Three men had initially travelled on a 60 horse-powered 23-footer boat from Wewak to Manus.
They left Wewak last Monday with sixty 10kg bags of betelnut however, their boat capsized, leaving them to drift at sea for three days before two of them were rescued last Friday morning.
Manus provincial police commander, Chief Inspector David Yapu, said one of them was found floating on the boat by fishermen from Lou Island.
The boat operator, on the other hand, managed to swim to Paia Island, between Lou and Baluan Islands, where he was rescued.
