    Something a little more prosaic: pot clamps.

    I'm probably going to stick with the Origo (give it a go, anyway). I'm sad I don't think I've got room to swing it - always had a swung stove in the past, always worked perfectly, cooked many a breakfast while beam-on to the annoying SW chop we get here, waiting for the longline gear to soak. "No worries" they all say, "scows don't heel much, have it fixed and just use pot clamps".

    Well, mine didn't come with pot clamps.

    I suppose I can make something.

    I looked on a facebook page this afternoon called "sailing on a shoestring" and almost immediately found two different types of Origo pot clamp which might just do the trick!

    I also think that the wind shield improves the efficiency of the burner. 
    With brennspiritus (94% ethanol) it burns better (the flame is lower and bluer)….now I know the difference between bio ethanol (100% ethanol) and brennspiritus (94% to 96% ethanol) :)

    Hi all,

    I was just curious to know how performs the Trangia so I made a boiling water test with her. 
    Boiling 500ml water with a starting temperature of 20 degrees in an open pot of the Trangia set, takes 6:10 minutes and 18,7 ml 100% ethanol.  
    Boiling the same quantity of water at same starting temperature with the Trangia kettle, takes 5:42 mins and 18 ml of 100% ethanol.
     
    I poured 20 ml fuel into the burner with a pipette. 
    Before starting, I let the burner warm up for 30sec. After boiling the water I let the burner cool down and measured with the same pipette the remaining liquid. I waited until the burner and the stove were completely cooled down before filling the burner up and starting the next try. 

    I was able to take the burner in the hand 1:30 min after extinguishing the flame. One minute later I could refill the burner.

    The flame was always yellow. 

    cheers Mauro 

    Hi Mauro, I've never seen a Trangia make a yellow flame like that. Ethanol is obviously much hotter than the brandspiritus I bought in a Dutch supermarket. It boiled enough water, about 300ml, to make a mug of tea in 5 minutes. Does pure ethanol coat your kettle with soot?

    You may be interested to know a 1½ litre Hawkins pressure cooker fits perfectly in a Trangia size 25.


    i have this amazing camping alcohol stove.  Like the Trangia, the support cone / wind shield directs the heat around the mug / pot, which makes it very efficient.  The neat trick is that the cone packs into the pot for travel. 

    the flame is almost invisible, if it is yellow and oversized, it is not running efficiently.  once the Trangia burner gets warm enough  it starts to burn better, perhaps the photo was taken too early.

    i do like alcohol for it’s relative safety and it runs with no noise, unlike a camping gas burner.  

    it would be interesting to try an alcohol burner with a Jetboil type top to see if this is any more efficient.

    Hi Asmat,

    thank you for the tips! 
    I’ve seen the pressure cooker on Amazon and I’m going to buy some brennspiritus too :)

    ciao Mauro

    Trangia stoves can be fitted with a butane gas burner, available as an accessory. Boils water  in less than half the time. The gas is supplied by a reinforced hose, from a disposable cartridge. I've only had one explosion, a small one, which has taught me not to change gas cartridges down below.

    I'd forgotten about this gas burner, I'd had the multi fuel burner in the back of my mind but they always seem to be out of stock. The multi fuel burner can run a Trangia on a gas canister or liquid fuels like alkylated petrol which some of us have on our boats now since Arne introduced us all to the merits of this fuel for outboards. Asmat, what was your experience of being able to turn the flame up and down with the gas burner, does it work well? Flame control is one of the dark arts of the Trangia alcohol burner. 
    The flame is easy to regulate quickly and accurately, provided the gas cartridge is kept upright drawing vapour only, not liquid. If liquid butane fills the hose, it takes a while to burn out. The only slight quirk is that, as vapour is drawn, the remaining liquid butane boils and cools down, so gas pressure begins to reduce.

    As for junks, they are some of the most efficient rigs around. They may not get you first to the windward mark but it terms of reward for effort and bang for the buck, are downright unbeatable. Yes, even when you have my expensive sails!


    Absolutely!

    I must say, I have a genuine Origo 1500 and I do not think the build quality is poor. It's very solidly built from 316 stainless. It is simple and well made although some of it's features might be called quirky.

    It is expensive for what it is but that is probably a by product of being made in small quantises and in Sweden, a country where people are paid a living wage unlike China.

    At the end of the day, it is a stove that you likely would only buy once and it will last you a lifetime.
