The pressurized alcohol stove is not a good thing.
You'll need to prime the unit by letting some fuel
pour into the priming ring. That in itself should clue you into it not being a very good thing for a boat.
Way back in the way back olden times when us fogies used to do crazy backward stuff like read books
and watch where we were going when walking they had pressurized camp stoves of a very similar design.
I'm here to say that when the options are an entire forest burning down with you inside of it or producing an inhuman amount of breath so you can blow out the inferno raging through the failed needle valve you can produce more wind
(hot air) than you would expect.
I guess those experiences prepared me to spew and chest beat on the Internet
so they must have been good.
Things got better when Colman came up with the Peak One. I don't remember having to prime that? In any case I used one of those for a few years until a very similar thing happened.
These days for hiking and camping I use butane canisters but there are some pressurized stoves still made for use at high altitude.
I've had catastrophic failures with every pressurized stove I've used. Even had a big flame up on a boat with a stove like yours when I was a kid.
I know, it's user error, I'm an idiot etc. Just ask anyone. But even so I would advise getting rid of the stove.
On my boat I have an Origo
because worrying about explosions isn't fun. But it doesn't work so well as an oven it takes a long time to heat up and then has pretty uneven heat. I've got an oven brick in there and will need to add a few more. But cooking
isn't such a big deal for us. It's a small boat and our trips are rarely more than a few days.
