Maritime Navigation Warning Centre
Live NAVAREA and coastal navigational warnings from authoritative sources. Monitor active alerts, explore regional messages, and access the interactive map.
On the map: Noon, every vessel report in one place
Drop any vessel file on the map (a voyage log, ship particulars, a noon report in Excel, a route) and SeaLagom reads it, works out speed, distance to go, ETA, fuel on board and slip, and checks every figure. Write noon reports in your own Excel layout, AMVER, SISTRAM, UKMTO and other standard reports, and compare your fleet.
Warning & coordinate exports
Export NAVAREA and coastal warnings for GIS, planning tools, and bridge ECDIS. TXT is free for everyone; Contributor unlocks ECDIS and KML with full geometry (circles, areas, sectors). Verified on Furuno FMD (incl. FMD-3005), TRANSAS .aiz, and JRC JAN-9201/7201 CSV. JRC .uch/.uchm exports are in beta. Full API adds structured geometry in GeoJSON, CSV, Shapefile, WKT, and related GIS formats.
