lol........99% of the charter boats in my area offer a free trip if a giant is landed. School tuna are all yours if you want to keep them. There is a lot of meat on a 150lb tuna fish, and it doesn't freeze well, it's much better eaten fresh. I personally don't charter, I fish for them commercially and they have to be over 73" for me to keep. There's no guarantees with tuna fish though, especially in Cape Cod Bay. They're not always there for the taking. Offshore tuna charters (canyon fishing) are more productive. Fishing for yellowfin,albacore, and small bluefin, but they'll run you more money, and you can keep the fish!

You'd look pretty cute driving back to PA with a 1,000 tuna fish strapped to the roof!

Give the guys I mentioned an email, they can tell you more about what's involved. Have a good one!
