Emirates Team New Zealand has taken a commanding 4-0 lead over INEOS Britannia in the America's Cup finals in Barcelona. The Kiwis won the fourth race by 23 seconds, showcasing improved performance from their AC75 monohull 'Taihoro' despite the British team attempting a new game plan focusing on speed. Ben Ainslie, the British skipper, expressed determination to push back, emphasizing that they can still recover from the deficit. New Zealand is on the brink of securing their third consecutive title, needing just three more wins, while the British team seeks to break their 173-year winless streak in the competition. The series has seen close races and contentious umpire decisions, with both teams showing resilience. The next races are scheduled for Wednesday, as the competition intensifies.
