At least they didn't slam into the committee boat, like Oracle 5 did at the pre-start of the first fleet race. Oracle 5 were forced to retire.
Both races saw numerous lead changes in the strengthening breeze on San Francisco Bay and yesterday's big winners finished down the field - Oracle 4 (Spithill) were seventh, Artemis White sixth and Artemis Red eighth.
Team New Zealand finished fifth in the first race, after having had a share of the lead at least twice.
But teams were able to make dramatic gains - and losses - often in short passages of time. On the third leg, Artemis White gained five places to round the mark in second, Korea lost three and Oracle 4 lost five.
On the next leg, Team New Zealand suffered the same fate, losing five places.
The drama continued in the second race of the day. Barker started well and led for long periods but that lead was never comfortable, particularly on the short-tacking upwind legs, and they finished third.
"The tidal currents make it a very one-way track and no lead is ever big enough," Barker said.
Tomorrow Team New Zealand face Oracle 4 skippered by James Spithill in the match race semifinal and two fleet races are also scheduled.
