Latest release
What’s New
Boreas no longer guesses where your voyage starts. Ask for a route while ashore and it asks where the boat is leaving from, offering the berths on the chart around you - and it remembers your answer. The weather no longer says you are offline when you are not. If the forecast cannot be fetched, Boreas says why, shows how old the reading is, and lets you try again.
