Lake Thun · Map comparison
Paper map or app on Lake Thun?
On paper, you can see the whole lake at once. In the app, you can see your position and choose the information for your trip. Which helps most depends on how you spend your time on the water.
The everyday differences
| What matters on the water | Paper nautical chart | 150/300 |
|---|---|---|
| Overview | See the lake on one sheet; the scale stays fixed. | Zoom, switch between map and satellite view and enable individual layers. |
| Your position | Work out your position using the shore, landmarks or other aids. | With location permission, see the position determined by your device on the map. |
| Harbours & depths | Depending on the chart, depth information and harbour plans are already included. | Show recorded harbours, visitor berths and depth contours. No live display of vacant berths. |
| Wind & scheduled boats | Check weather forecasts and current timetables separately. | See wind forecasts on a timeline and estimated scheduled-boat positions. Positions are based on the timetable, not AIS. |
| Plan a trip | Plan and mark your course and stops by hand. | Sign in to plan routes with multiple stops and use boat mode. |
| Without signal & power | Readable without internet or a battery. | Download the offline map beforehand. The device needs battery power; weather and new data require internet. |
| Data currency | Check the print date and available corrections; add changes yourself. | Download available data updates. Check the relevant data date in the app too. |
| On board | Allow room to unfold it. For use by the water, choose a suitable waterproof edition. | Use it directly on screen. Check battery, brightness and water protection beforehand. |
What suits your trip?
For the overview: paper
You want to see the whole lake, discuss an outing together or carry an overview that does not rely on your phone.
While out on the water: the app
You want to see your position, find a visitor berth, compare wind conditions or plan a trip with intermediate stops.
For longer days: both
Plan with the app and take paper as an additional overview. Download offline content before setting off and plan a power reserve.
Which paper chart do we mean?
One example is BoatDriver-Map 4 for Lakes Thun and Brienz: the publisher lists depth information and harbour plans at a scale of 1:25’000.

Depth contours show a model of the lakebed, not a measurement beneath your boat. Offline availability depends on content loaded beforehand.
