The "whale tail" is the iconic, trademarked funnel design found on all Carnival Cruise Line ships. It features two large "wings" extending from the sides of the funnel, resembling a whale's fluke. While the design is a major branding tool, it is also highly functional; the wings are designed to deflect exhaust gases away from the ship's aft decks, ensuring that passengers lounging by the pool or on balconies aren't bothered by soot or engine fumes. First introduced in 1982 on the Tropicale, the design was created by Carnival's longtime architect Joe Farcus. In 2026, it remains the most recognizable silhouette in the cruising world. Some of the newest ships, like the Mardi Gras and Celebration, have even incorporated the "whale tail" into their top-deck features, such as the track for the BOLT roller coaster.
