Berny, why one class "takes off" and another doesn't has always been one of sailing life's "great misteries. We can look back at designs that were highly successful, in all respects ie numbers sold perfomance etc, as say, "yes I can see with hind sight why that worked, similarly we can look back at one that didn't and say the same, BUT there are many, many, many designs of both mono and multi hulls that no one can say why THEY either succeeded or why THEY failed. Success with boats can be simply put - It is and always will be a "black art" that I defy any one to work out definatively
