You have apparentlly not read the WORLD HEALTH ORGANISATIONS own study on this subject- Their CONCLUSION, the results of the W.H.O study on ETS were"statistically insignificant" and there are more REAL scientific studies that reach the same conclusions. Please go to DR. M.SIEGELS blogspot "the rest of the story" as an advocate of tobacco control for 30 years even he cannot believe the junk science being used to back up smoking bans these days.
ETS is annoying,irratating and smelly to non-smokers,but it is not dangerous.
Back on topic, I have never been into ships, did a little research,wow I was surprised at how small those ships were. Defineatly a brave bunch of men who would cross the atlantic in one. I would have been a coast hugger for sure
