Out for a 10 hour tuna/shark combo trip. Arrived at the bluefin hill to find whales, birds and dolphins everywhere. Worked among the nature show for nearly two hours with a pull or even seeing a tuna air out on bait. Decided to troll back toward where I planned to set up for shark fishing. Less than a mile inside the whales our flat line gets nailed and we put a small bluefin in the box. A couple more passes and our bar gets crushed and another bluefin goes in the box. The next forty-five minutes produces three more misses before #3  finds the hook and is added to the box. Lines are pulled in and we make a 20 mile run and set up in hopes of a thresher shark. After ninety minutes and no pulls the guys decide to get their bluefins back in to the fish cleaner.
