A stagnant economy, threat of overcapacity and canceled cruises due to repairs and late deliveries have conspired to slow the hyper-growth cruise industry has enjoyed for the past decade. Even last year's new Millennium, which burst onto the cruise scene with its new gas turbine propulsion, had its share of troubles. Despite unparalleled reassurance by Celebrity that Millennium's propulsion problem was remedied, Infinity, its sistership, which was delivered this past Spring, recently experienced new problems with faulty bearings in its propulsion system — forcing the line to cancel two weeks of sailings. In addition, Celebrity's Galaxy dealt with a damaged propeller, causing lost money and cruises on that vessel.
