..... The captain, fist mate & second mate are all licensed. One of our captains comes from the ranks of the professional maritime trades
Again, I believe the best outcome will be to find this totally inadequate.
Getting your profession ticket on a merchant ship, for example, allows for zero experience sailing an 18th century replica. The deck hands should have specific experience as well, when going offshore.
Nonsensical psuedo training, non-inspected vessel stuff should end.
Let them sit at dockside or putter around the bay, but if you want to move them in open water, the crew should be locked and loaded for anything. They should have serious experience, in addition to their ticket. Not just supervised. No joy rides.
I don't really care if one wants to risk their life. This example shows, in my opinion, that one may be convinced to take a risk they have no way to measure themselves and accept the reputation of the skipper as their guidance.
