My guess is that this is because VRTool has a little bug : it refuses to import boats with null speed (grounded or just stopped), null true-wind-angle nor null wind speed.
When the race is started everything should be all right.
I have another present for VRTool users...
Donwload and uncompress the following file :

Beware, it is based upon the latests race information, but they can be changed by the race organisors for any reason.
This archive contains 1 VRTool desktop file, 2 maps (low and medium resolution), 4 polar files (pro/standard, classical/full) and every necessary MP coastlines.
The desktop is configured with the low definition map. To change it, don't use VRTool menu, you'd lose the coastlines, better edit the file with Windows notepad or so, (Start Menu, Programs, Accessories, Notepad) and change the line

Eventually, you will also have to indicate the full file path,
eg : O;Chart;C:\My Data\Documents\VRTool\CapIstanbul\c_gshhs_i.cht; 38.10170; -17.45310; 23.84141
Choose the polar file that suits you the best.
And have a good race.
