In its short time as a cruise line, Fathom made history as they marked the return of cruises from the United States to Cuba following the improvement of relations with Cuba and the United States.

Fathom will cater to an under served market of consumers who want to have a positive impact on people’s lives, and aren’t always sure where to begin.

[1] Fathom was initially established by Carnival as a cruise line on June 4, 2015,[3] to operate "social impact travel" journeys lasting seven days from PortMiami, Florida, to the Dominican Republic.

[7] Upon the brand's discontinuation, the website was shut down and redirected visitors to Carnival's Global Impact page until the domain expired.

Fathom's president was Tara Russell, an entrepreneur who founded Create Common Good, a nonprofit enterprise that provides food service job training to help at-risk people become self-sufficient.
