Took a 7 lb barricuda on the Gentleman on Saturday which took the pot. I had several answers regarding this question. One regular passenger said 20%. The deckhand said 50% and said if you give us all we will let you ride next time for free. The pot was $120 and not wanting to offend anyone I gave $50 plus tips for fish cleaning and the galley maid. I didn't really care about the money as I was just happy to FINALLY catch a jackpot fish.
