Sailor Tom Singsby commended the recently released Team New Zealand monohull design describing it as 'radical' and 'amazing.'
The Australian was part of Oracle's success in 2013 and believes the monohull which features twin canting T-foils will revolutionise the sport.
"I had got a few tip offs as to what it may look like - yeah it just looks like an amazing boat and I think it will be pretty fast," Slingsby told Newshub.
Slingsby was aboard Oracle earlier this year for the 35th America's Cup, where they were beaten by Peter Burling and the Team New Zealand crew.
The 33-year-old was surprised at Team New Zealand design co-ordinator Dan Bernasconi's claim the boat could be faster than the impressive speeds achieved in Bermuda.
