Yes a good coal stove you make your own coal from your own trees but you have been outlawed and the Coast Gard will not let you have it.
So your options are CNG,Propain,Methain, and the OIL company loves you.
Or go Electric. Or put in a fan that will blow the gas out if there is a leek.
Have a good year.

Re: CNG Conversion

Here is a quick and dirty write-up about the CNG conversion I'm doing right now.

Re: CNG Conversion

There is a sealed locker already installed from the factory with a vent overboard. I have to use the 6lb LPG bottles to fit, but its worth it not having to mess with rebuilding the locker.

That works. I will need to make a sealed box or install on the rail. But like you I can get Congress right now so while I am just coastal cruising I have 3 extra cng bottles so it will be a future project for sure. I enjoyed checking out your projects. Thanks and happy sails.

Great idea ! What daily quantity of beans will produce this result ?

Are the dried varieties better or worse ?

Re: CNG Conversion - (Update)

Just talked to Todd at Sure Marine about converting my 1994 Seaward CNG stove/oven over to propane, and he told me the conversion kits are no longer available. They ran out of stock about a month ago, and since the company that manufactured the control valve went out of business, there are no more to be had.

So now my options seem to be buy a brand-new stove/oven for $900 to $1000 or find a good used one.

I've been planning to do this conversion for two years, and kept putting it off to go sailing and take care of other issues that I thought were more important, and now I've screwed myself.

I've already installed the propane locker and tank, and this was going to be the final step.

Do I have any good options?

Re: CNG Conversion

I am burning propane in a CNG stove right now.The person who sold it to me said he put a different size jet in two of the three burners.But I cant tell the difference.They all burn the same .The only thing I dont like is the flame adjustment when I want the flame really low.It needs a delicate touch and I am not sure how it will go when the boat is rocking and rolling.I say,if you can do it without great expense,connect the stove to propane and see what it does.

Re: CNG Conversion

From talking to Todd, the main problem is the oven. The burners all have jets that are easy to unscrew and replace. The oven has this zinc casting that controls the pilot light and the temperature. This is the part that is no longer available.

The oven control is supposed to have a screw that switches the gas flow from a CNG orifice to a propane orifice that is pre-drilled in the casting at the factory - thus making it easy to change the oven from CNG to propane. But, Seaward, to save a couple of bucks, supposedly had the controls made without the propane orifice. So the screw does nothing but cut off the gas flow entirely.

Maybe I can live without the oven and just use it for extra storage. How often do cruisers use their ovens?

Re: CNG Conversion

OK, now I'm hungry. I read the whole thread, and it looks like its about 50/50 on whether or not an oven is useful on the boat.

So, like in all other areas of life, my wife gets to decide.

Re: CNG Conversion

Try an appliance repair shop, or an RV parts supplier.
