SL40

Technical specifications

Rugged Architecture for Field Operations

The SL40 is a thoughtfully designed compact USV built for real-world use.

Every component, from the hull to the propulsion system, was engineered for durability and efficiency.

Shallow-Water Navigation

With only 15 cm draught, SL40 can navigate and operate effectively in narrow inland waterways, shallow rivers, and coastal areas where conventional vessels cannot access.

Compact Portability

The SL40 features a compact carbon-fiber hull—about the size of a large suitcase (1.65 m × 0.55 m × 0.38 m) and weighing as much as two travel backpacks (42 kg with dual batteries).

Tangle-Free Propulsion

Powered by a debris-resistant waterjet thruster, SL40 reaches 10 knots while avoiding tangles in weeds and floating obstacles—ideal for messy shallow waters.

Enduring Operation and Quick Swap

With 8-hour endurance @ 3 knots and field-swappable batteries, SL40 powers full-day surveys without downtime.

Dual Control Options

The SL40 USV offers two control options, being operable via remote control for precise human intervention and equipped with an autopilot system for autonomous navigation and task execution.

Remote Control

• Radio remote control with handheld terminal
• Communication range up to 1 km

Autonomous Operation

• Autopilot under autonomous navigation
• Communication range up to 2 km

Wet Payload Flexibility

SL40 provides flexible deployment of wet-end payloads through two moonpool options:

• Compact 210 mm × 210 mm square moonpool
• Extended 210 mm × 275 mm rectangular moonpool

This enables seamless integration of surveying instruments including:

• Teledyne ODOM E20 SBES
• R2 Sonic 2020 MBES
• Kongsberg M3 MBES
• Valeport SVS
• YSI EXO2s
