Have a care when assuming that
most Superyacht ops are private.
They aren't. Most superyachts are chartered out when the owner is not using it, and then it becomes Public Transport. On most big yachts crew have secondary duties too, you'll almost certainly be expected to be a deck hand, watch keeper and engineer too. They don't tend to have specialist pilots sitting on their fannys doing nothing for 9 1/2 days out of 10. The biggest hazard for all superyacht crews is the boredom from long periods of inactivity. Thee things can spend months at a time tied up going nowhere...
