Has anyone switched from CNG to Propane? What has to be changed?

Yes, but it was expensive!

I had CNG which I liked very much but it is not available as much in my area and not at all heading north to Alaska, so I had to switch. I sold the H 35.5 which had CNG and bought the H 380 which has propane which why it is expensive. However, to be serious for a moment, I did convert a Vison 32 from CNG to propane and it wasn't that hard. West Marine had a box for 2 small propane tanks and we established a hose to run overboard from the box so any leaks was sent over the side. We put a sniffer on the boat and wired that in to the sylanoid in the box. Then I put in a top of the line stove that fit--I think it was for Force 10 but I don't remember. At that time, it cost me about $1500 dollars (the stove was $900) including some labor for the electrical work which I didn't want to do. It was easier to buy a new boat. :)

Bigger Boat?

Hi Les, I certainly sounds like it would be easier to get a bigger boat than do the retrofit. I'm not so sure I can even handle this one yet. Just bought it from my son who moved to San Francisco. Gene

Eureka! I Found GAS

Thanks Brian for the Corpbrothers.com web site. It was a big help! I can send my tank to them and they will fill and return it UPS same day turnaround. They also have a nationwide list of dealers on their site. Thanks again. Gene

...I live 5 miles from a Corp Bros. in Providence. Have done business with them for 6 years and very satisfied. I have also seen CNG a bit closer to you in Greenport, NY (Brewer's Greenport Marina) and also on the Connecticut River in Essex.

CNG to Propane

I switched to Propane by: Adding a solenoid at the bottle Adding a shutoff switch in the galley Replacing the fuel hose Adding 2 6 lb bottles (West) They fit in the same space Replacing the orifices in the stove This was a little bit of work but not tough. Greg on Temptation

explosive upgrades

The guys who sell propane and CNG systems espouse them. I saw a rather large fire two years ago in San Diego. The hot gases are truely hot on a sailboat. Jim
