Boreas Marine Map

Boreas is an offline-first nautical chart and cruising companion. Built for boaters, sailors and fishermen: even with no signal, your chart, your route and your safety alerts stay with you.

87 regions in 23 countries, from the Norwegian fjords to the Florida Keys.

• OFFLINE CHART AND SAFETY
Downloaded regions work with no internet at all: coastline, depths, spot soundings, seamarks, and shallow-water and rock alerts in your pocket.

• CHARTS FROM THE AUTHORITIES THEMSELVES
Where a country publishes its own chart data, that is what you get. NOAA ENC in the United States, Kystverket in Norway, Vaylavirasto in Finland, EMODnet surveyed bathymetry across Europe. Lights carry their real characters.

• YOUR FIRST REGION IS FREE
Download one region, your own water, at no charge. See the depths and the marks before you decide whether Boreas is worth paying for.

• PLAN BEFORE YOU CAST OFF
Pre-departure check: weather, wind and sea state at your departure point, plus a shallow and hazard scan along your route. Automatic routing keeps to water with a depth margin, in every region you have.

• WEATHER AND SEA STATE
Wind, waves, currents, temperature and sea level, with up-to-date forecasts.

• FISHING LAYER (NORWAY)
Registered fishing grounds, spawning areas, shrimp fields, lobster reserves, closures and fish farm sites, from the Directorate of Fisheries.

• FLEET (FREE)
See your boat and nearby friendly boats live on the chart, and share your position.

• HAZARDS NOT ON THE CHART
Community notes, derived rock and shallow markers, and AIS vessel traffic.

• 3D COASTAL VIEW (Pro Plus)
See the shore in three dimensions as you approach.
