Unmanned boats scanning lake floors in Maine have raised privacy and safety concerns.
Residents of Great Pond in Belgrade and nearby China Lake have spotted small, unmanned watercraft moving silently across the lakes, believed to be using sonar to map lake floors.
The devices, resembling small motorized pontoons with lights, appear to be operated by a Texas-based company under contract for private clients.
Though no malicious intent is suspected, the lack of identifying marks, transparency, and regulation has sparked concern among locals and officials about privacy, boating laws, and public awareness regarding such technology on public waterways.
