This is just a taste. In the app this chart works offline; GPS, a draft-aware shallow-water alarm, anchor watch and a 3D coastal view are added. Basemap: CARTO · Satellite: Sentinel-2 (EOX) · Marks: OpenSeaMap · Depth: EMODnet · Hazards & farms: derived from open sources. Not an official nautical chart.
