Light winds have forced the postponement of racing at the Louis Vuitton America's Cup challenger series for the second time this week off Bermuda.
After two hours waiting for winds to reach a six-knot average threshold for racing, organisers finally pulled the pin just after 7am NZT and teams returned to dock.
"It is obviously not ideal that we have to postpone races, but that is precisely why we have spare race days in the schedule," said regatta director Iain Murray.
"Mother Nature is fickle, it is as simple as that, and since time immemorial, sailors have had to contend with light and strong winds.
"After four fabulous days of perfect conditions, today was our turn to deal with the light winds. I am, though, confident we will be back racing tomorrow."
