Canbury Gardens was the venue for fierce competition once again as Dragonboat rowers vied for glory.
Super Mario, Batman and many others took to the Thames in a colourful display.
Organising committee member Simon Leo said: "It was fantastic, one of our best events that we've had so far.
"It was nice and warm, with a good atmosphere - not to mention the amount of money raised for charity.
"We're hoping it to be in the region of £100,000, which would be fantastic."
