UPDATE: Rescue helicopter locates vessel with crew
UPDATE: A VESSEL with two men on board has been located by RACQ CQ Rescue.
The six-metre vessel is about 170km offshore from Hamilton Island.
An RACQ CQ spokesperson said the two men, both aged in their 30s had activated an EPIRB after their boat broke down early in the morning.
The EPIRB was let off at about 11am, after the men were unable to communicate to anyone that their boat had broken down.
The spokesperson said the crew had to refuel at Hamilton Island, and it took the rescue team about 25 minutes to reach the two men.
"They were along way offshore, there was lots of reef around and no land in sight," the spokesperson said.
"A crew member was lowered into the water and they then swam over to the boat."
The spokesperson said the men were 'fine' and would be staying with their boat and VMR would be taking over to assist in bringing them safely back to shore.

An RACQ CQ Rescue Spokesperson said the crew are headed to Ferry Reef near Hamilton Island.
