Yes, modern day piracy is very real. Many of the modern day pirates use things like AK-47’s, super fast dinghy’s, torture techniques, etc.
They still kidnap n’ ransom Captains. The Caribbean is flooded with pirates right now, especially around Grenada and Antigua.
So be safe when traveling out there, it’s no joke. The more expensive your boat looks, the more of a target you are for these pirate scum.
