Dusk and Synys have very different reactions to the ships constant motion after getting underway.  The kitsune, used to a lot of various methods of travel, takes a time to remaster her sea-legs and stays on deck most of the time.  Much nicer in the warm sun and cool ocean breeze than suck in a stuffy, creaking room below.  She enjoys herself resting, but doesn't do much else unless interacted with.  Dusk, on the other hand, absolutely hates this whole situation.  The motion waving her about ceaselessly bothers her immensely and makes her feel fairly nauseated.  Instead of staying around her counterpart like she usually does, the panther instead finds somewhere as close to comfortable as she can manage below deck to lay down.
