Abstract: A portable flotation platform is disclosed for use in supporting a load of equipment, hunting dogs, or personnel above the level of a body of water. The platform includes a deck constructed to be of an overall density less than that of water and sized so as to support the load above the level of the water. An anchor device extends down to the bottom of the water and up to the deck to hold the deck on station in the water. The deck and anchor device are sized and shaped to nest together, so that platform has a carrying mode in which the deck and anchor device are held together to facilitate a user carrying the platform to and from a point of deployment at a body of water, and a deployment mode in which the deck and anchor device are spaced apart from each other to enable the deck to be positioned at the surface of the body of water and the anchor device positioned at the bottom of the body of water.
