Time Out says
A boat party and excellent vantage point all rolled into one, this annual trip along the Thames allows you to enjoy a waterborne dancefloor, DJs, entertainment and a great view of the Battersea Park fireworks display. There are prizes for the best fancy dress and a cash bar on board so that the fun is at its fullest. You'll be returned to land at 9pm, but the organisers have lined up afterparties for those who don't want an early night. Booking essential.
