Captain Kerry Titheradge has been keeping busy since Below Deck season 11. He came into the charter season as the replacement for the franchises long-time captain, Lee Rosbach. After heading the series for 10 years, Captain Lee was not asked back for Below Deck season 11, likely because of concerns for his health. Hailing from Below Deck Adventure, it was unclear how Captain Kerry would fare in the new season. Nonetheless, he stepped up throughout his first charter season on the mainstay series with Fraser Olender serving as his Chief Stew, only letting go of two crew members all season.
