From an MNA perspective this works too.
Transfer your coach boats and coaches from Kiel to Sopot and then have your youth athletes take part in the RS:X Youth European Windsurfing Championships which finish in good time to move onto the the Volvo Youth Sailing ISAF World Championships taking place in Istanbul, Turkey on July 8th [finishing July 17th]
Meanwhile those Olympic athletes taking part in the RS:X European Windsurfing Championships which start on July 2nd can rub shoulders with the youth teams at their prize giving before taking part in the senior event. The coach boats should already be there so the logistics planning should be simplified and your costs reduced.
The Notices of Race for these events are now being finalised and will be published asap
