Jetboil stove modification for use on board.


Part of the fun of 'Drascombing', the unofficial term for messing about in a Drascombe yacht, is cooking on board.  Many people use Trangia stoves powered by meths.  I used a Trangia for many years while camping and latterly converted it to gas.  However, I have become an ardent fan of the Jetboil stove due to its compactness, light weight and efficiency.

Here's my Jetboil inside its protective recycled snow goggles bag... there is an orange theme here!

Everything unpacked...yes, it all fits inside the cup!  Clockwise from left:  
  • Sea to Summit 'X cup' made of silicone.  It collapses down so takes up almost no room and has a secondary role as lid for the jetboil as it fits, just, over the top.  
  • Aluminium Jetboil Sol cup (800ml:  500ml practical maximum for boiling).  
  • Windshield.  
  • Neoprene insulator.  
  • Mini carabiner hanging system.  
  • Flint and steel as a reserve in case the in-built electronic igniter fails.  
  • Burner unit.  
  • 100g (net) gas cylinder.
  • Tripod stand (fits onto all sizes of gas cylinder)
  • Pan support
The Jetboil Sol comes with a brittle plastic cup (broken), a poorly-fitting lid (discarded) and a thin neoprene sleeve with a useless handle and temperature colour change strip (discarded as there are other clues when water is boiling). 

First evidence of my modification is the little hole just below the rim.  Also evident is a previous mod - a windshield made out of the wafer-thin aluminium that beer cans are made of, here in its retracted and stowed position.

On board, unless dried out on mud, life is never still.  A boat will always find a movement even in calm waters which could easily upset a pot.  Many Drascombers have overcome this with bespoke stove boxes to keep spills isolated or gimbals to try to prevent spills in the first place.  I went with the gimbal idea with this project in an attempt to allow gravity to calm the waters and prevent boiling water meeting sailors before they were ready for it.

The modification couldn't have been simpler: 3 small holes drilled just below the lip of the cup to allow mini-carabiners to be attached.   


Here is the Jetboil hanging in my garden ready for testing.  The black sleeve over the windshield is a piece of wetsuit material, neoprene fabric, which acts as an insulator.  The stove's heat-transfer fins are so efficient that the neoprene does not singe or burn when in use.

Here's a short video of the system in use, with a helpful prod to simulate waves:

 It works fine in the garden; roll on the end of lockdown so I can test it for real!

Lockdown has eased and we picked up Valentine last week!  Today we spent the day hiding from snow showers and enjoying cups of coffee and tea using the Jetboil in situ.  It worked!  The Jetboil is suspended from the cabin doorway and hangs just above the centre plate mechanism.  In the background is our new loo, ready to be fitted once we can work out a way to squeeze it under the step.
