What makes Crystal Cruises' fleet unique is their size when compared to other luxury brands. Crystal's ships tend to be more mid-sized, yet they offer high standards as far as personal service, appeal to more sophisticated passengers, have advanced technology, and offer more unique itineraries. Crystal Cruises' fleet currently include the Crystal Symphony, which is a 940 guest, 50,000-ton ship as well as its Crystal Serenity, which is 68,000 tons and can accommodate 1,080 guests.

When introduced in summer of 2003, the Crystal Serenity was christened by Dame Julie Andrews. Crystal Cruises' ships are six star rated, and feature Asian and Italian specialty restaurants as well as a lavish Feng Shui spa. Their group cruise itineraries are worldwide.
