Luna Rossa has made history today - taking their first point in America's Cup finals against Emirates Team NZ, thanks to an inexpensive battery pack.
The Italians levelled 1-1 in the first-to-seven Louis Vuitton Cup final yesterday after Team NZ were left dead in the water by a hydraulics failure as the Italians ran away with a gift victory delivered when Team NZ were leading them by 400 metres.
Team NZ worked hard to trace the fault, later named as a battery pack which powers the electronics which control the hydraulics for operating the wingsail and the daggerboards.
"Without the hydraulics, these yachts are unsailable," said tactician Ray Davies later. "You can't camber the wing or control the daggerboards."
Team New Zealand fixed the problem by replacing the battery pack with a new one but that meant they were technically disqualified for receiving assistance from their chase boat. Davies said they had to ensure their equipment was right; they did not want to add weight by carrying spare batteries.
Before that, it all appeared to be going to plan. Team NZ won a close start and produced a 10s lead at the short first mark. The boat speed of the Kiwis was apparent again on a hazy, choppy day on San Francisco Bay, gybing faster and producing superior sailing in avoiding the worst of the currents while finding the best of the wind.
