Searchers looking for two sailors missing aboard their yacht off the southern Queensland coast are heading to inspect debris found in waters off Coolangatta.
 
A RACQ CareFlight spokeswoman said debris had been spotted 65 nautical miles off the coast of Coolangatta and a helicopter was on its way to the area to inspect it.

But it was not known whether the debris was related to the missing 12.9-metre yacht Blessed Bee.

The search for missing yachtsmen was ramped up earlier on Monday with 21 aircraft scanning the eastern seaboard.

The two crew, who were sailing from Noumea, were last heard from on August 23 when they spoke to family members via satellite.

A spokeswoman for the Australian Maritime Safety Authority (AMSA) earlier said 15 fixed wing aircraft, two radar aircraft, three helicopters and a communication aircraft were all searching for the vessel.

The area being searched stretches from Bundaberg to Coffs Harbour.

The spokeswoman said one explanation as to why the men had disappeared without a trace could be that they had run out of power and had no communication capabilities.
