Abstract
Abstract A floating standing platform used as a lifesaving device. The platform includes a planar deck which is submerged in a body of water and anchored in place. U-shaped handles extend from the bottom of the deck while upright supports extending from the top of the deck support a pair of buoyant floats. The platform is anchored at a convenient place where a swimmer or the like in distress can reach the floating platform, and grasp the handles to hoist himself upon the deck to await rescue. A safety belt can be attached to one of the floats to secure the victim to the platform.
