Is getting drunk 3x or 4x a week really that bad for a person?

I belong to a yacht club that is filled with people who (by my upbringing, which had not much drinking going on) seem to be every day- functioning alcoholics. They get drunk say 4 times a week. My common sense (and critical judgement) says these people are drinking too much. Yet, they seem to be having so much fun- and things dont seem to get to them like they get to me. Makes me wonder if I need to start to drink more. Seriously. I've always thought that alcohol in general, in excess- to me that means getting drunk0- is bad for you if you do it frequently. But now I am not so sure. Confused! Chime in with your opinions and experience. -
