ErikD,
I fish for the love of it. I've never over fished to catch and sell. I just catch some for fun and for the table.
It is possible to catch enough to offset the cost of the trip and maybe a couple of extra bucks but never enough to make a profit.
Thank goodness I can afford to fish the boat, because to fish for the money to offset the cost makes it a job and I already have one and don't want another.

Hopefully the boat gets fixed Thursday and we'll have a great tuna trip to celebrate. Tuna on the Bar B Que
