The DADI DUSV 8 is a high-performance, M-Shape monohull Unmanned Surface Vehicle engineered for the most demanding aquatic environments
The DADI DUSV 8 is a high-performance, M-Shape monohull Unmanned Surface Vehicle engineered for demanding aquatic environments. Built with advanced Macromolecular Polyester Carbon Fiber & Kevlar, it provides unmatched durability and anti-wind/wave stability. Featuring a massive 50kg payload capacity, 38km operating range, intelligent obstacle avoidance, and a hot-swappable dual-battery configuration, the DUSV 8 is an autonomous multi-purpose platform for professional marine surveying, environmental tracking, and search & rescue (SAR) operations.
50kg Massive Payload Capacity
Engineered with a high-displacement M-Shape monohull capable of carrying heavy instruments up to 50kg with a shallow 10cm draft.
Carbon Fiber & Kevlar Construction
Formed from macromolecular polyester carbon fiber and Kevlar composite for superior structural integrity, IP67 rating, and resistance against harsh marine environments.
Extended 38km Operating Range
Powered by hot-swappable 33.6V 25Ah dual batteries supporting long-duration missions with up to 7 hours of endurance at 1.5m/s.
Smart 120° Obstacle Avoidance
Integrated 120° × 120° horizontal and vertical radar detection system identifies obstacles up to 20m (expandable to 40m) for safe autonomous navigation.
Weed-Resistant Propulsion
Features semi-embedded ducted thrusters powered by 1100W brushless motors with weed-resistant and easy-clean design.

The platform is ideal for Hydrographic & Bathymetric Surveying (underwater topographic mapping using multibeam/single-beam echosounders), Environmental Protection (carrying multi-parameter water meters, samplers, TP&TN analyzers), and Search and Rescue (SAR) (emergency response via side-scan sonars & 360° night cameras).
The modular bay supports Acoustic Doppler Current Profilers (ADCP), Multi-Beam & Dual-Frequency Single-Beam Echosounders, Side-Scan Sonars, Sub-Bottom Profilers, Multi-Parameter Water Quality Meters/Samplers, Total Phosphorus & Nitrogen (TP&TN) Analyzers, Laser Radars, and Gas Detectors.
Using iSAIL Intelligent Software, the vessel offers multi-route planning, breakpoint continuation, real-time depth/quality visualization, and post-processing echo stacking. Safety functions include automated Return-to-Home during low battery or signal loss, abnormal speed alerts, and 120° obstacle avoidance.
