Scott Gardner from Outdoor Canada stepped up next and promptly boated an even bigger one. Then he went for more, and the next hit proved stronger. "Mutton snapper," said Poveromo, as the drag surrendered. Then line began melting off the reel. "Shark got it," he said. We waited for the break as the line peeled out, but just when the spool neared bottom, Gardner gained line. For 45 minutes he worked it skillfully, and when the leader came into view, Poveromo grabbed a 6-foot gaff, leaned 2 feet out over the gunwale, and extended his 3-foot-long arm, reaching for the fish as it surfaced 12 feet away, just close enough for us to identify it as a blackfin tuna pushing 30 pounds.
