No matter the written rule, there are just some who think they own the water. Had 3 boats ( one a charter boat) who if I didn't completely stop their boards would have hit my boat. Then one of them did a 90 deg turn right infront of me, causing me to stop and bring in all the lines while they set back up. Guess I'm back to have your snips ready and just cut their main line if they are that much of an a hole. It's not like there were any other boats even in the area. I've done that before, guy gave me the finger, ran his board into my boat, I grab the line and sniped it and gave him the one finger salute back. I just have NO tolerance for that kind of stuff when it's not caused by a crowded situation. One time I let it go, but come back and do it again, I'm ready for battle!
