I certainly back Hobie1616. Think in terms of a sailing club such as Sarasota Sailing Squadron or Clearwater Community Sailing. Google their sites and see for yourself what has worked. SSS has no liquor license; therefore, there is no entanglement with the feds and city with that issue. That Works for kids!
Dunedin, FL is another example of where a "Waterfront Development Committee" working with the city and state authorities have succeeded. They are now offering after - school, high school sailing in 420s. They began by working with marina owners and businesses to open up access. One of the first physical steps involved adding sidewalks to the waterfront. I believe paddleboard/kayak areas are coming down the road if not recently established.
One of the important valuable resources a group may incorporate is a 501 (c) 3 plan for growing your fleet of boats and other physical resources necessary.
I just donated my 16' boat to their effort so a high school instructor can add sailing to their curriculum. They refitted the craft (new engine and paint) and now she hauls kids back and forth in their 420s to Clearwater for race training.
P mail me, and I can hook you up with a very nice human being that would love to answer any questions you might have.
