SL20
Autonomous Survey Boat
A compact and portable unmanned surface vessel for hydrology and bathymetric survey
Moon Pool Design
- The moon pool supports flexible deployment of different instruments like ADCP and echo sounder.
Autonomous Survey and Realtime Data Telemetry
- Both remote control and autonomous available, great line tracking capability.
- Base Station ensures easy setup on field, real time data telemetry.
Compact and Long Endurance
- SL20 is 1 meter long and weights 17 kg, it’s easy for one man to operate and transport.
- Powerful battery and low power consumption provides 6 hours of endurance at 3 knots.
Low Draft and Shallow Water Adaptability
With a low draft of 15 cm, the SL20 delivers perfect performance in shallow water survey.
High Speed and Well Protected Propulsion
- Waterjet propulsion system drives the maximum speed to 5m/s
- Safety protection avoids the propellers being intertwined with water plants or water debris.
