In Ultimate Combat, I see cargo capacity is listed among the stats for various ships. Are there rules somewhere for determining how much space different types of cargo take up? What about rules for provisions? As in, how much food and water would you bring on an ocean voyage for X number of days and Y number of crew, and how much cargo space would that occupy? I don't remember seeing that in UC or the APG, but I may have missed it. Is it in another book somewhere?
