No checks needed for the upper deck, as it's mostly trashed and empty, with little more than creaky old furniture without value to find. It does take a few minutes to assess everything though. As for the hold below, much of the cargo is still intact, though perishable items like food spoiled by now. There could be valuables however, which is why the more extensive search time. Also, no sign of any threat in there, it's silent with only the creacking of the wooden body of the sihp and the heavy rain falling on the decks above, so the search can be rolled in the first place.
