Patent ID: 7837527

Claim:
A device for a body of water, comprising: a floating island having a curve, the floating island also having a bottom, the bottom being a widest part of the floating island; a buoyant section affixed to the bottom; a three-dimensional irregular dynamic weight section defined by and including an enclosed wall of substantially solid material that defines an enclosed cavity, the enclosed wall having holes through said wall distributed around said floating island including a plurality of upper holes in the dynamic weight section of the floating island and a plurality of lower holes in the bottom of the floating island, the floating island structured so that when placed in a body of water the curve normally projects out of the body of water to provide a floating island surface capable of supporting users climbing thereon while the fixed buoyant section is submerged in the body of water and the dynamic weight section is capable of supporting users climbing on the floating island surface while the dynamic weight section is above the buoyant section; and whereby in response to tilting forces imposed on the floating island by users climbing on or off the top surface of the floating island water can enter into and exit from an interior space of said floating island through at least some of the holes and thereby dynamically balance the floating island and preventing upsetting of the floating island.
