I tend to stay on the edges of the pack anyway, however, there may be times when you have to turn to avoid someone else and the only viable path is behind another boat. When that happens, I tend to give them plenty of space. At least 100 yards, if not more. They may have to slow down to fight a fish or whatever, so I don't want to be in a situation where I am "breathing down their necks".

Funny story last fall when I was out trolling off of Luna Pier. I was trolling down-wind and trying to stay on the my previous path that was very productive for us. There was only one other boat in the area and he was a few hundred yards in front of us and appeared to be trolling against the wind, "headed" right in our direction. I looked up one time and it appeared that he would cross in front of us and end up on our starboard side, so I turned a bit to port to give extra clearance. A few moments later, I looked up again and it now appeared that he would cross us and end up on our port side, so I turned back starboard to make sure we cleared him. The 3rd time I looked up, he had "changed paths again", so I steered back towards our port side. I said to my buddy "what's up with this guy, he can't make up his mind on which direction he wants to go and he keeps messing me up". As we got a bit closer, I could see there was an anchor rope attached to his bow and he was simply swaying back and forth with the wind. Doh! That explains it. Sorry buddy, my bad!
