JR,
Thankyou for the info. I'd be interested to know how much these machines weigh. From the specs I would expect there is no min weight. But realistically machines like these would have weight limits imposed by materials and contruction methods and these are both linked to the available budget.

If I can make my way to Europe again I will do my best to get to lake Geneava to see these sailing machines.

When are the Geneve-Rolle-Geneve and the Leman Bol d'Or
regattas usually run?

Regards,
Phill

Phil,

If you take as an example the Ventilo M2, the weight is 375Kg. The first status of the class mention that boat must get a insubmersible certificate... so this creat certainly also a contraint that will imply a certain weight.

Regarding the Regatta: you can find more information on http://www.am2.org

Geneva / Rolle / Geneva will be held on June 10-11 2006
Bol d'Or du Lac Léman will be held on june 17-18 2006 (departure at 09:00 saturday morning)

Regards,
Jr
