune” stuff
