Overview

A survey boat one person can carry from one of China's largest USV makers, aimed at river, canal and reservoir bathymetry. Its 17 kg carbon-fiber hull carries an echosounder or ADCP through a central moon pool. SL20 images were on OceanAlpha's site by December 2018, so the launch year is estimated. OceanAlpha also makes the Dolphin remote-controlled rescue buoy and larger M-series survey USVs.
