qtVlm
Navigation and weather-routing application for passage planning with GRIB files on desktop and mobile.
Alternative to Navionics
About
qtVlm is navigation and weather-routing software from Meltemus. You load GRIB weather files, plan a route, and compare passages against wind, current, and boat polars. It is used by sailors and small-craft navigators who want routing on the machine in front of them rather than a shore-side advisory service.
A free edition covers core plotting and routing; paid upgrades add further weather and chart features. It runs on desktop and mobile, and it overlaps OpenCPN on chart plotting and PredictWind on weather routing, without being a commercial-shipping optimization platform.
