America's Cup: Am-Cam video Oracle and Emirates Team NZ in breeze

Running around the front of the wingsail - 34th America’s Cup - Oracle Team USA on the Bay

More video action from San Francisco Bay as Oracle Team USA and Emirates Team NZ went through a couple of hard training sessions in the AC72's in fresh conditions.

Both teams look very slick. Bad news for Emirates Team NZ fans is that it looks like Oracle have improved their gybing - although the gybes seen are rounding up to head to windward or on a reach, rather then the ones from Emirates, which are changing of course as part of a long downwind leg.

Bear in mind that these moves are done in fresh winds, so the AC72's power up very quickly, without the belly-flops that we have seen from some as they go around the corners in lighter winds.

Plenty of close ups. Each video is about eight minutes long.
