Abstract
Abstract A floating chair moves forward, turn or drifts under control of a pair of on/off switches connecting a rechargable battery to power a pair of sump pumps which jet water from the rear of a pair of elongated floats supporting the chair. The battery is in a float which is behind the chair and extends between the elongated floats. A buoyant roller beneath the floats enable the unit to roll on dry land.
