About

About REAV-25

HydroSurv’s REAV-25 is a 2.5-metre battery-electric USV for commercial survey work in ports, harbours and shallow shoreline environments. Its welded 5083 aluminium catamaran hull carries 50 kilograms of payload and has a 210-kilogram lightship displacement. Twin 2.5-kilowatt rim-driven pod thrusters provide a stated maximum speed of six knots.

A six-kilowatt-hour, 24-volt battery system supports day-work operation without onboard combustion emissions. The vessel is portable on a small trailer and includes a single lifting point for constrained launch sites. Radio, 4G/LTE and Starlink-ready communications can link it to an ad hoc shore station or remote operations centre. HydroSurv aligns the design with the UK MGN 702(M) general exemption for qualifying sheltered-water operations; actual use remains subject to the applicable survey and operating plan.
