(Sorry to hijack this thread)
I always used the Coleman stove when out on the ground in winter with the RAF Regt (well, when we were allowed hot food!), or a hexamine (solid fuel) cooker at a push (the hexxy is messy though, and the fumes are very bad for you- thanks MOD!).
I've been experimenting with different types of cooker on the boat since the gas cooker issue arose.
The Coleman is fine in cold weather, but they aren't really considered when talking about cookers on boats. I think the trouble with Coleman cookers (I've got one) on a small boat isn't the danger from the fuel and vapours themselves (this is the supposed reason against them but it can't be any more likely or dangerous than a gas leak), more it's to do with the 2 foot jet of flame that you get when you first fire it up!
When there's not a lot of headroom you can imagine the effect... I've tried mine on deck and it was OK, but if the canopy was up I think it might be risky and using it in the cabin is just daft!
Not sure if a Primus also does this?
I have tried a Trangia (meths camping cooker) which worked very well, apart from it is designed to be assembled on a stable surface (i.e, not on something floating on the sea) and so I think there's a risk of it 'coming apart' at the least convenient moment. Having said that we did use it to succesfully warm up tins of beans and sausages on Rob's boat, with it precariously resting on his chopping board which hangs out over the side of his boat!
So third time lucky... I have got hold of an Origo cooker, which in essence is a boat-friendly version of a Trangia. So, no danger from fuel spills or vapours, or of it coming apart or it being affected by cold weather.
Being a 'Marine Solution' they are priced at a premium, but I got one for about
