The cruise line operator Carnival Corporation could have another scandal on its hands as it has launched an internal investigation after passengers claimed one of its ships ignored pleas to rescue three fishermen they spotted adrift in the Pacific Ocean.

The story of the Panamanian teenage hotel worker who survived for 28 days adrift “in a 10-foot boat” made headlines around the world last month. His two friends died of dehydration before the boat was eventually rescued near the Galapagos Islands.

But now it has emerged that a cruise ship travelling from Ecuador to Costa Rica passed near the path of their fishing boat, Fifty Cents, which was allegedly spotted in apparent distress by three birdwatchers on board. The passengers claim they alerted the crew of the Star Princess, but it failed to stop.
