Abstract: A water teeter-totter is provided having a seating member for two or more persons. The seating member is pivotally mounted to a floating, buoyant support member, such as one defined by a pair of pontoons. The seating member is rockable relative to the floating support member by seated persons in a seesaw motion. In an embodiment, a propeller or other mover is operably connected to the seating body and propels the water totter device through the water upon rocking of the seating member relative to the floating support member(s).
