Hell hath no fury like a Wild Thing scorned.

Two months after being disqualified from the 2012 Sydney-Hobart, veteran skipper Grant Wharington is back - with fire in his belly and a sense of injustice smouldering among his crew.

The Queenslander is competing in next month's Sydney Harbour Regatta - his first event since his 100-ft super maxi Wild Thing was controversially barred from the 2012 Sydney-Hobart over an alleged paperwork infringement.

And the March 9-10 harbour regatta is just the start of what promises to be a punishing 10-month schedule for Wharington and his crew as they aim for a shot at redemption.

"We're basically going to do every event we can between now and Christmas and get the crew really, really refined," Wharington told AAP.

"We think we're just going to be in fantastic shape by December and the 2013 Sydney-Hobart."

Wharington is still smarting from his Sydney-Hobart no-show, having spent millions of dollars modifying Wild Thing to compete with 2012 winner Wild Oats XI and other leading super maxis.

But the Cruising Yacht Club of Australia (CYCA) insisted the yacht's paperwork didn't comply with race rules and barred his boat three hours before the start gun.

Wharington says he's not spoken with the CYCA or commodore Howard Piggott since, but hinted there could be more to come in the saga.

"We haven't had any further discussions with them at this point in time," he added.

"But there certainly will be some discussions coming up in the future."

For now, any lingering resentment is set to be taken out on the water, with Wharington determined to show precisely how fast Wild Thing is.

"We think we've got the boat in a really good place in the way it's set up and we'll be racing hard and trying to see how competitive she is," he added.

The Sydney Harbour Regatta will be a useful hit-out for the super maxi and her crew, although Wild Oats XI and another key Sydney-Hobart rival, Ragamuffin Loyal, are overseas and won't compete.

The harbour race features 24 classes of boats split across nine courses. Entries closed on Friday.
