A dog has miraculously swum to shore in the dark and been found alive after a boat flipped off Sydney's North Harbour, as the search continues for a missing fisherman.
A 25-year-old 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 life savers on jet skis and taken to Little Manly Beach where he told police his boat flipped during a test drive, throwing him, his 49-year-old friend and a dog into the water.
