Team New Zealand have taken a risk with the selection of Ben Ainslie Racing as their semifinal opponent in this week's America's Cup play-offs, but the pay-off for that gamble could come in the form of gains in that crucial starting box if the Kiwi crew can learn through that period.
I don't know if it came into Emirates Team New Zealand's thinking at all, but Ainslie, the British skipper, has the best starting stats so far in this regatta. Team NZ helmsman Peter Burling and his afterguard are still learning that part of match racing and it will be one of the key areas identified for improvement after the round robin stages.
Ainslie will deliver an intensive learning experience for the team. This will give Team NZ a chance to do a number of races against a guy who is very aggressive - as they can expect Spithill will be if they advance to the Cup match - and I think that's good for them. They're still learning the game of match racing at this level.
The risk is the Brits have shown significant improvement over the latter stages of the round robin after tweaking the configuration of their boat. I still don't think they have the pace of Team NZ, but as we saw today when BAR hung on to beat Team Japan, speed isn't always the defining factor. The Kiwi-led Japanese syndicate were quicker - Ainslie just sailed smarter.
The weather forecast would have had the biggest bearing on Team NZ's decision to select BAR given when they raced Ainslie in the second round robin it was light, as it is looking tomorrow, and Team NZ were really dominant.
