Behind the wheel of the six litre displacement boat Impulse, Mason won three major races in the two day program, the Brian McCosker Liberty Cup, the Victor Currie Invitational and the Australian Unlimited Championship for displacement boats.

Mason was also second in the Geoff Stevenson Memorial and third in the King of the River, the final event on the program.

He's been a regular at the Easter meeting in recent years, but this is by far his most successful campaign.

"He's a bit of a shy bloke - he doesn't say much, but he had a great weekend,'' Taree Aquatic Powerboat Club commodore Laurie Dege said.

"He even beat a few of the big boys.''

Mason beat Too Addicted and Xplicit in the the Liberty Cup. This is held in memory of Brian McCosker, who was killed racing at Taree during the Easter Classic in 2010.

Mr Dege hailed the weekend as 'a great success,' with huge crowds drawn to riverbank vantage points.

"It's always hard to gauge crowds, but I'd say it would be close to a record,'' Mr Dege said.

Parking was at a premium in central Taree for the two days.

"We were lucky with the weather and the conditions,'' Mr Dege added.

"There was a downpour on Saturday and that delayed the program a bit, but otherwise it was fine.''

He said the club was able to complete the full program.

Penrith racer Greg Banks also had a successful weekend. Driving GBR, Banks won the Stevenson Memorial along with the King of the River.

"He was quick,'' Mr Dege said of Banks.
