Sir Ben Ainslie faces a race against time to get his boat back on the water after a day to forget at the America's Cup.
Ainslie's Land Rover BAR crew suffered 'catastrophic damage' to their wing in the opening race of their head-to-head tussle with Team New Zealand for a place in the challenger final, from which the boat that will face the American defending champions will finally emerge.
Ainslie's crew forfeited early in their first encounter with Peter Burling's in-form Kiwis and couldn't fix the problem before they needed to race again, retiring back to their boat shed where their shore team was expected to work through the night.
It leaves them two down in the first to five series, with two more races scheduled on Bermuda's Great Sound on Tuesday, where stronger breeze conditions are also predicted.
"It's a tough day for the team and an extremely bitter pill to swallow," admitted Ainslie. "It's hard to lose two races in that manner so early on, especially when you consider what is at stake.
"I've got a lot of belief that this is something we can come back from. We've had tough times in the past and we've been able to turn things around.
"We are analysing what went wrong and fixing the problem and we'll be back out on Tuesday and fighting even harder.
"When I heard the crunching sound it's all too easy to just ignore it and keep racing but it was the right thing to stop. Thank God we did because we'd be out their picking bits of boat out of the bay now if we'd tried to push on.
"I'm proud with how the team has responded to this situation and we'll come out stronger for it."
In the other challenger play-off, Sweden's Team Artemis - including British Olympic champions Iain Percy and Paul Goodison - and Team Japan shared a race a piece.
