M_Boats: OT - CNG Question

Bob mentioned converting the '80s era N-27 from CNG. A friend of mine has a Hunter from the same time frame. He can not find CNG. This boat is on the Chesapeake. (He is partners with his corporate jet type brother-in-law who rarely sails - what a deal!) I thought CNG was THE FUEL OF THE FUTURE. What happened? steve Steve R. M-15 #119 Lexington, KY
