The Costa Allegra cruise ship arrives at Mahe Port on Seychelles Island March 1, 2012. The crippled cruise ship owned by the company whose giant liner was wrecked off Italy last month is being towed by a French tuna boat to the main island in the Seychelles, its owners said on Tuesday. An engine room fire on the Costa Allegra had knocked out the ship's main power supply in the Indian Ocean on Monday, leaving it adrift with more than a thousand people on board in waters vulnerable to pirate attacks.
