It has reasonable performance, although a slightly checkered accident history - mostly relared to the undercarriage and it being a taildragger.
I did some initial investigations, there has been some structural verification work done to get it accepted in Australia, however the factory were completely indifferent to helping with UK acceptance and so it looks like it would be pretty expensive......
Elsewhere with the 914 and the lighter options it does look like a reasonable alternative. Having said that it has a wide shallow hull so it will be pretty sensitive to water conditions - flat clam and nothing much more I suspect. But anything small is fairly sensitive so I would not think this is especially limiting.
