Oracle skipper Jimmy Spithill says he's "not done yet" with the America's Cup.

Jimmy Spithill has confirmed he will take inspiration from Team New Zealand and try to win back the America's Cup.

Spithill has released his biography Chasing The Cup – My America's Cup Journey and used it to insist he wants to be part of the next regatta after finally losing his grip on the Auld Mug in Bermuda.

Many critics questioned whether the comprehensive loss by Spithill's Oracle Team USA to Emirates Team New Zealand would be the end of the highly-competitive 38-year-old Australian skipper in the Cup game.

GILLES MARTIN-RAGET /ACEA 2017 Jimmy Spithill had high praise for Team New Zealand's design innovations that freed up the work of his rival Peter Burling.

But Spithill said he didn't have to look far for inspiration both from his own sport and his love of boxing.

"Muhammad Ali won the world title three times which means he lost it three times too, and is the greatest boxer in history," Spithill noted in his final words in a compelling book.

"I'd like to be remembered for getting up off the canvas – not for hitting it. I've just come off copping one of the biggest hidings of my life, but I ain't no feather duster. Not done yet."

He harked back to a comment from his Oracle boss Larry Ellison following their crash in the leadup to the 2013 San Francisco Cup that demolished one of the syndicate's giant AC72s.

"Champions and champion teams always come back," Ellison told Spithill.

Spithill did exactly that, overseeing a remarkable comeback victory in San Francisco. But he also felt there were learnings he could take as the Kiwis gained revenge in Bermuda four years later.

"You only need look at ETNZ following their brutal loss in San Francisco in 2013. Clearly, this is a champion team and you can do nothing but have an enormous amount of respect for them to have been able to regroup, keep fighting, get stronger and return to winning in Bermuda.

"I still to this day believe more than ever that defeat is nothing but education."

Of the loss in Bermuda in June, Spithill wrote of his emotions immediately after the final race in Chasing The Cup – My America's Cup Journey.

"I was absolutely gutted. It is difficult to describe the feeling after a loss like that but I guess I would use the word 'empty'. No one really talked on board and we sort of withdrew into our own worlds. The entire team put everything into it, left nothing in the tank, but it still hadn't been enough.

"Through better sailing – starting, tactics, boat handling and maneuvering – and impressive boat speed, the better team had won the America's Cup."

Spithill talked up the genius of the Team New Zealand design, admitting they'd been out-thought by Glenn Ashby's "Game Boy" style control box for the wingsail, the cyclors, and Blair Tuke's ability to tune the foils by looking at a display screen while on his bike.

That had enabled his rival at the wheel Peter Burling to be "freed up and get his head out of the boat rather than being head down focussing on riding the boat at the target ride height".

"Ultimately we were too conservative in a lot of areas and as skipper I take full responsibility," he wrote.

Oracle were forced into a game of catchup they couldn't win.

Spithill reveals they made major changes to their foils in the week layover during the America's Cup final to try to catch up to the Kiwis who had won the opening four races.

"We went about trying to bring our up-range foils down-range. Simply put, our light-air foils were thicker and carried more wetted area than those of ETNZ. Our only hope was to bring our smaller high speed foils down range to match their area, and we did this by increasing span on our foils and eating into our engineering safety margins. We also went for the most aggressive rudders available."

He conceded that came at the risk of boat handling: "It was now very difficult to sail in a straight line, let alone manoeuvre, especially in the starting box, but we knew we had to take a risk."
