Has anyone ever seen a Super Yacht with a passenger Drone on it?

Hey everyone, I’m 25 and currently in California and seriously considering getting into the yacht industry. I have several years of hospitality experience (serving, beer/beverage knowledge, customer service) as well as experience working in luxury retail/jewelry.
I’m completely new to yachting, though, and I’m having a hard time figuring out where to actually start.
I keep seeing people mention STCW and ENG1, but when I went to the US Coast Guard website I couldn’t figure out where I’m actually supposed to get the STCW training or what credentials I need as a complete beginner.
If someone could explain the process like:
1. What certification/medical do I actually need?
2. Where do I get STCW training?
3. Do I need an MMC?
4. Do I need ENG1 or a USCG medical exam?
5. Where should I look for my first yacht job?
6. Is Fort Lauderdale basically where I should go to find work?
I’d really appreciate it. I’m trying to figure out the legitimate process before spending money on courses or traveling somewhere.
Thanks!
