VRTool combines a sailing calculator, worldwide charting and GPS data logger. Most of VRTool desktop charting features are now present in this mobile app. Key data components used by VRTool:
- GPS position ( or you can type coordinates, for game usage )
- Boat track
- GSHHS world maps
- Polar chart ( customized for your boat ).
- NOAA GFS wind forecasts.
VRTool shows the current polar curve, TWA, sail efficiency, best course, great circle distance and course to destination. It also logs boat positions, saving boat status periodically.
Charting tools include: measure tool, route and track design, fixed twa track, marks, geodesic circles.
Weather routing brute force calculation up to 144h, with collision detection.
Interactive Polar Editor for customizing your boat polar chart.
Edit sailing points as you sail by dragging the curve to actual data.
It can also be configured to act as a NMEA talker, broadcasting GPS messages to other software connected to the boat local network.
