A yachtsman was lucky to survive 90 minutes in the water at Careys Bay last night.
His cries for help were heard by the crew of Port Otago's pilot boat Potiki.
The man, who lives on a yacht, was taken conscious, but suffering from hypothermia by ambulance to Dunedin Hospital.
Port Otago harbour control Calvin Whitty said Potiki had arrived back to its berth from a job at 7.33pm, and when the engine was shut down, the crew heard cries for help, about 100m away.
"They were able to shout back and locate him at his yacht," Whitty said.
