Sig Hansen is the captain of the "Northwestern." When he docks his ship to restock for another crab season, he uses his Bank of America Cash Rewards Credit Card to earn one percent cash back on purchases, two percent cash back at the grocery store and three percent cash back on gas. And when he goes out to eat? He brings his card too...and hopefully he doesn't get served crab legs. Be sure to watch "Deadliest Catch" Tuesdays at 9 on Discovery Channel.
