This chapter is told from the perspective of Capital Sam. It is basically his general thoughts on how to commandeer a boat or other seafaring vessel. His whole thing is: don't over-plan it, just be ready to take advantage of a situation when one is presented, and don't be afraid to improvise. Kind of a good way to think about life in general if you think about it.
He mentions something about it being time to give Lullaby a try, which is probably foreshadowing. Unless it's referring to something that already happened that I forgot about. Maybe Leona can weigh in after lunch, she's here today.
