The America's Cup challenger series final remains a seesawing contest between Luna Rossa and INEOS Britannia off Barcelona

For a third straight day, the British syndicate has won first race, only for Luna Rossa to then rebound in race two.

It's now 4-all in the best of 13 series.

Britannia helmsman Sir Ben Ainslie wonders just how long the tit-for-tat will continue.



Luna Rossa crashed out of race seven after a dramatic nose dive, but swift boat repairs meant the syndicate was match-ready for its victorious eighth race.
