Yacht Information needed

With what's happening to the economy, and especially in Las Vegas, there will be a lot of scams going around (job offers, schools that promise a lucrative career,etc.). Anyone thinking of looking for work in the yachting industry should understand that, unless you have impeccable creds and one heck of a reputation, jobs just don't fall from the sky. There are a lot of seasoned professionals in every aspect of the boating and yachting industries selling shoes and such these days, and pounding the docks in their spare time. In the best of times this is a hard business to get started in. And because of how far flung jobs are, you can easily get somewhere and find yourself at the mercy of someone who has none. Females should be especially cautious.

My 22 yr old son, a recent college grad, was working at a restaraunt this evening and was approached by his diners about a captain's job on a Lagoon51 Catamaran for about 200k per year. My son has zero experience. I told him this "opportunity" was very suspicious and sounded like a scam. Has anyone heard about this type of situation (scam)?

Heard of the situation specifically or generally? As in a scam, yes. Happens all the time.
Can you imagine chatting with someone over ordering their meal and they want to hire you as a captain for a 50' condomaran for yacht captain wages and you are not a captain? Absurd, scan or not. Run away young Luke Skywalker.
What did your son tell them?

Committed to nothing but he did give them his #. Mistake I know but he is 22.

Maybe, maybe not. Risk/Reward. Diners asking a nice young man that provided great service to captain a Lagoon 51 seems possible. If, big if, they have such a boat, they should know one must be licensed by the USCG to be a captain.
Let us know if they call him.

The USCG only has jurisdiction over US Flag Vessels, if the vessel foreign flag and is private and the insurance will cover someone or the owner covers his own insurance then someone without a ticket can be the operator

Even in U.S. no captain's license is required for that boat if not for hire, but that offer is an absolute scam, total b.s. or sex trafficking. Imagine being 30 miles from shore and being given an ultimatum or drugged.

RE getting a job on a yacht: A somewhat dim, clueless but nice young man I knew was driving a taxi in Newport RI. He was asked by a passenger if he knew how to cook and he said yes, even though that was not really the case. He got an immediate offer to be the cook on an elderly 85 foot charter yacht in Newport. I'm not sure how long the gig lasted but I doubt more than a week or two.

Btw, if a captain of a 51' gets paid $200K a year these days I'm coming out of retirement. 

Jump in, the water is warm.

Those strange owners are out there. I once was hired as Captain for a delivery that had the owner, his girlfriend, his dog, his Gulfstream4 pilot, and the waiter from a restaurant he hired during dinner two days before the voyage as a mate. Very strange trip. The pilot could stand a watch, at least. The owner was quite wealthy, as his father had invented the shopping cart, and he himself invented the airport luggage cart, so he bought a yacht to see if he would like yachting. He didn't.
