The America’s Cup World Series, San Francisco, is part of what is being billed as the busiest week of events in the city’s history. “We have a challenging program this week,” said regatta director Iain Murray. “We’re working with Fleet Week, so most of our racing will be later in the day. On Super Sunday we’ll be participating in the air show with Fleet Week. The air show will start and then stop, we’ll sail our Super Sunday fleet race (scheduled to start at 1:55 pm PDT), and then the air show will resume.
