Kylo has never been on a ship, not one at sea by any means. He's taken to striding around as well as he's able on a deck that sways too and from and tries not to think about the crushing waves around them. How much water they're surrounded by and his own skill in swimming.

He's frustrated, having left behind his galaxy, his mission, his post and not of his own volition, while he hastily wipes down the canons as instructed. All the while muttering his fair share of curses, wiping the water out of his hair with a gloved hand.

"That's what happens on a boat. You get wet." He looks around for the source of the voice and finding none, sits down to give the sodden cat a scratch behind the ears.
