Princess Cruises is being sued by a Panamanian fisherman who spent 28 days adrift in the Pacific Ocean.

Adrian Vasquez has filed a lawsuit in Florida against the cruise line, alleging negligence after one of its ships sailed past his stranded vessel.

Princess Cruises has said it “deeply regrets” the incident.

However, the line argues there had been a breakdown in communication after passengers spotted the stranded vessel - the Fifty Cents - and told staff, but the captain was not informed.

Two passengers who saw Vasquez adrift close by are believed to be supporting his claim.

Vasquez and two friends had set out in their three-metre-long open fishing boat from the port of Rio Hato in February.

They were on their way back when the engine failed.

Two of the three died of dehydration, before Vasquez was eventually rescued 1,000 kilometres off the mainland, near the Galapagos Islands.
