A cat sailing in Zurich lake?

Hello
i want to know if there is some A cat sailing in Zurich lake?

I will move from France to Zurich soon and I am very interested in the A cat.
I see that the swiss class is active and maybe will join you next year for regatta

I'm looking for a boat and need some advices about different boats available on the 2nd hand market.

With a budget approx. 13000 CHF what about scheurer G5 vs BIM V1R or Geltek Flyer in terms of performance and longevity?

Thanks for your support
