On our small crowded lakes, 100 feet is sometime generous. I don't like it, I don't do it to anyone, but unless they get right on top of me, there's not much I can do about it. It's just how it goes on an 800 acre lake with 30 boats fishing a tournament on it.
I feel like I get less of this than most guys, because most of the tournaments I fish in....I also run, and it's not wise to tick off the tournament director. But I also have to be on eggshells too, I can't be accused of "doing whatever I want" because I am the tournament director.
My general rule of thumb is...........if I want to fish an area and someone else is in it I:
#1 go to another area, I can catch fish anywhere on the lakes I fish.
#2....if #1 is not an option, I will see what way the other boat is going, and get behind them a respectable distance.
#3 If I get behind them, and they whip the boat around....it's a sign they are keen on keeping me out. So I leave.
#4 if I see a guy working shallow in an area I want to go, I ask permission to fish deep, staying off their stuff, or vise versa, if they are fishing deep, I ask to slip by shallow, and won't bump out to deep water until I am well away from them and the area they are fishing.
99.9% of the time this is how everyone behaves around here, we all get along, we all catch fish, and no fights or arguments break out.
I tend to conduct myself the same way fun fishing too, and most of the time it works out fine. The biggest problem I have, is when I am out on my lake fun fishing, and another tournament that I am not in is there. I try my hardest to stay out of the way. But have had other organizations anglers show ZERO respect for a local or recreational fisherman. That really gets under my skin, as I also do my best when in a tournament to respect the space of the non-tournament anglers on the water as well.
Other fisherman acting like jerks on the water is my biggest pet peeve. They all should know better. I don't get to bent out of shape about the jet skiers, pontoon boating old farts, etc.....most of the time they are just ignorant of what we are doing, and a polite conversation addressing their behavior usually leads to an understanding of how what they are doing is discourtious to other people on the water.
