Jake,
I think seamanlike is NOT a definition in this cycle...
So it is just the ordinary understanding of the word.

Probably better term for me to use would be GE could sail behind Artimis. So, Bow down, rudders stalled would not be my understanding of sailing...

The actions of the crew would be unseamanlike in having to avoid Artemis.

I have NO citation for this one that I can remember though. I will check Perry when I get a chance.

At any rate... the standard to meet is room and opportunity ... I could see the PC judging that Artemis was too close.
irrespective of the words used to describe the near miss.
