I did some market surveys a couple of years back and was shocked to find what a distorted view I had about the popularity of Cats. Its very easy to get a distorted view of the beachcat situation from this forum or from sailing in a catamaran dominated club.
I have personally never seen an F16, or an A cat. My club is almost exclusively Hobie 16 with a couple of Tigers. Perhaps they don't really exist and are just the result of some internet hoaxer with photoshop like Bigfoot or Nessie.
But seriously when you compare them to jetski's or dinghy's they are an endangered species. A pretty everage new plastic dinghy will sell 500 a year no problem. I wish we could point to a single cat that could get anywhere near that.
