After 34 years, Carnival (NYSE: CCL) CEO Micky Arison is stepping down as CEO of the world's largest cruise-ship operator.

Carnival's new CEO is Arnold Donald. He's a longtime board member, so he naturally knows the company and its present challenges well. He lives in St. Louis, ironically enough, far removed from the coastal ports that Carnival relies on for most of its sailings. 

This may be a peculiar time to step down. Carnival has had its shares of mishaps at sea since early last year, but the cruise line was starting to sail past floating blunders. Even the maligned Carnival Triumph resumed sailing earlier this months after months of repairs and updates.

So is this really the right time for Carnival to be letting someone else steer the ship?

Arison's Miami Heat won another NBA title a week earlier, so at least he's going out a winner on one front.
