Captain Mark Howard, a staple on the opening season of "Below Deck Mediterranean" has died ... TMZ has learned.
Howard died in Florida at some point in the last week, a family friend says his death was sudden and occurred while he was at home. We do not currently know any other circumstances surrounding his death.
Captain Howard appeared on 13 episodes of the show's first season in 2016. He was a respected figure of authority on the show, and always maintained the "customer is always right" attitude, yet was still very hands-on with all of his crew members.
