Hi phill
The M2 class is mostly raced on the lake of geneva, but some of them are also located at the lake of neuchatel.
I heard that Ventilo sells the M2 for around 100k CHF. I don't know if sails are included or not. That is actually not that mutch money. The M2 is sailed by 3, if everyone pays a share...
The Ventilo shipyard is near Lausanne, so you will find them there.
