I don't think they need to be exactly the same throughout the sea forts but the white barrels (where they're either on outside requiring you to use pulley to rotate them in or bottom floor near vault hanging near the lower part with the water inside the gate) have by far the better food more top tier food like pineapples and meat both cooked and uncooked.
Correct me if I'm wrong but there are some sea forts that don't have any (I believe traitors fate in far ne) and some sea forts that have them both outside and inside. I feel like all sea forts should have only one set either inside or out, and all should have at least one for consistency.
