Don, we have CNG on our boat and I really ...

like it compared to propane. I carry two tanks, one as a spare. I do a tank exchange with our local marine chandlery for about $28. A tank lasts me a season. Our propane BBQ on deck comes in handy for other cooking needs. It is my understanding that you have to change the jets on your existing stove. As far as locker storage, it needs to be sealed and vented properly, and some way to secure the tank. Propane also produces a considerable amount of moisture as it burns, unlike CNG. Hunter Marine Customer Service can advise you where they put the tanks on your boat model and also safety issues to consider in doing so. Terry

Terry, that's right about jets

We converted several appliances to propane from NG when we built our new home. Any technician carries the jets to go either way. But they must be the correct type. The gasses are not interchangeable. I don't know witch one goes boom though, if hooked up wrong. :)

just bought the parts

I just bought the parts from a local Seward distributor for the 3 burner/oven on my 89 Legend 37. Cost about $130. Can give you details if you want them (and if you have a Seward unit).

CNG, WHY CHANGE?

Don; Granted it is more difficult to find CNG around, but I feel it is worth the trouble for the safety reason alone over using propane. Propane gas is heavier than air I am told. If that is true, any gas leak would tend to accumulate in the bilge, unlike CNG which is supposedly lighter than air. I don't have to draw you a picture of what can happen. I left the CNG set up on my 35.5 alone. Good sailing. Fred Miller, M/Squared
