Former McLaren team principal Martin Whitmarsh has joined the British challenger for the 35th America's Cup, Ben Ainslie Racing.
The Briton disappeared from the public spotlight after being ousted by McLaren following a disappointing 2013 Formula One season.
Whitmarsh will now take the position of chief executive officer at Ainslie. He will report to Ben Ainslie, BAR's team principal, and the board, on which he will have a seat.
The team is already associated with F1 thanks to a partnership with Red Bull Advanced Technologies and Adrian Newey.
"After 25 years at McLaren it's great to be able to turn my energies and experience to such an exciting sporting and technical challenge," said Whitmarsh.
"McLaren developed into a multifaceted business, and I hope that my experience will help BAR in its aspiration for a sustainable business model, along with the clear goal of winning the America's Cup and bringing it back to British waters."
Whitmarsh will join the team in the final weeks before it moves into its headquarters in Portsmouth in April.
"I'm delighted that Martin is joining us," said Ainslie. "When we first started to put together the plan for BAR, McLaren were one of the aspirations. So it's particularly appropriate to have one of the original architects of that model as our new CEO.
"Martin came highly recommended by many authoritative figures in the motorsport industry, and already has good relationships with several of our key partners, particularly the head of Red Bull Advanced Technologies, Adrian Newey."
