SL 20 Autonomous Survey Boat: Precision, Portability, and Purpose on Every Mission

In the realm of hydrographic and environmental surveying, the SL 20 Autonomous Survey Boat is a quiet disruptor—small in size, powerful in capability, and purpose-built for shallow water precision. Designed for surveyors who need reliable results without the bulk, it blends autonomy, agility, and advanced data collection in a lightweight package.

Built to Go Where Bigger Boats Can't

Weighing only around 17 kg, the SL 20 is easily deployable by a single operator. Its compact form makes it perfect for quick launches in narrow rivers, remote lakes, and hard-to-reach reservoirs. Whether working from a car, a dock, or a raft, surveyors get straight to business—no heavy lifting, no elaborate prep.

  • Jet pump propulsion for smooth operation in shallow waters
  • Compact hull design enables agile maneuvering in tight spaces
  • Streamlined setup for fast field deployment

Autonomous Intelligence at Your Fingertips

Forget manual steering—the SL 20 handles routes on its own. With intuitive mission planning software, users can pre-program survey paths and let the boat do the rest. Real-time feedback and collision avoidance systems help it steer clear of trouble, even in crowded or unpredictable environments.

  • Autonomous route navigation with intuitive controls
  • Onboard obstacle detection and live video monitoring
  • Shore-based control via laptop or remote controller

Data Accuracy That Professionals Trust

Despite its size, the SL 20 is no lightweight when it comes to data. It’s compatible with top-tier sensors including single-beam echo sounders, RTK GPS, and water quality instruments—ensuring precise results for bathymetric mapping, sediment analysis, and environmental research.

  • Supports industry-standard survey sensors
  • Delivers professional-grade accuracy
  • Works reliably in low-depth and high-complexity zones

Eco-Friendly and Efficient

Running on electric propulsion, the SL 20 is both quiet and clean. This makes it ideal for ecological surveys, wildlife habitats, and urban areas where noise or emissions would interfere with results—or local regulations.

  • Zero-emission electric drive
  • Low noise output for sensitive environments
  • Extended operational time with energy-efficient systems

Use Cases That Span Industries

From mining pits to disaster zones, the SL 20 is built for versatility. Whether it’s checking sediment buildup, inspecting reservoirs, or responding to emergencies, its adaptability makes it a must-have for survey teams on tight schedules and tougher terrain.

Common Applications Include:

  • Hydrographic & bathymetric surveys
  • Water quality analysis
  • Sediment and silt studies
  • Emergency and post-disaster mapping
  • Inland navigation and infrastructure projects

Why the SL 20 Is Gaining Ground

Professionals across sectors are embracing the SL 20 for more than its specs—it’s a strategic tool that saves time, keeps teams safe, and delivers consistent results without complications.

  • Portable and deployable by one person
  • Reduces manpower, fuel cost, and survey time
  • Ideal for routine missions and rapid-response scenarios

Whether you’re a survey veteran or a field team leader managing tight timelines, the SL 20 is your reliable co-pilot on water. It’s not just another robotic boat—it’s a smart, compact vessel built for the realities of modern data gathering.
