I think racing is secondary to fun.
1. Build real websites and do a pull campaign. Nacra's is pathetic. Hobie's is average. Neither are well known in comparison to other sport activity websites.
2. Video brochers. Hobie has a couple that don't look exciting. Nacra has none. Excitement and fun in a group is the key. Pander to all age groups, not just people with families. Jeezzz, we build copper bar and can make it look some-what interesting in our catalogs and videos. They can't with a moving boat?
3. Modern dealership model. Take a page out of the automotive industry's playbook. Big, regional dealerships run by the factory in high-traffic areas. New and pre-owned.
Sorry to say it but mom and pop dealers aren't going to get the job done. Limited inventory means no touching. No one will buy into a $6000+ activity sight unseen.
4. Some kind of public relations. Right now if there is a big event, no one knows about it outside of hard-core race sailors. No one will sponsor a big event if there is no production value. Why put a sticker on a boat if no one is there to see it other than contestants? Commercial? Ad campaign? Marketing materials (calendars, junk mail)...
There is a void in cat sailing. I don't see an "image" in it anymore. I swear the first factory to paint a new exciting image, press the flesh a little and get some boats out in public will attract new sailors. Create the market. Jump in bed with other companies. Relate the product to a lifestyle. It is just a void held together by small groups of fleets right now. As the members grow older, the void deepens.
