When the boat was purchased it had the original princess pressurized alcohol stove on it. I’m sure that all have owned a boat have either read or experienced the horror stories that are associated with those types of cooking. Not to mention that the fuel used to it is one of the more expensive types of fuel to cook with.
I bought a butane single burner cook top the Iwatani ZA-3HP . It might be a bit over powered for most operations that are needed for cooking on a boat. 12000btu seemed like a good idea at the get go, but looking at the other btu of stoves, and cooktops, seems like 9k btu is about all that is needed. This thing will boil water and burn pancakes with ease. It is not so good at roasting marshmallows.
I removed the old princess, and that space works well to hold the case for the burner, it is also gimbals. I drilled out for holes, that the feet line up, so the cook top stays put on the surface. All in all it works pretty well. I got to test it this weekend with a trip up to Mission bay.
