A support supports a decoy device in an elevated position above the support with a post. The support comprises a platform member with a front edge and an opposite rear edge with longitudinal sides extending therebetween. The platform member has top and bottom surfaces defining parallel planes between the front and rear edges and the longitudinal sides. The front edge has a width dimension less than the width dimension of the rear edge. The front edge is generally pointed in cross-section. The platform member is formed from a material with sufficient buoyancy to allow the support to substantially float in the water with the decoy device mounted thereto. The platform member top surface has a mount adapted to receive the post of the decoy device. The platform member has a tether connector. The method of using the support is also disclosed.
