The sinking earlier this month of the cruise liner Sea Diamond offers a timely reminder that holidays at sea are not without risk. The ship, operated by the Greece-based Louis Hellenic Cruise Line, sank on Good Friday off the island of Santorini, after it ran aground on rocks. The 1,156 passengers, on a four-day tour of the Aegean, included Americans, Australians, Britons and Canadians. All but two were rescued. The two who are missing, from France, are believed to have drowned. |
