Interesting topic.
Having this demographic info readily available, and perpetually current could mean increased access for kiting, SUP, and other watersports we love.
Since part of the ASF mission is to help preserve and to INCREASE access (throughout the USA), we put a lot of time into finding the right tools and combination of components to obtain an "industry survey" such as this.
Providing we had this info on hand for these watersports, it could be used to seek increased access to public lands, to seek donated land, or even seek state/ federally owned lands specifically for watersport activities. Tampa Bay Watch, just outside Ft. Desoto Park, is a prime example of the state donating a 600,000 dollar chunk of waterfront land to a charitable org., or Shake-A-Leg in Miami would be a good example for the South Fla readers.
For kiteboarding, we have the upcoming
2010 Kiteboarder Census, which will be readily available to affiliated local kiting associations working to preserve access. More on this soon.
This will easily work for a SUP survey also, we just need the survey questions and help circulating it. Let me know if anyone would like to tackle a project like this.
Happy Paddling!
