Helmsman Peter Burling hopes Team New Zealand persist with foiling catamarans for the next America's Cup.

The new holders will unveil their protocols for the Cup in September where the venue, design type and nationality clause will be finalised.

There has been talk the Cup could return to more traditional monohulls, but Burling wants to race in something fast.

"It would be a bit of a shame to step backwards in terms of the speeds the boats can generate, but I'm pretty sure we'll come up with a rule that will keep pushing that forward."

Burling also hopes the nationality clause is strengthened.

"You know it is a friendly competition between nations... I'm in favour of the nationality clause but I'm not quite sure how harsh it's going to be yet as to what percentage it breaks up at."

Burling has finished second overall at the Moth Class world championships overnight in Italy.
