The 36-meter "Lady Jersey" had a fire onboard in the highly populated Monaco Marina. It seems like it was kept under control though.
If the relaxed attitude of the firefighters is anything to go by, maybe they understood immediately the problem and knew it could be easily controlled. But I agree, in the boots of Lady Jersey's neighbors I would have moved if I could, if nothing else to avoid smoke smell to stick around and inside my boat, possibly for quite some time!
