The SL40 is a compact, high-performance USV designed for hydrographic survey missions in inland rivers, lakes, and urban waterways. Its trimaran design offers enhanced stability at high speeds, while the electric water-jet propulsion ensures debris avoidance and shallow-water operation. With its quick-swap moonpool supporting instruments from 518 cm in diameter, it accommodates multibeam echo sounders, ADCPs, and side-scan sonars. The SL40 is used in bathymetric surveys, pipeline inspections, and environmental remediation efforts, including dam basins and sewage detection.
