VHF radio traffic can be enormously entertaining.
Coming through the narrow channels south of Norfolk I heard a tug captain pushing a barge do a wonderful job of being insistent but polite to a sailboat that refused to leave the dead center of the channel, leaving no room for the barge heading in the opposite direction. The irrational sailor was a real piece of work while the tug captain tried to explain the consequences.
On another occasion a large fast cruiser was abusing a displacement speed vessel for not going faster than displacement speed, causing the large fast vessel to go slower than he wanted for about 20 min until there was a wide enough spot to make a pass. The displacement guy was explaining displacement speed concepts, but it might as well have been in latin because the speed guy could not accept that it wasn't just a case of pressing the throttle.
You can tell when some captain has plugged in the "Bob Track" for that area, because those guys will not deviate. Self defense involves staying out of their way.
