The event is in its 42nd year and more than 100 people will compete in a unique day of racing on the Thames.
"We always choose a local charity," said regatta chairman, Martin Fry.
"We're very pleased to have them on board and we will do what we can to help them."
The event has some serious races but its focus is on families, with a host of fun events, as well as entertainment on dry land.
The audience can expect to see brave ladies take the plunge into the river to be rescued in the damsel in distress event and the sight of floating tubs being furiously paddled in the bath race.
Dragon-boat races and the chaotic raft race, which sees crafty teams sink or swim on hastily built craft, will also return.
Events run from 9am-6pm and the regatta is held in Mill Lane.
