P&O Cruises’ small ship Adonia today returned to the fleet in Southampton after a year on secondment to social impact brand Fathom.

The revamped adults-only ship will start a series of “discovery” itineraries beginning with a seven-night cruise to Bordeaux, Honfleur and Guernsey.

The 704-passenger Adonia operated for Fathom to run the first US sailings from Miami to Cuba in 50 years from last May, alternating with departures to the Dominican Republic.

However, the Fathom brand no longer has a dedicated ship with the social impact activities spread across other ships operated by parent company Carnival Corporation.

The cruise giant stressed that it would maintain cruises to Cuba despite US president Donald Trump rolling back trading freedoms with the island introduced by his predecessor Barack Obama.
