VRTool vs KWINDOO RaceCommittee

VRTool is a sailing planner and calculator. Calculators combine the following data: - GPS position ( or DR position ) - Polar chart customized for your boat ( your boat performance charts ) - 144h wind forecasts from NOAA GFS. - High resolution GSHHS world maps Real time sailing monitor shows the polar point, TWA, sail efficiency, best course, great circle distance and course to destination. Also logs boat positions, saving boat parameters periodically. Charting tools include: measure tool, route and track design, fixed wind angle tracks, marks, geodesic circles. Weather routing calculation up to 144h, with land collision detection. This finds the optimized route to destination considering the wind forecasts and performance of the boat. Wind forecasts from NOAA GFS, via VRTool webserver. Interactive Polar Chart Editor, for customizing your boat polar charts. VRTool can be configured to act as a NMEA talker, broadcasting GPS messages to other software connected to the boat local network ( including VRTool desktop edition)

Kwindoo Race Committee is for regatta administrators and organisers using KWINDOO services for their sailing regattas. Use Kwindoo Buoy Positioner application in conjunction with a KWINDOO organised regatta to finalise previously, provisionally set buoy positions at their final and exact location. In real life take your phone aboard the organiser boat in charge of setting up the waypoints of a race and use the application to reposition the selected provisional buoys in the desired final locations for the race you are building. The revised location settings will be automatically transferred to your regatta as final buoy positions. Continued use of GPS running in the background can dramatically decrease battery life.
