Abstract: The raft with a water displacing floor includes at least one peripherally disposed, inflatable tube. The raft includes a flexible floor which has a larger spatial area than the spatial area of the raft when the peripheral tube is inflated. The floor is attached to the raft along the floor's peripheral regions. When the raft is in an elevated, horizontal, free-standing position, a lower region of the floor hangs at least a distance fifty percent greater than the vertical cross-sectional dimension of the inflated peripheral tube. In other embodiments, the floor hangs a distance more than the vertical cross-sectional dimension of the inflated tube. The raft can be configured using two vertically stacked peripheral tubes. In such construction, the floor is attached at the interface between the two vertically stacked tubes. The method of enhancing the buoyancy of the raft includes buoyantly supporting at least fifty percent of the loaded raft with a displacement of water caused by the floor.
