Boats come in different shapes. There is the old tradition with its wealth of variation. There is the modern tradition which seems to state that all boats should look more or less alike. And there are a few examples of a mixed breed between the two. But to categorise which kind of tradition a particular design belongs to is not necessarily the decisive factor; rather, the quality of a design is determined by the more or less happy fusion of a number of separate characteristics. In the case of Aileron, the outcome will also depend on a few innovations which have been melted into the design. The transom, the keel flap and the hull shape are all very different. However, it may be interesting to note that a few innovations are in fact old and well-proven ideas which have somehow gone out of fashion..... Thus, we have endeavoured to find a successful combination of past, present and future.
