A decoy control apparatus for organizing and displaying a spread of buoyant decoys in a free-surface marine environment, the decoy control apparatus including a pliant, water permeable sheet for subsurface deployment with a plurality of buoyant decoys attached thereto for surface display of the plurality of buoyant decoys grouped in a predetermined spread, a tethering assembly mounted to the sheet for removable attachment of a plurality of buoyant decoys thereto and a ballast attachment arrangement fixed to at least one end edge of the sheet for attachment of at least one ballast weight thereto to downwardly bias the sheet against the upward bias of the buoyant decoys, thereby stabilizing the sheet in a subsurface disposition intermediate the surface-borne buoyant decoys and the at least one ballast weight.
