The boat Hard Merchandise has remained a fan favorite despite trailing behind FV-Tuna.com and Pin Wheel, but in the season finale captain Dave Marciano stumbles upon a big herd that could help him finish strong.
"We've got one fish on the boat. That's good but we really need to get another one," Dave says in our exclusive clip. "Our window of opportunity is getting smaller and smaller."
While being threatened by a storm, Hard Merchandise gets a bluefin on the hook and fights to reel it in.
"If we don't get one of these fish, we may not get another chance before this game is over," says Dave.
Tune in for the Wicked Tuna season finale on Sunday, May 12 at 9 p.m. ET on the National Geographic Channel.
