There are 16 boats waiting to take up to 128 movie lovers out onto the water, with films being shown on a 6x3m LED screen and audio enjoyed through noise cancelling headphones.
If sailing isn’t for them, guests can also enjoy films from the comfort of dry land in deck chairs in the square.
The line-up will include family favourites such as Toy Story and The Lion King, as well as sing-a-long screenings of Grease, Rocketman and The Greatest Showman.
Tickets for the experience are on sale now. They can be bought here.
It’s the latest cinematic venture in the capital, with open air film screenings and drive-in events taking place after lockdown.
