The SL40 is a waterjet-propelled autonomous survey boat designed for hydrographic and bathymetric surveys and inspections. The SL40 weighs 42 kg and supports a payload of up to 25 kg of survey instrumentation. The waterjet propeller enables sailing speeds of up to 10 knots while reducing the risk of entanglement with water plants or debris. The vessel is equipped with an obstacle avoidance system and RTK positioning, and can be controlled through a base station or by remote control. Its trimaran hull design improves stability during high-speed operations.
Survey instruments such as ADCPs, echo sounders, and side scan sonars with diameters ranging from 5 cm to 18 cm can be rapidly installed into the central moonpool, allowing fast switching between missions. The SL40 can also be upgraded to a multibeam echo sounder solution that has been validated through repeated testing, with optional MBES models including the R2sonic 2020 and Hydro-Tech YH400P.
Survey missions can be pre-programmed through the base station computer, enabling autonomous operation with real-time data transmission, while manual remote control allows access to difficult areas. Radar sensors support intelligent collision avoidance within a 50 meter range, and real-time video is available in manual mode to improve navigation safety.
