The Cloud X, a 365-passenger fast ferry that has been operating between Port of Palm Beach and the Bahamas since August 2005, will discontinue operations at the end of May, the vessel’s owner said today. “Rising fuel costs and disruption of travel priorities caused by four hurricanes are among factors beyond our control that contributed to this decision,” said John Martin, owner of the vessel, which was operated by Party Line Cruise Co. “While we had hoped to overcome these challenges, and even though passenger levels have been slowly increasing, we recognized that we could not feasibly sustain operations under present circumstances,” Martin added.
