Pupils from Years 3 and 4 made model boats from recycled materials to race at the weekend.
Thirty local businesses and organisations sponsored the boats to help raise funds for school. The children came up with their own designs, incorporating flags with the logos of the boat sponsors.
Members of the Felton School Friends Association went along to help.
The race will take place on the River Coquet in Felton, near the bridge, starting at 4pm on Sunday.
It will be held alongside the annual duck race. Duck race tickets are available at Felton Fair Day on Saturday or before from the Running Fox bakery, Gallery 45 or Hair Naturelle.
