Radar and ais alerts you to navigation hazards above the water, but what about those below it? Poorly charted waters and submerged objects can cause your vessel to run aground or have a collision, placing everyone onboard at risk. Install our navigation and obstacle avoidance sonar, and transform your underwater situational awareness.


Human and charting errors are the largest causes of vessel groundings and collisions when navigating. That’s why if you’re transiting routes, even familiar ones, a forward-look sonar can help you see what lies ahead under the water and automatically warn you of hidden dangers.

Our solution, NOAS, has been designed in collaboration with ship’s officers for large vessel types such as passenger ships (including exploration-class cruise liners), naval vessels, research ships, commercial ships (including autonomous ships) and private superyachts.

Using dual sonar transducers installed in the bow of your vessel, NOAS works by scanning the water column at a navigationally significant range ahead of the vessel in order to generate a 3D model of the seabed. The model is displayed relative to the vessel and overlaid on nautical charts in real-time, providing your crew with an easy to interpret image of the underwater topography the vessel is passing through.

Alerts can be configured to warn of potential collision hazards or shallow water. These can be based on depth, distance from the vessel and estimated time to impact. Multiple alerts can be programmed and are displayed in the profile view and depth scale. Uniquely, NOAS also offers an intruder detection capability to warn of divers approaching your vessel when it’s stationary. NOAS is designed to be retro-fitted to existing vessels as well as new vessels and comes with comprehensive engineering support and advice to ensure installation, commissioning and crew training is trouble-free.
