Hi David,
The weather chart shown in the Vendée Globe website is apparently provided by Marine Weather Intelligence MWI
https://marine-weather.com/
This brand new company has been launched by 2 persons, one of them, Christian Dumard, is very well known in France as a routing specialist and a marine meteorologist. In addition he used to provide training on the use of Windy for sailing.
Here is an article from Ouest-France newspaper, explaining how MWI plans to base their technology (translated from French):
“ The MWI Yachting app will be based on the Windy weather forecasting tool, to which routing sheets will be added. "We want it to be as intuitive, fluid and educational as possible," says Basile Rochut, co-founder of the company in Auray. Depending on its analyses and needs, Marine Weather Intelligence will be able to communicate more easily with its customers via a chat. The app will be accessible on the web and will be a paid service. Prices will depend on the services used.”
Did MWI get an agreement with Windy via the API ?
That would explain why wind and waves color scale and particles animation on the Vendée Globe cartography is very similar to Windy design.

What model is used ?
Finally the Vendée Globe organisation does not want to share its data (the position of boats for tracking) with Windy, but Windy shares its weather data with it !
