Hi, i'm a member of charal sailing team and i Join Damien's question, i think most of the offshore racing skippers (especially for the next Vendée Globe) would be very interested to see their boat current position on the map. today windy is mostly used to prepare the races but not so much during racing, if it is an interest for you that windy become a tool used onboard, it would be interesting to work on containing the amount a data downloaded as we used satellitar internet supplier and to be able to place the boat realtime on the map.
cheers
Nicolas
