For CalCOFI cruises on ships not equipped with built-in EK60 acoustic transponders or CUFES fish egg pumps, it is possible use to use SIO’s pole-mounted CUFES or EK60. The SIO system requires attaching (bolting or welding) a plate (roughly 6” x 24” x 1” steel), amidships just above the waterline, to which a standoff is bolted. Another standoff clamp is attached to the gunwale directly above the lower standoff, and two pairs of guy-wires run fore and aft. The welding of an attachment plate was performed on SIO ships at our Marine Facilities with a machine shop adjacent to the pier.

A similar installation was done on the RV Nansen (Norwegian ship off southern Africa in 2003) for CUFES (the Continuous Underway Fish Egg Sampler). Either CUFES or the EK60 makes use of the same standoff and gunwale installation. On the RV Nansen the gunwale clamp was welded to the gunwale but typically it is bolted to the gunwale. The RV New Horizon uses a pole-mounted CUFES system but the EK60 transducers are installed in the hull.
