The Boating Division did a study and had all the stats. I don't have them handy but I'll see if I can find them.

UPDATE - got this from Boating Division - They surveyed and found 110 boats over 26 feet on Candlewood. They are figuring no more than 150 will probably end up being grandfathered. Apparently they missed a few when they did the survey. No info as to the percentage that were owned by lake residents vs non-residents.
