"There's not a huge window, which is why it's a pretty big advantage for us to be on the water ahead of the British and the Italians, because their window is rapidly disappearing."
Team New Zealand wasted no time in trying to work out issues and identify changes, focusing on how the mechanical systems are operating before moving on the look at the boat speed and performance numbers.
The AC75 is a complex vessel, with a number of mechanical and hydraulic systems needed to work together for the boat to stay on its foils. Team New Zealand has had a few minor teething issues early on, including problems hoisting the twin-skin mainsail.
"Every new boat and, particularly, a new class presents problems – you can't predict everything, so there's been some minor issues, but nothing major and we're really pleased with how it's going," Bernasconi said.
"It took us quite a long time to get the sail up on the first day, then every day we've sort of halved the amount of time that's taken.
"We'll continue to learn little lessons there, but we never expected any of those systems to work perfectly straight out of the box. We've gone through several campaigns ad we know with every new boat you're going to find little issues but we're just glad at the moment, touch wood, there's nothing major.
"It's a relief for us that the boat works as it's designed to work; no showstoppers and the concept of the AC75 yacht seems to work like we expected and all the sailors are really excited about that."
