Map and nautical charts
Every map in the app shows the same vector map, from the first start, even without an account and without a Hub. This base map is not a nautical chart: it contains no aids to navigation, depth figures or fairways. On it you see your boat with course line and track, your berths from the logbook, on sailing boats your tacks and gybes, other vessels via AIS and the boats of your Boat Buddies. If you tap a point, the map shows distance, coordinates and bearing to it. If the point is close to the boat, you set the anchor watch directly from there. With the Standard subscription you also get the official nautical charts of the BSH for Germany and of NOAA for the USA, with aids to navigation and further maritime information. More areas are in preparation and will be added with one of the next updates.
What you get
On board
- Base map and nautical charts: Without a subscription the map shows land, coast and water, but no aids to navigation, depth figures or fairways. With the Standard subscription every map in the app also shows the official nautical charts of the BSH for Germany and of NOAA for the USA with aids to navigation and further maritime information, on board and remotely, and with offline maps also without internet.
- Your boat: An arrow shows your heading, a thin line your course over ground to the edge of the screen. Plus your track in the selected period as a continuous line. If no new position arrives for a few seconds, your boat symbol fades.
- Map layers that you switch on and off individually:
| Layer in the app | What it shows |
|---|---|
| Anchored, Docked, Moored | your berths in the selected period |
| My stops | your berths from the rest of the history, that is everywhere you have been |
| Maneuver (sailing boats) | your tacks and gybes in the selected period; tapping opens the manoeuvre analysis |
| Other vessels | AIS vessels, see AIS |
| AIS Aids to navigation | Buoys, beacons and lights via AIS |
- Your Boat Buddies’ boats live on every map, including on your Plotter during your own trip. You recognise them at once: zoomed out they appear with a boat photo, closer in with a Boat Buddy symbol of their own, always with a name. This also applies if their position comes via AIS: the app recognises them by their MMSI and does not show them as an ordinary AIS target. Tapping shows photo, name, status line, when the last position arrived, distance to you, speed, course, heading, coordinates, supply voltage, the owner’s name and MMSI. See Boat Buddies.
- Tapping a point: A small sheet opens at the bottom with the distance from your boat, for example “320 m away” or “1.4 nm away”. If the point is on your track, the time you were there is shown with it. Pulling up shows latitude, longitude, “True Bearing” and “Relative Bearing” (relative to your bow).
- Anchor watch from the map: If the point is at most 100 m from your boat, “Set Anchor Watch” appears directly in the sheet, also on the map in the Alarms screen. The app suggests the radius from the distance, at least 20 m. Then you adjust it between 10 and 100 m. If the anchor watch is already running, it moves to the new point. See Anchor watch.
- At the edge of the map: Scale, coordinates of your position in the chosen format, air pressure tendency (tapping opens the barograph; on narrow maps, for example on a phone in portrait mode, it sits in a second line below the coordinates), base wind as an arrow with strength, compass (tapping aligns to north), centring on your boat (the map then follows you), ruler and map layers.
Remotely
- If you connect the Hub to the cloud, the map in the Dashboard and in boat monitoring shows your boat, the track, your berths, manoeuvres and the anchor watch, plus your own location as a blue dot.
- With the full-screen button in the Dashboard you open the large “Sea Map”, with time range selector and GPX export in the header.
Map basis
- The base map is based on data from OpenStreetMap.
- You find source and copyright notices under Settings › About › “Info”, section “Attribution”: “Map data © OpenStreetMap contributors” opens the OpenStreetMap licence page, “Nautical chart data” shows the notices of the nautical chart producers in their original wording, for example of the BSH, the German Federal Waterways and Shipping Administration and the Hamburg Port Authority.
How it works
Where you find the map: on board in the Plotter (Menu › “Plotter”), under Menu › “Environment”, Menu › “Alarms” and Menu › “Monitor”, remotely in the Dashboard (Menu › “Dashboard”). You open the large “Sea Map” with the full-screen button in the Dashboard.
Choosing map layers
- Tap the layers button at the top right of the map.
- In the “Map overlays” dialog switch the layers you want on or off. Your choice applies to all maps in the app and stays saved.
- At the bottom of the dialog, “Offline Maps” leads to your offline maps.
Setting the anchor watch from the map
- Tap the spot where your anchor lies.
- In the sheet tap “Set Anchor Watch”.
Moving the map
- Pan, zoom, rotate and tilt with the usual gestures. The centre button brings your boat back to the middle.
Requirements
- For the map: internet on first load or previously downloaded offline maps. No account, no Hub, no subscription needed.
- For boat, track, berths, manoeuvres, AIS and anchor watch on board: app connected to the Hub.
- For your Boat Buddies’ boats: signed in and internet on your phone or tablet.
Permissions and subscription
| What | Without a subscription | With the Standard subscription |
|---|---|---|
| Base map (without aids to navigation) | yes, even without an account | yes |
| Official nautical charts (BSH Germany, NOAA USA) | no | yes |
| Boat, track, berths, manoeuvres | yes | yes |
| AIS on board | yes | yes |
- On board: Everyone connected to the Hub sees all layers and sets the anchor watch from the map.
- Remotely: Owner and Boat Buddies see boat, track, berths and manoeuvres; AIS and setting the anchor watch are only available on board.
Safety notice
- Not an approved means of navigation. Map and nautical chart data do not replace official nautical charts and notices to mariners.
- The base map is not a nautical chart. It contains no aids to navigation, depth figures or fairways.
Notifications
None.
Messages and special cases
| Situation | What happens |
|---|---|
| No internet on first start, no offline map | The map area stays empty. Boat, track and AIS from the Hub still appear. |
| No own position | The sheet shows “Position” instead of the distance, without bearing and without “Set Anchor Watch”; at the edge it says “Latitude” and “Longitude”. |
| Point further than 100 m from the boat or a past period | no “Set Anchor Watch” |
| Past period selected | AIS, friends’ boats, coordinates and base wind disappear, the map shows the whole track |
| Period selected in the calendar that includes today | counts as the current period: AIS, friends’ boats, coordinates and base wind stay visible |
| Map loads slowly, for example on a weak network | Boat, track and layers appear as soon as the map has finished loading |
| Signing in or out | The map reloads so that it matches your account |
Offline behaviour
- Without internet the map shows your offline maps and what it last had in memory.
- Everything from the Hub (boat, track, berths, manoeuvres, AIS, anchor watch) works on board without internet.
- Boat Buddies’ boats whose position comes over the internet need internet on your phone or tablet.
- Your map layers are kept across a restart. Section and zoom start at your boat again.

How do I set the anchor watch directly on the map?
Tap the spot where your anchor lies, at most 100 m from your boat, and then tap "Set Anchor Watch" in the sheet.
How do I hide AIS vessels or berths?
Tap the layers button at the top right of the map and switch the layers you want on or off in the "Map overlays" dialog. Your choice applies to all maps in the app.
Do I see my friends' boats on the map?
Yes, the boats you follow appear live on every map, including on your Plotter during your own trip. For this you need internet on your phone or tablet.
