Find a difficult passage again
See at a glance where your boat has already passed comfortably through a narrow entrance, shallow area, or complex inland section.
Your proven passages on a clean chart
Every good journey makes your chart better.
Instead of a tangle of more and more individual lines, see one clear corridor made from passages you trust for your boat. Your own journeys and Tracks from experienced friends automatically grow into your personal safe channel.
No more line clutter
Many journeys become one understandable passage.
When you cruise an area repeatedly, you quickly collect many similar Tracks. Rivers & Seas does not merely stack them. It combines the ones marked safe to navigate into a calm, readable area.
Benefit from experienced friends
Mark a received Track as safe to navigate. The proven passage joins your corridor without adding another distracting line to the chart.
More complete after every journey
Additional trusted journeys add missing sections and alternatives. Over time, they create your personal chart of proven passages.
Coastal and inland
A corridor stays readable long after individual Tracks would become clutter.
In winding lagoons, narrow entrances, and difficult junctions, the number of past journeys does not matter. What matters is recognising the proven passage immediately.
You decide what you trust
Only consciously trusted Tracks become part of the corridor.
Open your own or an imported Track and turn on “Safe to navigate” when you trust that passage for your boat. Rivers & Seas combines all selected Tracks automatically and updates the corridor whenever another is added.
You can hide individual Tracks from the chart. Their combined corridor remains as a clean overview of your proven passages.
A personal channel across your larger screens
From planning on Mac to the Apple Watch at the helm.
The corridor belongs to your Rivers & Seas collection. See your proven passages on iPhone, iPad, and Mac, while Apple Watch keeps the passage visible underway.
Prepare at home
Review a received Track on the larger Mac or iPad screen and add it to your personal channel with one switch.
Orient yourself immediately
A broad corridor is easier to read than many thin, nearly identical lines and stays understandable on a moving boat.
Receive a clean passage
A proven Track from a friend can add exactly the passage that was missing in an unfamiliar area.
Proven means selected by you
The corridor shows experience. Current conditions still decide.
- “Safe to navigate” is your own assessment for your boat or your trust in the source of a Track.
- Water levels, silting, works, closures, and traffic may have changed since an earlier journey.
- Continue to check the chart, depth, current notices, weather, and the actual situation around you.
Questions about safe boating corridors
What is an automatic safe boating corridor?
Rivers & Seas automatically combines Tracks you marked safe to navigate into one shared area. You see proven passages without having to show and hide many individual Track lines.
Does the navigation corridor improve with every journey?
Yes. Each additional Track marked safe to navigate can add to the existing corridor. Matching courses are merged, while new alternatives and missing sections expand your personal chart of proven passages.
Can I use a Track from a friend as a safe passage?
Yes. Import the Track and mark it safe to navigate when you trust the source and its suitability for your boat. It then becomes part of your personal corridor.
Do I have to display every individual Track on the chart?
No. Individual Tracks can remain hidden. Rivers & Seas continues to show their combined corridor as one clean passage.
Does the corridor guarantee that a passage is safe today?
No. It shows Tracks you selected as proven for your boat. You must still consider current water levels, depths, silting, closures, weather, and traffic.
