Editor's note: Fathom has ceased operations and is no longer in business.
Launched by Carnival Corporation in April 2016, Fathom is a totally new concept: Caribbean cruises that focus more on getting to know the local community than days at the beach.
The line’s sole ship, the 704-passenger Adonia, made history in May 2016 when it was the first passenger ship to cruise from the U.S. to Cuba in 40 years. The ship cruises out of Miami year-round, alternating between sailings to the Dominican Republic for volunteer tourism and sailings to Cuba for cultural immersion.
Adonia previously sailed as part of the U.K.-based line P&O, and while it was refit when it joined the line, the focus on these cruises is much more on the enrichment than on the ship itself, or even the onboard activities. Adonia does not have a lot of bells and whistles — you won’t find a casino or stage productions, and there is just one pool and a small spa — but it’s also the only ship that has an onboard storytelling booth and workshops on curiosity and social innovation.
