Emirates Team New Zealand capsizes during the practice race of the America's Cup World Series San Francisco, incurring minor damage.

The last time Dean Barker and his teammates on Emirates Team New Zealand capsized their AC45 (in Newport in June) the ensuing drama of righting the boat from its bows-to-the-sky position proved more entertaining than the capsize itself. It was an experience that Barker admitted he'd soon rather forget.

I used to be one of those sailors who believed deeply in racing ... other people’s boats, especially when it came to big boats. Racing your own boat seemed like such a hassle (organizing and provisioning for lots of crew), as well as a potentially voracious, money-sucking, black hole (new sails, bottom jobs, and divers, just to name a few). So the biggest boat I ever owned and raced was a J/22. Even that was downgraded to my current race ride: a Laser. And I was content.

U.S. Sailing Team Sperry Top-Sider head coach Kenneth Andreasen (left) has a big job ahead of him trying to get the team to rebound from a medal shut out in Weymouth. Convincing talented young sailors like Women's 470 crew Sarah Lihan (right) to continue on the Olympic path will be crucial to the team's future success.

The first step for anyone looking to find the reason behind the U.S. Sailing Team Sperry Top-Sider’s dismal performance at the 2012 Olympics (no medals, just one top-five finish) is this: take a deep breath.

In fact, that’s probably steps two through 10 as well.

OK, with that out of the way, let’s move forward by looking at some of the most pressing questions hovering around this regatta.
