Out of 38 cruise lines, there are only four lines listed below who make a statement on the use of e-cigarettes onboard their ships. As you can see below, some just classify the smoking behaviour of e-cigarettes as equal to smoking tobacco cigarettes, and are happy to send vapers into the midst of toxic tobacco exhaust. Perhaps some time in the near future, some cruise line will create Vaper friendly cruises?
