The accident has hit sales too: both Carnival, the company that owns Costa Cruises which ran the Concordia, and its main rival in the cruise industry, Royal Caribbean Cruises Ltd (RCCL), have reported a drop in reservations.
The demand for bigger and bigger cruise liners comes as the industry bets on luxurious, floating seaside resorts as the best way to draw in customers.
Of the 13 ships launched last year, four of them were liners with a capacity of at least 2,500 passengers, and of the 15 vessels scheduled for launch this year there will be at least another five on this grand scale.
Nor is there any sign of the trend slowing.
In March, Mediterranean Shipping Company (MSC) ordered a 333-metre (1,066-foot) long cruise liner with a capacity of 5,700 passengers. Days later, RCCL ordered another designed for 4,200 passengers.
Compare that with the Titanic, the queen of the seas in its day: it was 270 meters long and capable of taking 3,300 passengers and crew.
Industry executives have been quick to put the Costa disaster in perspective, arguing that it represented the exception rather than the rule.
