Following are suggested settings to get started in Virtual Ragatta's Volvo Ocean Race Game 2014.

Vector Charts

Menu: File/Open Vector Chart...

• Open the main vector chart file c_gshhs_i.cht.

Menu: File/Merge Vector Chart...

• Merge each of the localised pixel sub-charts onto the main chart to overlay the Virtual Regatta coastlines on to the display.

The main chart and the VR pixel sub-charts for each leg are posted in a ZIP file on the Volvo Ocean Race page of the Virtual Regatta forums. Put all the chart files in the same folder as your .nav file before loading/merging them.

Collision Detection

NOAA import grib file

Download params

• Time zone: Click on the to set to your PC's time zone
  
• Resolution: 12
• Up to: 180 for normal forecasts, 384 for long-range forecasts
• Accept incomplete downloads

Transformations

• game windspeeds (rounded)
• Grid probe resolution: 1.0

Weather Routing

Routing

• Isochrone interval: 0.5 for tracks up to 1000 nm, 1.0 for long tracks
• Up to isochrone: 0
• Show isochrones: 1h

Config

• # of tree branches: 181 (if you are using a "full" polar)
• Max angle to destination: 90
• Boat wake angle: 30
• Iso point spacing: 1%
• Land collision detection
• Add branches at isochrone points
• Use new pruning method

Winds Tab

Wind grids

• overwrite previous wind grid (optional, but avoids confusion)

Polars database

• Simple polars: vor0_pro-full.csv (available from vrtoutoulz.fr)

Selected

• Simple polars

• Boat spd factor: 1
• Interpolate windspeeds

Wind interpolation

• Interpolate winds

In time

• previous

In position

• bilinear

• use U/V interpolation for TWD

Boats Tab

Boat Data

• GetUser: Enter the unique GetUser string for your boat in this control. This string has the format:

http:/vvor.virtualregatta.com/core/Service/ServiceCaller.php?service=GetUser&id_user=......

• Auto update in (if you want you boat track(s) to update automatically)

Other Tab

Track Designer Settings

Wind forecast age

• windgrid timestamp + a time zone. Keep this option selected unless you are doing two-step routing or laying a track from an advanced position.

Wind grid timestamp

• Time zone: Click on to set his field to your PC's time zone setting. While Paris is on CET time (European winter) adjust this setting one hour to the west (subtract one hour).

• Integration time step: 1 minute
• Line snap mode: integer courses
• Track marks frequency: 1h
• Use Fixed TWA - if you want the track tool to draw fixed wind angle tracks.
