    • A Homemade Solution For CNG (Compressed Natural Gas) Aboard

      One thing we are learning loud and clear while putting the Cruisers’ Net’s LPG/CNG Availability Directories together, is that Compressed Natural Gas is available in very, very few places along the coastal waters of the Southeastern United States. And, that’s too bad, as CNG is lighter than air, while LPG (Propane) is heavier, and a leak can potentially pool an explosive quantity of propane on your galley floor or in the bildge. Conversely, a CNG leak is far less serious, as the gas will rise and hopefully dissipate.
      Well, Captain Denise Gill has come up with an innovative to get CNG aboard. It takes some ingenuity, and some work (and money), but Denise’s idea is certainly interesting!!!

      Good Morning,
      I just looked over your site listing all the marinas along NC and the fuel offerings. Great job. I certainly appreciate all of the hard work and time that went into putting all of that together.
      I would like to let you know about CNG and how this too can be obtained though potentially not as easily as propane is as propane has become the defacto fuel these days ~ even though CNG is bar far a safer fuel to cook with (lighter than air).
      Any municipality that fuels their fleets ie: buses, trucks etc, and taxis or any other “green” vehicles that use CNG, well they have a CNG pump that is open to the public. Where I live in Maryland ~ Montgomery County ~ we have such a place. It is a County fueling site for gasoline and diesel but now there is also access to CNG. You simply scan your credit card and punch in the pump number and then fill up.
      There are two sides to the CNG pump. One is for 3600 psi and the other is for 3000 psi. I own a 34 foot sailboat that cooks with CNG. I have made an adaptor that allows me fill my CNG tank at this fuel fill. Where we used to have to do a “tank exchange” costing anywhere from $50 to $100 per tank, I now completely fill up my own tank for $1.25. The cost of making the adaptor ~ getting the various parts was about $225 and I have more than made back that initial outlay over the several years I have been filling the tank myself.
      I realize that geography will be the killer to our access to municipal CNG fuel sites along the ICW. But as we go forward I offer all of the above as one more option that in some locals may be convenient. Just as propane users carry spare tanks, so do CNG users.
      Very kind regards,
      Denise Gill

      By the way, the parts list for making your own CNG adapter can be obtained here:

      Good Morning,
      Thanks very much for you nice email and for this posting. While I would love to take the credit for putting this parts list together, I merely downloaded it from our Catalina 34 website and share it with anyone else who might be inclined. I figure if I could make it, it certainly can’t be too difficult. I believe, as we go forward with `clean energy’ CNG availability will increase.
      Again, thanks and I enjoy reading the Cruiser’s Net!
      Kind Regards,
      Denise
