Your sailing blog. Your wake.
Every crew gets their own ship's log: stories, boat, crew, voyages. Passages arrive from the Rubberduck app, via GPX — or simply told.

What remains when you've sailed
Every passage leaves a trace: the track, the numbers, the story. Kielwasser collects them — as a report with a real chart, as a voyage journal, as a complete sailing blog. Distance, duration and route are computed from your track automatically.
Your log belongs to you
Your own space, your own photos, your own readers. Ad-free, no data trading. GPS data in photos is stripped automatically, positions are shown with delay only — and everything can be exported at any time.
A community of ship's logs
The platform grows between the logs: cruising areas to browse, voyages to follow, real experiences from real crews — from weekend hops to bluewater passages.

How your log comes together
🦆 From the app
Finish your passage in Rubberduck → "Publish to Kielwasser". Chart, numbers and log arrive by themselves.
📈 Via GPX
Upload a track from your plotter or any app — Kielwasser turns it into chart and statistics.
✍️ Simply told
No track? No problem. Words and photos are enough — good stories don't need curves.
