Haha! I asked the same thing. Fortunately, it is a hot requested feature from many players in pirate101, so, I think one day, we will get our little cabin aboard our ships!
I just hope there is a good window where you can see the outside too, and have our crew standing in our room or something, or be able to decorate that room with some furniture or even a roaming skarakeet pet!
why not have a meeting room like in the tavern? where you can promote your crew or start their personal quests. now i dont want to take away the taverns basement either, but instead of having to fly all that way or porting to skull island....why not have a meeting room on saythe bigger Galleon ships??
