The America's Cup World Series are preliminary match/fleet race regattas used as heats in the lead up to the 2013 America's Cup and the 2017 America's Cup.
The World Series uses AC45 catamarans, a one-design wingsail catamaran designed specifically for the event by Oracle Racing. The AC45 was conceived as a smaller version of the larger AC72 class rule which was used for the 2013 America's Cup. The class was modified in 2015 to incorporate hydrofoiling capability for improved performance, with boats achieving peak speeds of 37kt.
The AC45 has the following specifications:
Quit acting so friendly.
Don't nod don't laugh all nicely.
Don't think you'll up-end me.
Don't sigh, don't sip your iced-tea.
And don't say, "It's been a while..."
And don't flash that stupid smile.
Don't ask me how I've been.
Don't think I've forgotten,
you never liked that necklace.
So cordial, so rotten...
Kiss, kiss, let's meet for breakfast.
Don't show up so on-time
and don't act like you're so kind
Don't ask me how I've been.
Don't sit there and play just
so frank, so straight, so candid,
so thoughtful, so gracious,
so sound, so even-handed.
Don't be so damn benign
and don't waste my fucking time.
