On my deep sea charters, we tip the deck hand 15% of the cost of the trip... if he's a good deck hand. That means there should be plenty of live bait, he should keep the fish picked up off the deck and put on ice, he should help unhook fish, and untangle lines. He should also be cheerful... if he's lazy and abusive, he don't get squat!!!... but if he's a good deckhand he'll get $225 cash for a 12hr. days work, plus he'll make 30 cents a pound on the people that want him to clean their fish... that's the weight of the uncleaned fish, adds up to $90 for 300 lbs. of fish... about $315 cash for a long days work.
