ABSTRACT:
An apparatus for supporting a seismic transducer under water adjacent a towing vessel includes an elongated substantially rigid towing arm. A lower connector assembly is operably associated with the towing arm for connecting a lower end thereof to the transducer. An upper connector assembly is operably associated with the towing arm for connecting an upper end thereof to the vessel. The upper connector assembly includes a first pivot arrangement for permitting the lower end of the towing arm and the connected transducer to be lowered into the body of water. The upper connector assembly further includes a torsional support structure for resisting rotation of the towing arm about a longitudinal axis thereof. Preferably the upper connector assembly also includes a second pivot arrangement for permitting the lower end of the towing arm and the connected transducer to move laterally relative to the towing vessel.
