A marine survey apparatus comprises a plurality of cables towed by a vessel, the plurality of cables including two deflected tow cables each connected to the towing vessel. A primary surveying tool is attached to a cable, which cable is attached to the towing vessel and a spread rope. The deflected cables are connected to one another by the spread rope. The apparatus further comprises a water engaging drag device, which is attached to and trailed behind the spread rope. An elongate flexible element extends between the drag device and the vessel. The apparatus includes a control means for controlling the elongate flexible member and the drag device attached thereto. The survey apparatus is steerable to position the at least survey tool in a desired location by controlling the at least one drag device.
