One late-summer morning, three friends—Martin Scanlan, Wyatt Morse, and amateur filmmaker and first-time tuna fisherman, Griffin Buckwalter—loaded up and departed Cundy’s Harbor in Harpswell, Maine, at 6:00 a.m. By 7:30, they were surrounded by whales and marking plenty of bait in 200 feet of water. They quickly jigged up some Atlantic herring and dropped anchor some 12 miles off the Portland coast. The gear was set out: one bait ballooned on the surface and the other approximately 90 feet down. The teens were marking a few fish and settled in as Buckwalter tried his hand at some haddock fishing. After an hour or so, the band on the down rod snapped, and the rod holder was almost ripped from the gunwale. They were on. It was 10 a.m.
