Divide campers into teams of three. Two people are paddlers and one person gets a small pail. Put the two paddlers in a canoe, but put the third team member (with the pail) in another canoe, with two paddlers from another team. Each canoe has two paddlers and a person from another team, with a pail. Upon GO, the race begins and the person with the pail tries to fill up the canoe, in which they are a stowaway, slowing it down with the water weight. The first canoe over the finish line wins.
