ADRIAN Bram has never seen the Whitsunday Sailing Club so busy.

In fact on Sunday night his major concern was whether the bar would run out of rum.

The reason for the sudden rush is the 26th annual Airlie Beach Race Week, which this year has been thrown open to the wider community with apparent success.

Mr Bram, the marketing director for the event, said the program of free live music every night had attracted sailors and townsfolk in their droves.

"And Sunday turned into one of the biggest days ever by combining the family fun day and running it straight into the Race Week festivities," he said.

"We saw a fantastic turnout from the community and the club's been doing very well every night both upstairs and downstairs."

On the water meanwhile, it's been a mixed bag, with what Race Week chairman Jim Hayes called "champagne sailing" for the first two days, dropping to a glass-off on Monday ahead of the mid-point lay day.

With the wind predicted to pick up to between 15 and 20 knots for the final two days, Mr Hayes said organisers were kept on their toes.

"It's cruising along really nicely but the changeability of the weather is keeping our race officers and the jury busy," he said.

Airlie Beach Race Week 2015 concludes tomorrow with a Big Bay Race making for spectacular viewing along the shoreline and a final party and presentation at the Whitsunday Sailing Club tomorrow night.
