Wouter,
I support all you say about the need to make sailing cool again, but Hobie 16's have an image that is way cooler than F18's or any other Cat, it is all down to the sail colours, to the average Joe on the beach all cats are alike, except those ones with the cool sails. Why do you think holiday companies use them in thier brochures and TV adverts so much.
Cool is all about image not performance. What makes you think a teenager would think that a spinaker makes a boat look cool? It just makes it look more like their freinds uncles floating caravan.
