Just last saturday, 3rd Jan, I had a fire onboard, it was very small and nobody was hurt, but nevertheless could have caused a total loss in case it would not have been quickly acknowledged by the crew.
The fire started from a light fixture (20cm x 20cm) in the lower crew cabin below water level. The fixture somehow short circuited itself, started smoking and finally ignited the plastic parts in it. In less than a minute the whole cabin was smoke packed and triggered a fire alarm.
