Some of these guys have been doing this as long as I've been around, so they must have their reasons. I doubt they're adjusting just because someone else is on the boat, because it's all happening way too fast not to be their normal practice.

Their banter is typically shorter as well, such as "Starboard, right" and "port, give" (leaving out extra words like "boat," "of way," etc.). They rotate around at some events so that the same two people aren't together all day, and the banter is remarkably the same.
