To watch the greatest sailing race in multihulls, you should see it from a multihull. The Lagoon 560 would be the best setup for San Francisco. The perfect platform for San Francisco Bay, acres of room for a race day crowd plus nice and stable in what can be a bouncy SF Bay. Trick would be moorage but America's Cup is supposed to have a bunch of yacht moorages available according to the original plan. Not sure how much that has changed. I don't see them running an advertising campaign on "Get your spot before they are gone"
