A group of 12 passengers on a Baja Ferries vessel that ran aground and caught fire off Puerto Rico has lobbed a $41m lawsuit against the Mexican shipowner and charterer America Cruise Ferries.

The four families from the Dominican Republic and two Puerto Rican passengers are alleging physical injuries from the August incident on the 950-passenger Caribbean Fantasy (built 1989) as well as smoke inhalation, emotional distress and anxiety suffered during the evacuation of the vessel.
