The swimming area at camp during the 1950s featured a "T Dock" and had the canoes docked at the swimming area. A diving platform was also located a little further out from the dock. The current dock has been in the shape of an "F" since the 1970s. There is also a floating dock further out in deeper water. Swimming at Camp Coker is done in Lake Westwood. There has never been a swimming pool at Camp Coker. Camp Coker used to have a marathon in which troops competed in a foot race, archery, rifle, obstacle course, rowing, canoeing, and swimming. The marathon began at the spillway and ended in the nearby swimming area so a spectator in that vicinity could see the beginning and the end of the marathon. Another program feature for adult leaders in camp was the greased watermelon where adults tried to put a greased watermelon into a canoe in the nonswimmers area. The sight of adults trying to hold on to a slippery greased watermelon provided many laughs. Another program feature for boys was the war canoes in which boys went in the lake in two canoes with fire buckets but no paddles. The object was to swamp the other canoe by bailing water into it.
