Yes. They are somewhat tame vices by our standards. But nonetheless, the card-sharpers sound to have been fairly dangerous, to the wallet at least. Still, each to his/her own era. My own sketchy knowledge of this subject extends to booze (at any time), cocaine in the 20s forward (not personal experience you understand) .... and that's about it. Best ask Bob Godfrey - he seems to know a bit about historical vices, from diligent secondary research.
Lots of people count rivets, but I've not met a vice counter. (As opposed to a viscount.) There must have been quite a few vices aboard. I would imagine a woodworking one in the carpenter's shop and several of various sizes in the engineering spaces. Has anyone ever counted Titanic's vices?
Oh no. Any place that needs a vice counter is in serious trouble. Next thing you know, we'll have people standing around drunk still sippin' Jack D listenin' to AC/DC while a bunch of night doves do a strip tease on a busted up old table.
