Thanks for all the quick answers Roger, web forums Rock...
I read some reviews about several new exciting windsurfing products in the online version of Windsurf Magazine. Both the Gemini and some of the other tandem boards available. here is a link to it for some that don't subscribe to the email.
Gemini Board review:
I am planning our regatta here for April, I hope to have my own tandem Gemini and perhaps being able to get a second one here for the event so that we can do some "team paralell racing". Hopefully a new and exciting racing format...
I will post more details about the regatta as plans are finalized.
