⚓ Support Kielwasser

Kielwasser runs on donations — not on ads.

Kielwasser is an ad-free labour of love: every crew keeps its own logbook, and official waterway notices, lock times and marine weather from many countries come together here. That costs servers, data access and translation — but no ads, no data selling. If Kielwasser helps you, drop a little something into the ship’s fund.
