If you give the entire jackpot to the crew, then why get into the jackpot in the first place??? It's kind of like buying a lotto ticket, winning the lottery, then giving all your winnings to the establishments that you've bought tickets from in the past. The analogy is a little rough, but you get the picture. If you are a regular on a boat (as in going out every week or two) I can understand donating your winnings to the crew, especially since they'll probably treat you well every time out and give you free passes. If you are an infrequent passenger on a boat, then this doesn't make much sense. It is customary and appropriate to donate a discretionary portion of the jackpot to the crew. But, the bottom line is this, you can ALWAYS tip the crew (I always do and everyone should) after fish cleaning or at some point during the trip!
