The heavier kayaker should sit in the back seat of the tandem kayak. This will balance out the weight of the kayak and allow the kayak to maintain a good level of buoyancy as well as ensure the traction keeps the kayak’s direction. The kayaker in the back seat plays the role of maneuvering and maintaining the kayak’s course. The kayaker at the front seat maintains the pace and speed of the kayak through paddling.
