vape on the water?

I've never been a big smoker, mostly when I fish or drink. Lately I've brought a no-nicotine ecig with me because I found it's not the need for nicotine, since I'm not really a smoker anymore. It's just the need to break up the boredom when dropper loop fishing and stuff. I only ever smoked when deployed because there was not much else to do underway 5 months at a time.
