INEOS Britannia is a British sailing team that is the challenger of record for the 37th America's Cup.
The team was established in 2012 with the ambition of winning the America's Cup for Great Britain and to 'bring the cup home' to the United Kingdom. The team joined forces with INEOS in 2018. In 2021 the team challenged for the 36th America's Cup in Auckland, New Zealand, representing the Royal Yacht Squadron.
The team is owned and backed by INEOS founder and chairman Sir Jim Ratcliffe and led by the most successful Olympic sailor of all time, Sir Ben Ainslie, who is team principal, CEO and skipper.
