Royal Caribbean''s Icon-class ships are the largest cruise ships in the world, carrying over 7,000 passengers at maximum capacity. (Verify current title-holder — Legend of the Seas class additions may change this.)

There are roughly 300+ ocean cruise ships operating worldwide across major and specialty lines, with dozens more on order through 2030.

New ships launch every year — recent debuts include Norwegian Luna (March 2026) and new Icon-class and World-class vessels. (Keep this answer updated — it''s a freshness signal for the whole page.)

Ships with waterparks, kids'' clubs, and family staterooms — like Royal Caribbean''s Icon and Oasis classes, Carnival''s Excel class, and Disney''s fleet — are the strongest family picks.

A ship class is a group of ships built to the same design. Ships in one class share layouts, venues, and size, so knowing the class tells you most of what to expect onboard.
