Speculation is mounting about the boats Team New Zealand will choose for the next America's Cup.
While some are hooked on the foiling catamarans used in Bermuda, others want a return to the traditional monohull match racing.
But an America's Cup legend is suggesting a fascinating compromise, the foiling monohull.
The man behind the Louis Vuitton Cup, Bruno Trouble, told the AM show it's a possibility.
"The money we have all invested in catamarans, foiling catamarans, if you make the same research in monohulls, [it] would be fantastic you have some extraordinary monohulls with foils, it's going around the world, like comanche or some others."
Many sailing experts agree that the foiling catamarans used in the last two cups would not be stable enough for the Waitemata Harbour's fickle weather. But at the Tauranga club where Peter Burling's moth dinghy is tethered, young yachties say foiling is where it's at.
"Normal sailing's [like] just starting to crawl," one budding sailor says. "As soon as you get into foiling it's like starting to stand up and run. Finally you just get this awesome feeling when the water goes quiet and you get straight into it."
"I think it's kick started the foiling generation," another says. "Last year we didn't have any foiling boats and now we've got three running round the harbour."
Grant Dalton has hinted at a return to monohulls to even the playing field.
However sailing commentator Peter Lester says an element of foiling appears inevitable.
"The foiling technology's being applied in junior classes, Olympic classes and of course in the America's Cup… I think the foiling technology will play its part in the next America's Cup."
All options are still on the table - for now.
