After graduation a kid I knew in school took off with his father to cruise down the FL gulf coast and out to the islands. They picked up a couple of women in Appalachicola FL (FL panhandle), headed out, and were never heard from again. No debris, nothing was ever found.
The cops were pretty sure the women were working with drug smugglers to hijack boats. This was early 70s so no satellite tracking, GPS, etc.
Piracy is still a ‘thing’.................
