Carnival (NYSE:CCL) share certificates should probably come with a dose of Dramamine these days.

Carnival stock is trading closer to its 52-week low than its high, and the same can't be said of rivals Royal Caribbean (NYSE:RCL) and NCL (NYSE:NCL). 

It's against this backdrop that the world's largest cruise line is set to report quarterly results on Tuesday. Carnival stock could use a boost, especially if its guidance for the seasonally potent summer quarter is encouraging.

In this video, longtime Fool contributor takes a landlubber's look at the various moving parts of Carnival heading into the report.
