The boating map where everything comes together
OpenSeaMap—and an app that looks ahead while you cruise.
Rivers & Seas combines OpenSeaMap marks, depths, your position, and AIS with Waterway Ahead. Inland, bridges and locks appear automatically; along the coast, depths, navigation marks, and satellite imagery remain close at hand.

The map stays calm. What matters moves forward automatically.
OpenSeaMap supplies the nautical context and OpenStreetMap shows life ashore. Rivers & Seas turns them into a map for cruising, with AIS targets and, on supported waterways, bridges, locks, and notices ahead.
Other vessels in the same view
Available AIS targets sit on the map instead of requiring a separate radar app.
Inland and coastal
Bridges and locks inland, depth shading and satellite imagery at the coast, without changing apps.

Marine depths you can understand at a glance.
For marine and coastal areas, Rivers & Seas also offers a depth-focused map with color-shaded water, depth contours, and spot depths. Shallow areas stand out immediately while sea marks and current boat data remain visible.
The depth view is available for marine and coastal areas. It supports orientation but does not replace official nautical charts or safe navigation.
