Lets see now , , , if you put enough water inside the boat it will continue to float. Right. On the other hand, what is the first thing you do not do for a grease/oil fire? I know, I know, you put water on it! Sheesh.
Not putting water on grease fires only applies to kitchens. In the case of shipboard fires, when Aqueous Film Forming Foam(AFFF) is not available, a spray of water is used rather than a solid stream. This deprives the fire of heat causing it to go out.
The reason you do not put water on a kitchen grease fire is that the additional latent heat in the oil will flash the water to steam spreading the flaming grease.
