How do you like this stove? I would like the single burner version one day but unpressurized alcohol seems weak to me. Am I wrong? They seem popular.
Different question, and there are a lot of considered replies in previous threads. While some boaters are adamant about their choice of stove fuel, I find it best to focus on the BTU output of a given burner. We can boil, fry, and (in our over) bake cookies. We had a propane cooktop on our prior boat for almost a decade and liked it just as much.
Aside from fuel choice, "system" requirements are much more complicated with propane in order to be both safe and legal. We have spent over a month at a time cruising, and our Origo 6000 does an excellent job.
So check the BTU output for the actual brand of burner on whatever make of cooker you fancy, and do not get wound up in fuel choices.
BTW, I have used Butane, Kerosine, Propane, and Alcohol to heat up our food over the last four decades.
All.... will have advantages and disadvantages.... and will burn the heck out of the frypan contents if one is.... inattentive... !
