If you were listening closely to the on-board action as Team New Zealand rounded the bottom mark in yesterday's opening race against Luna Rossa, you may have heard the call "Mr Whippy" ring out.
While the Kiwi boat was not really being put under pressure by the Italians at that point, it still hardly seemed the time to be discussing icecream. After all, as we saw in the opening race, in these super-fast hi-tech AC72 catamarans, one small lapse and the teams can find themselves in a spot of bother.
Fortunately, the Herald has discovered that wasn't the case at all - Mr Whippy is actually a codename for one of the crew's set moves.
Emirates Team NZ insiders have revealed the crew have recently recoded all their manoeuvres and have named the foil-tack, in which they round the bottom mark on foils and immediately tack away - a move they take great pride in - after the iconic icecream brand.
For now, the rest of Team NZ's codenames remain a closely guarded secret, but observers will be listening to the on-board microphones closely to see if they can unravel the strange Kiwi code.
