The Federal Maritime Commission (FMC) issued a notice to cruise passengers affected by the Houston ship channel oil spill stating that several cruise voyages have been altered or rescheduled. Royal Caribbean International’s Navigator of the Seas seven-night Western Caribbean March 23 sailing was originally cancelled because of an oil spill in Houston harbor, but has decided to go ahead with a shortened four-night cruise. Carnival Cruise Line’s Carnival Magic departed March 25 from Galveston to begin a new cruise after being delayed as a result of the oil spill.
