① Large Capacity for Multi-function Instruments

Wider deck, bigger payload, supporting multiple equipment work simultaneously for underwater inspection, hydrography survey and oceanography survey.

② Longer Endurance, High Efficiency

· The internal combustion engine can extend the battery life to 72 hours.
· Long endurance enables round-clock inspection, feedbacking real-time data & video.

③ Advanced Design for Easy Configuration

· Small A-frame and winch support towing survey, cable length up to 200 meters;
· Foldable lifter protects instruments wet ends and offers greater payload capacity.

④ Stable Working Condition for Survey

· Excellent stability，roll range smaller than 10 degrees in SS4.
· Catamaran design significantly reduces swaying and spray foam, providing stable and quiet working condition for acoustic equipment
· Low noise electric Plug-in thruster, reduces signal-to-noise ratio by 20%

⑤ Autonomous Control with High Precision

· Radar, HD camera and AIS sensing enabling highly sensitive environmental perception
· Dual engine and dual propeller providing large torque, L25 can rotate in situ
· Able to navigate closely around constructions for zoom-in inspection
· Autonomous navigation algorithm, advanced obstacle avoidance algorithm and propulsion control algorithm

⑥ Auto Return

During a mission, if the L25 loses communication or is about to run out of power, it can automatically sail back to the designated location to avoid getting lost on the sea.
