The app includes a virtual regatta mode where it tries to reproduce the calculation methods used in these regattas.
To switch to virtual regatta mode, go to the Settings menu. In the Virtual Regatta section :
- check the Virtual regatta mode. The app will automatically adjust some parameters to be as close as possible to the game.
- Update the polars. These polar are copied from our servers. If you do not find the polar for a race, send us an email with the Contact us menu. We will do our best to add it quickly.
Once in virtual regatta mode:
- Create your route as usual,
- Download a grib file. The only offered model is the gfs_vr_100 we try to reproduce the model used for the regatta.
The model is updated every 6 hours when data from the GFS model are ready:- 3:35 GMT, 9:35 GMT, 3:35 p.m. GMT and 9:35 p.m. GMT for the 24 hour forecasts
- 3:45 GMT, 9:45 GMT, 3:45 p.m. GMT and 9:45 p.m. GMT for the 48 hour forecasts
- 5:00 GMT, 11:00 GMT, 5:00 p.m. GMT and 11.00 p.m. GMT for forecasts up to 16 days.
If you do not download the grib file, the application will offer you to do it at the launch of the routing.
- Adjust your routing parameters
- Route: You need to edit the first waypoint of your route at each routing to adjust your starting position to your boat position in the game.
- Start date and time: this is the date and time start of the routing in local time
- Routing max days: If you want, for example, to simply make a 1 day routing with a 4 day grib file
- Grib time offset : do not check
- Race start : check if it is the start of the race. This is to avoid initial penalties.
- Polar: choose the one corresponding to the race. These are actually multi-sails polars. The app will automatically choose the fastest one at each point of calculation.
- Pro sails: If you have subscribed to this option
- Current sail : the boat current sail. For potential penalties calculations.
- Foils, Polish, Pro winches : if your boat has these options.
- Minimum wind speed : if it has been set for that race.
- Polar efficiency : by default, do not modify.
- Auto parameters: I suggest you start by using the app in Automatic mode …
- Calculation method:
- Fast: to make a fast routing calculation that might not be very precise
- Standard: the most used.
- Precise: to use 10minutes time steps and a large number of calculated points for the next 12 hours. This is the mode to use if you have a powerful device and you want to take advantage of all the features of the app.
- Land avoidance: check it unless you are in the middle of the ocean and you want to speed up the calculation
- Shoreline: in general in auto mode.
- No go zones: Prohibits routing in these zones. The 60_south_east, 60_south_west, 55_south_east and 55_south_west zones are included in the app for around the world races.
- Grib time offset: probably not useful here.
- Penalties
- tack: check and leave the default values, 50% for 2 minutes
- sail change: check and leave the default values, 50% for 2 minutes
- Allow tacking inside isochrone: in general, leave this option checked
Everything is set, you can start routing.
Wind shift isochrones are displayed in red and you can run pivot routings on these isochrones.
The color of track segments corresponds to the sail used for that segment
Enjoy racing!
