Ultra-short baseline system model EASYTRAK Nexus
The Easytrack Nexus hydroacoustic transducer (ultra-short baseline system; USBL) is located in the starboard hull of the catamaran. During operation, the transducer is extended below the keel by a hydraulic outrigger to a distance of about 1 m while maintaining horizontal visibility of 360°. The USBL head's lowering/lifting system allows the transducer to be inspected both at sea and in port, without the need to dock the vessel, and the transducer can be safely stowed inside the hull for the duration of the survey.
