Real Time Weather NavData

In addition to weather forecasts (that are derived from numerical weather model), TZ iBoat also can display real time weather data and tendency that is collected from observation stations (METAR stations). This real time weather information can be displayed in a NavData. TZ iBoat will always display the closest observation station from your own ship position:
