Does anyone have a source for CNG for their hunter cooking stove. I understand it is supposed to be safer than Propane but I have made a dozen phone calls and no one refills the tanks. I'm in Worton Creek Marina. Anyone know of a source around there or what is the closest.?? JOE s/v Satisfaction

To convert a propane stove to
CNG usage would not be advisable. True that CNG poseses less risk of explosion but being stored at higher pressures makes it more risky to a fire. CNG is stored at 3000-3500 PSI while propane is stored at 140-150 PSI. Both fuels are highly flamable. It is the systems and the components used that provide the safety not really the fuels themselves. There are safe installation guidelines for both. Propane has been declared the standart for small tank portable usage fuels and CNG small tank filling stations are quickly dissapearing. If you are a cruiser you cannot find tank fills for CNG overseas. I can understand if someone already has a boat equiped for CNG that they would search for tanks and suppliers to keep from or postpone a costly conversion to propane but to intend a conversion to CNG does not make sense nowdays.

Just a minor correction. A CNG tank is a high pressure tank made of the same alloys as a SCUBA tank. The working pressure (max pressure) that you will find on one of these tanks is about 2250 psi. My CNG tank is seldom filled beyond 2100 psi. That is still a formidable pressure and taking all precautions are still necessary. So if anybody out there gets a fill above 2250, you are doing good, but the danger of the relief valve blowing out still resides and is the potential for a hot, hot fire. So keep the pressure below 2250 and you will be OK. Don't go complaining to the seller that they are gyping you. If the tank is overfilled, then the blowout valve will kick in. Also, although costly to do, CNG can be converted to propane with the proper equipment being replaced. It may still be cheaper in the long run to convert a CNG stove to propane. The big expense is finding a place to mount the propane tank into a dedicated locker outside of the main cabin. My CNG cylinder is currently stowed below in the salon.

Yup ...hard to find.
Our Legend 35 came with CNG and we used it this summer. We found a place to refill the tanks, but there are not many (none near us). We went through 2 fills this summer, and our thought was that if we had 2 tanks, then we could fill them both, and running out wouldn't be such a pain (it's a 2 hour drive to the nearest fill station for us). Question: Can a scuba tank be used (with the appropriate fitting)? The cost of changing to propane might be $500 with all the hoses, valves, etc. And they there's our stove, which would be very expensive to replace. It's old, and not sure about converting it to propane. The old one doesn't have any safety shutoffs. Chris

Try this link.
Joe: I have no idea where you are located, but here is a company that supplies CNG on the East Coast, Corp Brothers.

I'm from RI...
...and there are ample places located near me. I am just 15 mins away from the RI Corp Brothers, so I've never run into a problem. I bought a second tank, but a SCUBA tank has different fittings on it, so the conversion should be done by a pro. They wanted $200 just for the fittings when I got a spare. I wanted to use my old SCUBA tank too. This was the same price as the spare tank. I keep a spare aboard at all times, but we never go thru more than a tank a season anyway. All along the Northeast Coast there are a number of places (marinas, etc.) that carry CNG. Just swap the empty tank for a full one.

In your Creek
Joe You have marina on your creek, Worton's Creek Marina, that I have used to exchange an empty CNG tank for a full one. Here is a list of the other known locations where you can also exchange tanks. • Annapolis - Peninsula yacht Service (410) 647-8722 • Galesville - Harige Yacht Yard (410) 867-2188 • Georgetown - Georgetown Yacht Basin (410) 648-5112 • Greensboro - CNG Marine Supply, Inc. (410) 482-8288 • Havre de Grace - Tidewater Marina (410) 939-0950 • Grasonville - C&C Charters Maryland (410) 827-7888 • Oxford - Crockett Bros. Boat Yard (410) 226-5113 • Rock Hall - The Sailing Emporium (410) 778-1342 • Solomons - Zahniser’s Sailing Center (410) 326-2166 • St. Michaels - Higgins Yacht Yard (410) 745-9303 • Burt Jabin’s Back Creek Café & Supplies 410-267-6780 I know that the cost of exchange is high about $70.00 per tank and I have been looking into making the conversion but finding a location to store a 10# tank and container is not an easy on a 35.5. Looking foward to seeing you on our part of the the bay next year. Bob

70 Bucks? *yks
Gee, they have you by the *(&&^. I pay about $15 for my tanks of CNG for the exchange.

I think it was around $25 which included a new tank a couple of months ago when we refilled/replaced our's at Corp Bros. Don
