Asymmetric tow system for multiple linear seismic arrays

An asymmetric towing system for towing multiple linear arrays includes a tow platform and a single composite tow cable extending from the tow platform and having the multiple linear arrays connected both mechanically and electrically thereto. The composite tow cable is shaped by a hard streamlined casing and houses a load-bearing cable for mechanical connection to each array and plural individual array connections for establishing electrical communication between each array and the tow platform. A single depressor is connected to a distal end of the composite cable for spreading the composite cable in a substantially lateral direction from and to one side of the tow platform.
