This is a strangely worded sentance. Are you asking on which ships smoking is allowed and are you also asking whether one can smoke in a cabin?
Also which period of time are you refering to, this year, next year or some mysterious time in the future?
Do you want ships where smoking is allowed or where smoking is prohibited?
