Papua New Guinea's National Maritime Safety Authority has continued a search for survivors of a vessel that capsized on Monday.
The are no confirmed figures but reports say between 20 to 40 people are missing, feared drowned.
Some reports say 60 people were believed to be on the MV Nara when it capsized off the Rai Coast which is known for very strong currents.
But a Maritime Safety Authority Officer, Simon Tarak, says authorities suspect the boat was carrying more than double its capacity.
Mr Tarak says it's callous that a captain and crew overloaded the boat in the first place.
"It's just too way over, too way over. As to why they overloaded it? I have no clue whatsoever as to why they overloaded the boat. It's just totally uncalled for."
Simon Tarak says some survivors are recovering in hospital.
