The Dookyu Crown 22ft Aluminum Autonomous Survey USV is a 6.6m unmanned surface vessel configured for hydrographic survey, water-quality monitoring and routine inspection missions. Its compact aluminium hull combines a 2.2m beam with a 1.26m depth, while the control system supports switching between autonomous and manual driving modes.
This page is intended for buyers whose primary requirement is repeatable data collection rather than passenger transport. Sensor selection, navigation package, communications equipment and mission endurance are project-dependent and should be confirmed in the final technical specification.
Why this configuration suits survey operations
Autonomous and manual control: use planned routes for repeatable survey lines, with manual intervention available when local traffic or field conditions require it.
Electric propulsion: the listed X-12 12kW E-propulsion system supports low-noise operation around reservoirs, harbours and research areas.
Compact working platform: the 6.6m by 2.2m hull is suitable for projects that need a transportable surface vessel rather than a large crewed survey craft.
Project-specific integration: survey sonar, water-quality instruments, cameras and data links can be specified around the buyer's mission file; final payload and endurance depend on the selected equipment.

Typical survey missions
Hydrographic survey: repeated transects for depth and bottom-profile data when equipped with the specified sonar package.
Water-quality monitoring: scheduled sampling or sensor measurements in reservoirs, rivers and sheltered coastal waters.
Infrastructure inspection: visual or instrument-based checks around quay walls, bridges, intake structures and floating facilities.
Research support: remote observation where reducing onboard personnel exposure is part of the project objective.
What must be confirmed before quotation
Please provide the operating area, required sensors, survey speed, mission duration, communications range and launch/recovery method. These inputs determine the payload arrangement, battery capacity, navigation package and data-link architecture. Figures not listed in the confirmed table above are not fixed specifications and must be agreed in the project technical file.
FAQ
Can the USV follow autonomous routes?
The listed steering system supports autonomous/manual switching. The exact navigation functions and control hardware are defined in the selected system package.
Is the sensor package included?
Sensor selection is project-specific. The vessel can be configured around survey sonar, water-quality instruments, cameras or other compatible equipment after payload and interface review.
Is range or endurance fixed?
No. Endurance and communications range depend on battery capacity, operating speed, payload, sea state and the selected data-link system. These values must be confirmed in the quotation.
