Suggest you go take a look at
www.squamlakes.org/ and
www.squamlakes.org/support/youthactivitybarn.php and see what they got going for a community sailing program!
The Squam Lakes state boat launch is located on the 1/8 mile long Squam River that connects Big and Little Squam, and is about two miles across the water from the sailing program facility pictured in the above websites. That large building (not the new activities barn) in
www.squamlakes.org/ used to be a Rt 3 motel, until about the year 2000 when it and the LAND was purchased by the Squam Lakes Assoc.
