The cruise brand that promises to let passengers have a social impact will sail into the sunset

If you want to try out Fathom’s social impact cruises, you’d better act fast. The give-back trips aboard the cruise brand that Carnival Corp. launched last April will end this summer.

That’s not to say the Fathom “experience� will vanish, the company says, but more on that later.

Fathom promises a weeklong cruise for passengers who want to have an impact on people’s lives. Cruises are designed to be inexpensive and sail on a more intimate ship, the 704-passenger Adonia.

The sole destination is the Dominican Republic, where travelers arrive to help teach English in schools, work on building clean-water plants and help with reforestation. Prices on cruises from Miami are low (around $850 for an inside cabin for two people), and most on-board and land excursions are included in the price.

Last May, the cruise line added Cuba as a destination — not for social impact projects but for cultural tours. It was the first cruise ship to sail from Miami to Cuba in 50 years.

Now the Adonis will return to the British-based P&O Line for summer cruises. And Fathom experiences will expand “across our many Carnival Corporation brands sailing to the Dominican Republic and beyond,� a company statement says.

That means you can buy a social impact excursion for the Dominican Republic (and other destinations to be added in the future) on other Carnival Corp. lines, such as Holland America, Carnival or Princess.

Fathom’s cruises will continue until the end of May.
