For anyone who may be confused: “Captain” is the sneaky sneak formerly known as “Bucky”.  As far as I can tell, this move has the following effects:

1) The monkey/apple/curse special motley combo now refers to em (no big deal)
2) The Captain may be prevented from vetoing adventures (this is open to interpretation—see the last sentence of Rule 2.9)
3) If we lose an encounter with a Kraken, e is sent to Davy Jones’ Locker, not the Captain (OK, this one is pretty funny)
4) Similarly, e is punished if we lose an encounter to a Ship of the Line
5) E may declare victory after having been Captain for 3 full days (pretty serious—see first paragraph of Rule 2.18)
6) Something incredibly silly happens in case of successful mutiny (see last 2 paragraphs of Rule 2.19)

Cute scam.

Not particularly. If this requires more ruletext tightening to prevent this kind of naming scam, I think it will make the ruleset even more clumsy. I recommend social smackdown.
