In North America it is advertised and sold as just that - an inland lake or protected coastal water hybrid powersailer. This is clearly printed in the brochure. It is not advertised as an off shore blue water boat and I am not aware of any owners that would use it that way. 'Fair Weather Cruiser' suits me just fine because that is the kind of sailor I am. It is a great boat for its' intended purposes.
I do not have a clear understanding of the EU CE classifications, perhaps it is just some little hurdle that has to be circumvented in order to import the boat into EU but does not neccessarily or in reality make the Mac a bonafide class C.
