The appts. for sweeping a body of water, for example mine-sweeping, comprises a towing cable (2), a depressor (5) at one end of the cable, a pair of sweep cables (6,7) extending from adjacent the depressor, and a diverter (11,12) at the end of each cable. The diverter includes controllable hydrodynamic surfaces (25,26,36), a signal receiver, and a device for adjusting the hydrodynamic surfaces in response to received signals. The appts. pref. includes depth sensor so that the diverters may be caused to fly close to but out of contact with the bottom using a transmission device. The diverters may be tailess with swept back wings (32,33) with elevons (36) or may be of delta wing form with elevators (26) and a fin (24) with a rudder (25).
