I truly believe that you have not heard anything resembling reality my good fellow…sorry to burst your balloon, but the uber-yacht market for masters, etc…is an extremely closed community where jobs on the top yachts are solid gold treasures never to be touched by any mere mortal mariner. If you’re willing to slum it on a 70-100’ yacht then I believe the market is much more open but think of it as the dues to pay to gain entre to the business where you’ll have to do a bunch of scrubbing, buffing and oil changing lube oil at modest pay without much time off. And no beautiful 20 something stewardesses either. If you’re hitched to a gal who is willing to go along with you and cook/clean/serve then you have a very good chance of finding something available out there.
