The Captain gets the price of the charter, the mate/deckhand gets the tip (if there is one).
We pay our mate Gill $240 USD for a 12 hr. trip out on the Gulf of Mexico. We pay the Captain $1600 for the charter.
Gill works his butt off taking care of 6 anglers, and is a very nice guy! He deserves every penny of it. Mates work for low wages and count on the tips for a large part of their earnings.
