Both of mine were more than 12 so I bought 3 new ones...one for each sleeping cabin and own within arms reach of the galley and engine room.
FYI, if you have an extinguisher without a date stamp...it is way more than 12 years old. One of mine was and it is no longer in service.
Actually, I just checked one in the engine room today (5 years old, a pretty white one) and it was dead center in the green, but light as a feather. I doubt seriously it would have been much use in a fire, but all you who say "check that it's in the green and you're good to go", here's hoping you don't have that happen when you need one, for real!
