Nautical Ninja
Active navigation for sailors underway
A navigation suite for sailors at sea, all on one screen. It shows live AIS vessel traffic, works out dead reckoning positions, sounds an anchor watch alarm if you drift, and marks a man-overboard position the moment you tap it. Your trip logs itself while you sail, and routes are drawn on official NOAA vector charts.
Live vessel positions, names, speed, and heading from AIS broadcasts.
Draw waypoint routes on NOAA charts with distance and bearing readouts.
Set a radius alarm. It wakes you if the boat drags.
One tap marks a man-overboard position with heading and distance back.
Automatic logging of track, distance, speed, and elapsed time.
Official US vector charts, always current and rendered at full detail.
Plan your route, check for traffic in the channel, and review any hazards along the way.
Monitor AIS traffic and track your course made good while the passage logs itself.
Set the anchor watch alarm and sleep knowing you'll be woken if the boat drags.
Tap MOB straight away. The app locks the position and gives you a heading back to it.
