You had me until you started quoting the numbers of the qualified and non-qualified officers during your particular tour. I’d be MIGHTY surprised to see THAT level of manning on any surface combatant much less one in the C7F AOR. That said, even with less manning, the arrivals and departures are still limited.
I pilot SSBNs routinely and am quite familiar with the how they cycle the JO’s through the process. It’s unfortunate in that any lessons that might be learned during any given evolution are lost by the time they get cycled back around for their next opportunity. And not for nothing, as important as those sea details may be. It won’t make them better watchstanders at sea. I, for one am a big fan of how at least the Dutch and Royal Navies have their Navigators at the Conn for arrivals and departures. THAT process doesn’t solve the problem of improving watchstanding skills at sea, though.
