Did you ever work on such a boat? Asked the crew how much they earn? Whether they get social security, health insurance, orderly vacations? Most of these guys work hard for peanuts. It is not a PITA to tip them, it is an honorable way to show appreciation not only to the DM who showed you some nice fish, but also to the cook, they guy who cleaned your room and toilet, everyone of them works hard for low wages.Every boat I've been on has a tip jar. Generally, if it's a pita to tip, I dont.
No way I'm giving a week's tips to the club organizer. That's going to get skimmed.
And no, it doesn't get skimmed, but one can always tip the crew directly.
