Lets see.....a big open ocean....out on the Bank and you guys sit on top of this charter and start fishing??? Hmmmmmm.....sounds like maybe you guys needed to back off and not crowd him so much! First off.....personally...I don't fish in crowds....cause people suck! I would rather walk away from a blitz filled with idoits and fish in a quiet, all to myself spot and find my own fish. I never, ever set up close to another guy....its just not done by me though I know many do. You guys could not find a nice quiet place of your own out there in the middle of the ocean this time of year?
Sounds like you were piggy-backing.
As for their behavior.....inexcusible! If the Captain of the ship let his paying customers/buddies act like that he should lose his Captains liscense!
