Team NZ and Team USA can't be separated for speed, leaving the America's Cup to be decided by sailing skill.
That's the view of Swedish syndicate team director Iain Percy, whose boat was eliminated by the Kiwis in the final of the challenger series in Bermuda.
Emirates Team NZ, who were beaten 9-8 in a memorable Cup Match four years ago, will resume hostilities in the best-of-13 final beginning on Sunday (NZT).
Team USA, who start with a 1-0 lead after winning the qualifying series, will be tough to beat, Percy predicts.
The American defenders won both races against Team NZ in that series, with their charismatic skipper Jimmy Spithill later outlining some of the on-water mistakes made by Kiwi helmsman Peter Burling.
