Not me. I have suppressed several solvent fires using various extinguishers, CO2, dry chemicsl, etc., and they all work, are controllable, and can be directed where you want them to go. On a boat, I want directional control to the max. Sure, for a house fire or dumpsters, I can see the value, especially for SCBA equipped and trained firefighters.
But tossing one of those into a cockpit, surrounded by open water? I don't think so.
In a boat, whether FRP, wood, or steel, I want good suppression, directed at the problem, with a known, safe exit at my back, ready to bail out if there is a hint of an out of control blaze.
