>What flag are they flying on the stern?
That's Bermuda, one of a dozen "bad guy" flags you see on superyachts bought with embezzled funds.
The open registries will register anyone and most of them DGaF about money laundering laws or nominee director shell companies and they usually do those too so it's a good place to put a yacht you want to protect from sanctions and conceal from journalists, interpol etc.
Not all the flags on picrel are equally bad and there's a few left off but it's a good start.
