Most of the smells that they complained about were diesel fuel, sump water and farts.
Wait until they start slowing down those air recirculation pumps because(there's no need to scrub cigarette smoke) to save money and 'go green' - give it a year and the 'sub sickness' reports will most likely come out....
Actually sub sickness is well known.
The Boomers I have known have told me that with in a few days of setting to sea the majority of the crew would come down with a cold and get over it in a week or so.
Then after a six months deployment they would pull back in to port and after a few days in port the majority of crew would be sick again.
