Cat sailing is fun, but the majority of new boat buyers are buying the Getaway which without some moderate wind isn't super fast. There are 250,000 Hobie 16's sold out there that are slow compared to a lot of modern and some older boats. The speed thing is realtive and really not a huge issue to the majority (which do not race).
Besides, this is a moot point. It doesn't matter if in 10-20 years there are half as many sailors to buy a boat, maybe even less. You have to get younger people with disposible income interested. They watch TV. They read Cosmo and Maxim. They go to clubs/bars.
Face the facts... no matter how "manly" you make sailing, if no one knows about it, they don't care. The only ads I ever see are the back of Murrays and Hobie catalogs. The only video I see is off obscure websites. (Until a typical person on the street knows to go to Hobiecat.com to see sailboats in action, it is obscure).
