SL40Y

The SL40Y is a compact, remote-controlled USV tailored for discharge monitoring, bathymetry, and velocity profiling. Designed with a trimaran hull and electric water-jet propulsion, it combines high-speed performance (up to 10 knots) with resistance to entanglement from debris and aquatic vegetation. The SL40Y supports quick deployment of sonar payloads like ADCPs, echosounders, and side-scan sonars, with tool-free installation into its built-in moonpool. This USV is ideal for single-operator missions in inland rivers, reservoirs, and industrial zones where autonomous ops are not needed.

It does not support autonomous navigation but enables rapid launch, maneuverability in shallow/urban waters, and tangle-free operation. The built-in moonpool allows fast mounting of payloads, streamlining mission setup and improving operational safety in polluted or weed-heavy waterways.
