The yellow lines show the race area for the New York America’s Cup World Series, with spectator boat areas to the north and south.
The America’s Cup World Series comes to New York this weekend. Thursday is a training day, with practice racing on Friday. Official racing will be on Saturday and Sunday from 2 to 3:30 pm. This New York Times article gives info on where to watch. It mentions watching from the Statue of Liberty, but that is at least a mile from the closest part of the race area. You’ll be better off watching from the event village at Brookfield Place. You could also try to book a table next to the window at the restaurant in the Hyatt at Exchange Place in Jersey City, right next to the PATH train station. Circle Line offers a spectator cruise with two levels of ticketing are available – a Spectator Ticket and a VIP Ticket. Information here.
