REAV-35 | Inland

Survey boat on trailer for hydrographic data collection at HydroSurv.

REAV-35

New for 2026, HydroSurv’s REAV-35 is a small-to-midsize, battery-electric USV developed for inshore and sheltered open-water operations requiring increased payload capacity and endurance. The zero-emission platform combines a 24kWh battery system with twin steerable pod drives.

Fully welded marine-grade aluminium alloy hull, delivering a robust and stable platform with generous payload capacity for inland and inshore survey and data collection operations.
Zero-emission, 48vDC battery-electric powertrain with 24kWh capacity, enabling extended endurance while supporting power-intensive commercial payloads.
Twin 5 kW independently steerable electric pod drives with rim-driven propellers, optimised for precise manoeuvring, shallow-water operation and use with towed sensors.
Readily transportable design, well suited to commercial day-works or remote stationing supported by fixed or mobile charging infrastructure.
Fills the capability gap between compact battery-electric USVs and larger seagoing platforms, providing an economical entry point to higher-endurance operations.
