Now I know why pressurized alcohol stoves are out of use on boats — the Kenyon stove that was probably original equipment with my boat lit up alright — the entire unit became engulfed in flame when I tried to get it started. Luckily the previous owner left half a dozen charged fire extinguishers on board. only used one, but it was not pleasant. I plan to try and light the thing again in the morning, on a picnic table, not in the cabin, with the fire extinguisher nearby, but am probably going to buy a different model. There are a new generation of non-pressurized alcohol stoves that seem to be the norm, but as is also the norm with my new boat adventure, I plan to ask as many experienced folks as possible and gestalt my way to a solution.
