IIRC In the UK gas installations on boats don’t need a certified gas engineer to install/check/certify them, unless the boat is used on inland waterways or is to be used commercially.If OP were to follow and comply with any of the usual regulated environments for boating. Gas becomes a difficult cooking method requiring a proper bottle storage outside and a whole lopt of other requirements including certification by a qualified gas engineer. Certainly the portable gas cooker types are outlawed. The problem, being that gas if it leaks settles into bilges and low areas and can not easily escape so any ignition source means disaster.
That means that methylated spirits (alcohol) or diesel /kerosene is remaining option. (or solid fuel) Kerosene or diesel takes a lot of heat to get it to vaporise and pressurized kerosene can be dangerous in the start up phase.
So really the best option is methylated spirits. Though is does tend to have less heat than gas or kerosene. It can be vaporised fairly easily and a spill can be extinguished with water. Now boat type cookers can be expensive and hard to find. Hiking type spirit stoves can be perhaps an option to be modified for a boat fitment. Don't be too fussed about gimbals unless with experience you find a need.
I have a neat single burner spirit cooker for my 21fter though it has not been fitted for many years. Bought 40+ years ago. Don't see the type here in Oz any more. Has a tank at the back. You run spirit into a cup then turn off the flow. Light the spirit in the cup let it burn till almost gone when pipes are hot enough to vaporise spirit running in to give a nice flame that looks like gas. Origo are very different I believe. So it is a matter of what you can find. ol'will

£36 for 12 litres delivered sounds like a fair price and low hassle compared to Camping Gaz.The days of using smelly meths on spirit stoves is long gone. Bioethanol is completely odourless, easy to store and a fire or spills can be dealt with using water. I use Bioethanol Fuel for Fires, Spirit Marine Stove Fuel, Alcohol Camping Fuel and BBQ Lighting Fluid | EkoFuel on our Origo 3k. There’s no dedicated gas locker on our Horizon 23 and I not a fan of cartridges. The Origo has been great.
Lack of an oven is rarely a problem, but you can buy a great proprietary gadget to go on the hob to do baking or heat up stuff that would normally go in an oven - I've forgotten the name of it, but it's in in the form of a ring: a circular trough with a lid, and Swedish IIRC.
These are better...What about the old Pyramid Toaster that sat on a hob ?? Haven't seen one in years ..
Interesting. Same boat as me. But I swear your Dometic stove looks identical to my Spinflow stove, apart from the name on it.The days of using smelly meths on spirit stoves is long gone.

Practically, it will be the same. I think there are various good clones knocking about these days and I’m sure yours will be just as good as one that says Origo on it. So simple, just a big Trangia. Wouldn’t be without on a boat this size.Interesting. Same boat as me. But I swear your Dometic stove looks identical to my Spinflow stove, apart from the name on it.
Meths isn’t hard to find - sold in many hardware shops (including B&Q last time I needed some) as well as many pharmacies (if they don’t have meths they will have surgical spirit which is a more refined (expensive) product). Even bigger supermarkets sometimes have it.Meths cookers are an option, but fuel can be dear and hard to find?
At the risk of thread drift. When you open ours, there are the two large round burners that you lift out to refill them.Practically, it will be the same.

You will have to remove those for the BSS exam.
Surgical Spirit will either have ethanol or isopropanol as the base with methyl salicylate and some denaturing additive to make undrinkable.Meths isn’t hard to find - sold in many hardware shops (including B&Q last time I needed some) as well as many pharmacies (if they don’t have meths they will have surgical spirit which is a more refined (expensive) product). Even bigger supermarkets sometimes have it.
When I was a student we used to use isopropanol from the lab - it wasn’t quite as good but was “free”. It is also sold in pharmacies, car parts stores etc.
I’m not sure how expensive meths is these days, but it is almost certainly not a significant part of the expenditure of owning and using even a 20ft boat.
Does a BSS examiner expect a cup of tea?You will have to remove those for the BSS exam.
They are to cover the burner when you have finished cooking to reduce loss of fuel due to evaporation.At the risk of thread drift. When you open ours, there are the two large round burners that you lift out to refill them.
Sitting in the bottom, doing nothing at the moment, are a number of round foam discs abour perhaps 3 inch or more diameter. I am sure they are supposed to do something but they are not at the moment. Any idea where they are supposed to be or what they do?
