The McQ SonoWatch® is an advanced maritime acoustic sensor designed to serve as an autonomous lookout system for safe vessel operation. Built specifically for unmanned surface vessels (USVs) and other maritime platforms, SonoWatch® detects and interprets navigation signals to enhance situational awareness in challenging conditions.
At its core, SonoWatch® features a 360° acoustic array ruggedized for harsh maritime environments. Combined with an onboard industrial computer, the system processes acoustic data in real time and provides timely alerts of navigation warnings. This ensures compliance with international “lookout” rules, helping crews and autonomous vessels avoid collisions and operate safely in busy waterways.
Why Acoustic Sensors Matter in Maritime Safety
Acoustic signaling has long been a critical element of maritime navigation. In low-visibility conditions such as fog, heavy rain, or night operations, vessels rely on acoustic signals—like horns and whistles—to coordinate maneuvers and avoid dangerous situations. The U.S. Coast Guard’s COMDTINST M16672.2D specifically mandates that vessels maintain a proper lookout by sight, hearing, and other means necessary to assess collision risks.
The SonoWatch® maritime acoustic sensor directly addresses this requirement by serving as a reliable “hearing system” for vessels. Whether on a manned ship or an unmanned vessel, it ensures acoustic signals are detected, classified, and acted upon in real time—strengthening overall maritime safety and compliance.
