Cabin windows
No guns there. In fact, looking at the last set of plans on this page, I see room for only about 12 guns total -- 6 each on the main and quarter decks. I doubt the foremost ports would be armed (the bitts and cables are apt to get in the way), and there might be problems with the next set due to the galley flue.
Aft of the drop in the decks would be aught more than windows -- including the ports in the captain's cabin. Remember, that space would normally be subdivided by light wooden screens and cluttered with furniture
