Crightons sponsored the festival for the first time in May. The festival takes place annually on the River Nene beside the Key Theatre and is one of the largest charity dragon boat events in the country.
Iain Crighton, managing director of Crightons, said: "We sponsored the 2006 festival and enjoyed the experience to such an extent we have signed as sponsors for the next three. "Dragon boat racing is such a unique concept and the event is run in a very professional manner that suits our image. We are very happy to be working with Gable Events on this fantastic local event."
