Boat navigation that looks ahead
Set off. Know what is ahead.
As you cruise, Rivers & Seas recognizes your waterway and automatically shows what matters next: bridges, locks, closures, and vessel traffic. You do not need to enter a start or destination in a route planner first. Even with the iPhone or iPad locked, an important alert can still reach you.
For iPhone and iPad—with Apple Watch and onboard data when you want more.
Works in the background
The map can be closed while important alerts appear on your iPhone or iPad.

The difference from a conventional boat route planner
You do not need to build a route to know what lies ahead.
Many boat route planners reveal bridges, locks, and travel times only after you choose a start, destination, and waypoints. Rivers & Seas recognizes the waterway you are actually cruising and automatically brings forward what matters next.
Turn onto another waterway and the look-ahead turns with you.Just set off
No start, destination, or waypoints are required before the app helps you underway.
Your real journey decides
Direction, position, and speed continuously determine which waterway and structures matter ahead.
Arrival, not a line on a map
See when you are likely to reach bridges, locks, closures, and vessels.
A conventional boat route planner is planned as an additional way to prepare a journey—not as a prerequisite for Rivers & Seas to help while you cruise.
Discover automatic boat navigationYou have a Track
Know when to leave before setting off.
Rivers & Seas checks the Track against cruising speed, lock duration, lock opening times, and gauge or tide predictions. You can see when to set off so the important places along the journey work together.
Reach locks in time
Expected arrival is compared with available opening times, with earlier lockages already included for later places.
Check clearance at arrival
Gauge level or tide and your boat height determine whether the passage is expected to fit.
One recommendation for the journey
Several calculable places are combined into one departure window.
Try the map and AIS for yourself
See your waters—and the vessels on them.
Move around the real Rivers & Seas map and discover available AIS targets directly on the water. Use the round map button to switch between the bright map, automatic day-and-night map, Seascape with water depths, and satellite imagery. OpenSeaMap navigation marks remain visible.
Tap a place to mark it and share it as a link.
Set off without checking everything first
The warning comes to you—even with the map closed.
This is look-ahead navigation that genuinely takes work off your hands. Set off spontaneously, pocket the iPhone, and Rivers & Seas looks along the waterway in the background. Before you reach a closed lock or a bridge that will not fit, the important message can already be on your Lock Screen.
Lock closed
Know early when a closure or opening time means that the lock will not be available when you arrive.
Bridge too low
A known insufficient clearance can appear as a clear alert on the Lock Screen of an iPhone or iPad.
Large vessel approaching
Relevant oncoming AIS traffic can reach you while the phone stays in your pocket.
Catch the same lockage
When the timing fits, the alert can show the speed for arriving with a vessel ahead.
Waterway ahead
No start, no destination. The app still looks ahead.
While you cruise, Rivers & Seas recognizes the waterway and automatically puts the next bridges, locks, notices, and vessels in the right order. The view keeps updating with your position, direction, and speed.
Bridges
See the crossing ahead early, with a photo and the available clearance at your arrival where data allows.
Locks
Opening times, closures, VHF, and telephone details appear before you reach them.
Vessel traffic
Understand commercial traffic, ferries, and oncoming vessels in the context of the waterway.
Not at some point. At your arrival.
The information fits the moment when you need it.
A static bridge height or opening time tells only half the story. Rivers & Seas relates your boat, current speed, gauge levels and tides, and available notices to the journey ahead, then explains what that means in plain language.
Will the boat fit?
Warnings use your saved boat dimensions and, where available, the expected water level at arrival.
Will the lock be open?
Operating times and closures are interpreted for your estimated arrival.
Should you call now?
VHF and telephone details are ready before the bridge or lock needs your full attention.
A commercial vessel ahead could save a lock cycle
See the speed needed to arrive for the same lockage.
Rivers & Seas compares the commercial vessel’s arrival with your own. At the lock, you see the vessel, contact details, and the speed that would bring you there together.

What is coming around the bend?
Rivers & Seas brings online AIS and vessels from your own receiver together on one map. On known waterways, it becomes more than a field of targets: you can understand oncoming traffic, a crossing ferry, or a large vessel ahead in time.

Inland and coastal in one app

Along the coast, satellite imagery, OpenSeaMap marks, and depth shading work together. Inland, bridges, locks, notices, and traffic ahead take centre stage. Your places and boat data stay with you everywhere.
