Freestyle canoeing is the same as freestyle kayaking except the canoeist kneels in the boat and uses a single bladed paddle whereas kayakers sit in the boat and use a double bladed paddle. The C1 (canoeing) discipline uses the same boats as K1 (kayaking).
OC1 (open canoeing) have slightly larger boats and do not have a spray-deck to enclose the cockpit. Freestyle Open Canoeing is about moves on flatwater, and paddlers will often perform a routine to music.
