Abstract: A floating shelter has a semicircular frame defining an open-ended tunnel with an unobstructed ingress and egress. The frame has straight frame members forming the base of the open-ended tunnel. The roof of the open-ended tunnel is formed by curved frame members working together with a canopy top. A tensioning assembly mounted to each bottom corner of the canopy top engages the curved frame members forming the entrance and exit of the tunnel. Floats are fitted about the straight frame members forming the base of the open-ended tunnel for flotation of the frame.
