Andoo Comanche skipper John Winning says his in-form supermaxi isn't invincible despite her convincing win in Tuesday's Big Boat Challenge, but his biggest rival disagrees.
The imposing supermaxi dominated from the start in mainly south-easterly breezes of around 12 to 16 knots, finishing the course on Sydney Harbour in 53 minutes 58 seconds, one minute 20 ahead of LawConnect.
Last year's Sydney to Hobart line honours winner Black Jack was further back, another one minute 17 behind.
Hamilton Island Wild Oats was the last of the supermaxis across the line in fourth, five and a half minutes behind the winner.
The race was the last of four in the Australian maxi championship, with Andoo Comanche taking out the line honours title.
She was first across the line in all four races but was disqualified in Monday's second race following a protest from Christian Beck's LawConnect after the boats almost collided.
"We came probably within a metre of our two masts hitting at very high pace and it could have been really bad," said Winning.
"I take full responsibility for how close it was and we've had serious talks in the crew of what went wrong.
"We've obviously made some mistakes. We had a close call yesterday which we got together as a crew and talked about how that happened.
"We're learning all the time and we can't get complacent, we can't get comfortable because when we do that's when mistakes will happen for us."
Beck suggested it would take an error from Winning for his boat to take line honours in the Sydney to Hobart.
"We could probably come second or fourth and I think we can only really win if Herman (Winning) makes a mistake and we live in hope of that," Beck said tongue in cheek.
"He needs to make a fairly big mistake otherwise we'll probably come second if its a wide boat race, if its a narrow boat race we'll probably come fourth."
LawConnect took out the overall title in the maxi division of the Australian maxi championship with UBM Group topping the mini maxi division.
The 70-foot Willow, which was the first non-maxi across the line on Tuesday in fifth place, took overall honours in the Big Boat Challenge in which 11 yachts competed.
Wallabies flanker and former captain Michael Hooper was on-board Willow where he was a grinder.
