Waterway-AssistWaterway-Assist shows VHF channels, bridges, locks, and chart-based routing for European inland waterways — built and maintained by one person, as a hobby project.
Spot something missing or wrong on the map? Tap the + button, pick Lock / Bridge / Port, and report it — it shows up for everyone right away, no account needed.
Got a feature idea, found a bug, or just want to say hi? Head to 💬 Community — that's the place for it.
Read this before you rely on it: general guidance from common national and ITU allocations, not an official Notice to Mariners. Confirm against current charts or the relevant authority before transit.
Shown to everyone using this planner — don't include personal information. A pin stays unverified until a second, independent report near the same spot agrees — then it's community-confirmed. Neither status is an official source.
📢 Missing a bridge, lock, or channel? Use the + button on the map to report it directly — it shows up for everyone right away. Use this space instead for general discussion, bugs, or feature ideas.
Where this data comes from: locks, bridges and ports are curated from official publications — Rijkswaterstaat / Vaarweginformatie (NL), Port of Rotterdam VTS procedures, Port of Antwerp-Bruges VHF documentation, the CCR's Handbuch Binnenschifffahrtsfunk (Rhine/Moselle), and Kiel Canal transit guidance. Entries are marked confirmed only when sourced directly from one of these.
EuRIS: the EU's River Information Services platform (eurisportal.eu) publishes a broader open RIS Index covering locks, bridges and berths across 13 countries. Its API requires a registered key, which isn't safe to call directly from a browser-only app — integrating it properly needs a small backend to hold the key. That's a planned next step, not yet wired in.
Route line accuracy: the drawn route threads through every mapped lock, bridge and VTS point on the way — it is not a true chart-based (ECDIS/IENC) route. Stretches with no mapped points in between still draw as a straight or lightly-approximated line, not the actual river course. A chart-accurate route would need either a licensed IENC dataset or EuRIS's digital waterway network via a backend — neither is realistic inside a browser-only app.
Coverage: a sample corridor (Benelux–Rhine, Kiel Canal, a handful of major ports) — not exhaustive. Community reports fill gaps between updates.
