As I said I'll be polite first and as some have said they respect that and do what's needed to not bother anyone with their smoking. But I think it's obvious that there is a majority that don't want to be near a smoker And as I said smoke all you want as long as I don't have to smell it Also why do smokers think they have a right to smoke, especially when entire states are taking measures against it. My point is simply that MOST of us going out on dive boats, and I think that's pretty obvious, don't want to be around it at all. There are countless reasons not to smoke, ESPECIALLY, in regards to diving, and "second hand" smoke can have adverse affects on many of us. Here's something that I think is ironic, why does a smoker use deoderant?? i just recently came back from a liveaboard in Indo. the boat had a few spaces left and asked us if they could fill them. We told them no probelm, but absolutely no smoking, period, anywhere, at all. They completely understood. As far as getting violent heck no and wouldn't think of it but if you didn't accomadate my request I would take additonal steps, T/W captain, organize a keel hauling, bucket of water, entice you with cash incentives, offer you beer for cigarettes whatever it takes BUT as I said this only applies if I smell it. I'll go to the bow of the boat but I can't get any farther than that after that you're going to have to make the effort. Our experience with smokers is that few of them either care or realize how much their smoking effects the people around them. If they did would they do the things they do. Pull up to a traffic light and look at the ground, or the ground around the entry ways to malls, restaurants, airports, etc. How many smokers have butts in there cars ashtrays. They don't want to stink up their car so the toss the butt out the window, if smokers are so considerate then why do these conditions exist??
