These folks fought a two-hour battle on the Ken Matsuura titanium reel to boat a 513-lb giant bluefin tuna on a recent tuna charter. This fish pulled all the stops out, making the bow run, the dive, the pect fin caught in the line at one point. Captain and crew and luck prevailed as these guys landed this beauty late in the day. By the time this fish hit, the guys were all in practice after fighting a smaller bluefin tuna on a standup reel to the boat for a release. Certainly a full day of tuna fishing!
