Hurricanes are knocking down profits at cruise giants Carnival Corp. (CCL) and Royal Caribbean Cruises (RCL) — but Wall Street thinks they are still a worth a ride.

Despite four hurricanes this month that wrecked schedules and caused frantic upheavals for passengers, Deutsche Bank has boosted its ratings of both fleets and raised target prices of their shares.

Stocks of both companies held steady Wednesday in the aftermath of the storm's ravages. Carnival was down only 0.69 percent at $47.26, off 33 cents, and Royal Caribbean was down a mere 20 cents to $43.68.

Carnival, the world's largest cruise ship fleet, said yesterday that the latest storm, Hurricane Jeanne (search), would cut into fourth-quarter earnings by about 2 cents a share — in addition to the 3 to 4 cents a share loss caused by Hurricane Frances.

Royal Caribbean Cruises earlier estimated its financial impact from Frances to be about 7 cents per share, but didn't say when it would give updated estimates for the remaining storms.

Violent weather closed several Florida ports and forced cruise operators to shorten or change cruise itineraries, and also offer rebates or credits for future cruises.

Meanwhile, neither cruise line shows any sign of slowing down.

Carnival is buying four new luxury liners for $2.5 billion, the biggest order in cruise ship history, while Royal Caribbean is adding two new super-sized luxury liners.
