In fact @Lee_Shore I think this is related to what you said about the academy grads that go on tugs getting their boat handling skill quicker.
When I was mate I’d get sent out on the barge with a radio to assist with guiding the barge in. By contrast a junior deep-sea mate will often just be waiting for orders from the bridge. I’ve noticed this having spend a lot of time and effort getting the mates to change their habits in this regard.
