The Dookyu Crown 22ft Electric Harbour Inspection USV is a 6.6m aluminium unmanned surface vessel designed around quiet electric propulsion and autonomous/manual control. Its intended role is short-range harbour inspection, environmental response support and remote observation in sheltered waters.
This page is separated from our survey-focused USV configuration so buyers can evaluate the vessel by operational purpose. Patrol cameras, warning equipment, communications links and rescue or monitoring modules are selected for the project; they are not assumed as standard equipment.
Quiet electric drive: the listed X-12 12kW E-propulsion system is suitable for operations where noise and local exhaust at the point of use need to be reduced.
Autonomous/manual switching: routine inspection routes can be combined with direct operator control when approaching vessels, quay structures or incident areas.
Compact aluminium platform: a 6.6m overall length and 2.2m beam provide a practical base for cameras, environmental instruments or light support equipment selected for the mission.
Remote task support: unmanned operation can reduce personnel exposure during preliminary inspection of restricted or potentially hazardous areas.

Harbour perimeter inspection: camera-based observation around berths, breakwaters and restricted areas.
Environmental incident support: carrying project-specified sensors for preliminary observation or water measurements near a reported event.
Infrastructure checks: remote viewing around bridge piers, quay walls, intake areas and floating assets.
Emergency reconnaissance: first-look observation before a crewed vessel enters an uncertain area; this is a support role, not a certified rescue function.
Camera type, communications distance, autonomous functions, battery endurance and payload capacity vary with the selected equipment and operating profile. No fixed claim is made here for range, obstacle avoidance, stealth performance or mission endurance. Those values belong in the signed technical specification after system selection and testing.
Send the operating area, maximum distance from the control point, required video or sensor feeds, expected mission duration, payload list and charging conditions. We will then define the control system, battery arrangement, communications architecture and deck interfaces around that duty.
Can it be used as a crewed passenger boat?
This page describes an unmanned inspection configuration. Any crewed use, passenger capacity and applicable certification must be reviewed separately for the intended market.
Does electric propulsion mean zero lifecycle emissions?
The vessel has no local exhaust while operating on battery power. Total lifecycle emissions depend on electricity generation, battery production and the operating profile.
Are cameras and communications equipment standard?
No. They are selected according to the required observation range, image quality, data bandwidth and local network conditions.
