The invention provides a retrieval device for retrieving floating objects from the surface of a body of water. The device comprises an extensible boom formed by a semi-rigid, non-resilient, buoyant cable and a grab device attached to one end of the cable. The cable is adapted to be stowed within a portable housing when not in use, and to be extended therefrom for use. The housing is a hollow, doughnut-shaped housing providing a toroidally-shaped interior passage adapted to accommodate the cable and to coil it as it is inserted into the passage.
