The firemen told us that it is essential to aim the fire extinguisher at the base of the fire. The base of fire does not have any flame or color. It is a void, just above the pan of gasoline, where the oxygen feeds the fire.
That video was really eye opening (haha, sorry). But really, it was. You get *one* shot with the fire extinguisher because after that visibility is zero.Second, is the fact that down below, all boats are very small confined spaces. The moment you pull the extinguisher trigger on a powder extinguisher, it will go to zero visibilty. Instantly. There is a Youtube demonstration on this. You need to be far enough away and have your exit planned in zero viz. You'll be destroying visibility for every passenger attempting to exit too.
After I saw that clip I bought some fire blankets. For my boat, for my kitchen, and for my bag ‘o boat crap that I bring when chartering. It would be a lot safer and cleaner to put out a kitchen fire with one of these than with a powder extinguisher:
