It’s already possible to have smart decision support on the bridge: With Furuno’s technology, live video imagery of the front view from the vessel has navigation information superimposed on it including heading, AIS data, radar target tracking, object identification, route waypoint and chart information.SEA.AI’s bridge support system can identify larger vessels not fitted with AIS up to a range of 7.5 kilometers (nearly five miles), smaller vessels up to 3 kilometers (nearly 2 miles) away and flotsam up to 700 meters (nearly half a mile) away.Augmenting a watchkeeper’s situational awareness with technology can reduce fatigue and help them make better decisions, earlier.
