America's Cup: Three teams, four AC72's in practice session on Bay

ETNZ, Oracle and Prada converge during today's practice session - America's Cup

Emirates Team NZ, Luna Rossa and both Oracle Team USA's AC72s were on the water today, taking advantage of a Reserve Day to get in some practice.

Skies were partially cloudy, with some sunshine getting through, with good breeze in the 12-15k range. A perfect day for the America's Cup AC72s. All photos by Chuck Lantz, one of Sail-World's on-scene photographers.

With Sail-World's other photographer, John Navas, shooting both stills and video from a photo boat, for variety Chuck shot from an overlook viewing area above Crissy Field, an area open for free public viewing throughout the LVC and AC events. As some of the photos show, the course is close enough to shore to provide excellent views along almost the entire San Francisco shoreline.
