A search and rescue operation will resume for a fisherman missing since the early hours of Saturday morning after he was thrown from a boat along with another man and a dog off Sydney's North Harbour.
The men, a 25-year-old and 49-year-old, launched the 3.5-metre runabout from Tunks Park boat ramp at Northbridge about 9pm on Friday, before running into rough seas and capsizing around 3am.
They clung to the boat for a while before the 49-year-old man drifted away.
The younger man was spotted by a local fisherman in the water near Dobroyd Head at Balgowlah Heights shortly before 4.50am on Saturday.
He was rescued by surf lifesavers on jet skis and taken to Little Manly Beach, where he told police his boat flipped with his friend and a dog on board.
The dog was found alive at nearby Cave Beach about 10.30am after the boat's fuel tank and rubber mats were earlier recovered about 3.7 kilometres off the coast.
The older man, who has no fixed address and is living in a camper van in the North Shore area, has not been found as of Sunday morning after an air, sea and land search was halted overnight.
A NSW Police spokesman told AAP the search will resume later on Sunday morning.
Inspector Andrew Veale said the two men have known each other for about two years, and the 49-year-old was interested in buying the boat from his younger friend.
There were no life jackets, lights or safety gear on board, but search and rescue teams were hopeful of finding the missing fisherman alive.
His friend is recovering after being treated by paramedics for hypothermia and injuries to his wrist.
