We've always known that America's Cup World Series racing isn't for the faint of heart, but this new teaser shows the sailing at a whole new level.

The sailing series returns to San Francisco in a couple of weeks, from October 3-7, during Fleet Week, no less. Check out the America's Cup website for more details.
