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
