About Dalbi

Dalbi puts the Gelbe Welle on your phone: 543 moorings carrying Germany's DTV Gelbe-Welle quality mark, 420 additional researched moorings, and 139 boat fuel stations — 1,102 stations in total — on a map that works without a signal. THE GELBE WELLE Requestable from the DTV since 2004, the Gelbe Welle is a trusted seal of quality for visitor-friendly stations on Germany's waterways. Previously only published as a PDF. Dalbi turns it into a searchable, offline-first map and adds further researched moorings on top. WHAT'S IN IT • 1,102 moorings across 16 German states — 543 with the DTV Gelbe Welle mark • 5 station types: marina · town landing · canoe launch · guest berth · waterway rest stop • 139 boat fuel stations with fuel types and opening hours where known • 125 official inland-waterway visual and sound signals • Tappable nautical chart with 92,293 OpenSeaMap symbols (buoys, lights, locks, bridges, hazards, boat ramps, notice boards) — 5,183 named and searchable • Harbour dining: restaurants and cafés within walking distance, right in the station view • Routing over the waterway network for canoe and motorboat — computed on your device • Full-text search by name, region or waterway • Filter by station type or federal state • Bright map (warm parchment) or satellite view, optional nautical overlay (OpenSeaMap) FREE TO USE The map, all 1,102 stations, search and filters, three favourites and the full offline mode stay free for good — no account, no ads. DALBI PRO Free for 7 days. Pro unlocks routing for canoe and motorboat with live navigation, plus full station details, every visual signal, unlimited favourites, and satellite + nautical charts. Routing tells motor-navigable stretches apart from small paddle-only rivers; for motorboats you can enter your draft and read the waterway class of the stretch you follow. OFFLINE — BECAUSE IT MATTERS On the water, the network often drops after the first lock. Dalbi loads station data, the waterway graph and the base map on first launch — after that the app works fully offline. On the Mecklenburg Lakes, the Upper Rhine or off Heligoland. WHAT'S NOT IN IT • No account, no sign-in • No advertising, no location-history tracking • No backend — all data ships with the app, routes are computed on your device DATA SOURCES • Stations: DTV Gelbe Welle directory, OpenStreetMap (ODbL), Wikidata, operator submissions • Waterway network: Bundeswasserstraßennetz, GeoBasis-DE/WSV (dl-de/by-2-0), extended with OpenStreetMap • Map tiles: OpenFreeMap (base), OpenSeaMap (nautical overlay), Esri (satellite) INDEPENDENT Dalbi is a project by Driftland Works with no business relationship to the DTV or the Gelbe Welle trademark. We refer to the official directory nominatively under § 23 MarkenG (German trade mark act).

What’s new

Version 2.57.2 · Updated September 17, 2026

New in this version: • Key navigation marks stay visible — hazards, channel buoys and prohibition and mandatory boards no longer drop off the chart as you zoom out. Buoys now show their official OpenSeaMap shapes, and kilometre boards show their river kilometre. • A calmer chart — symbols appear more evenly as you zoom and overlap less. • Dalbi Pro always in Settings — prices, the free trial and purchase restore in one fixed place. • Tappable nautical chart — 92,293 OpenSeaMap chart symbols (buoys, lights, locks, bridges, hazards, boat ramps and notice boards), bundled offline. 5,183 carry a name and are searchable, straight from the map too; every symbol opens its detail on tap. • Real WSV notice marks on the map — inland-waterway signs drawn with their correct symbols instead of generic dots. • Harbour dining at the mooring — restaurants and cafés within walking distance right in the station view, one tap to Google Maps. • More reliable in-app purchases plus many small improvements.
