This is true, i have seen a decent amount of medium ships that do just fine. The whole point of this is that smaller ships suffer from this alot. Im not here to boast about what size of ship i like but rather point out that the game is easier to go bigger than smaller. Personally i prefer bigger ships but i know alot of people who want to stay small and nimble but struggle near the center.
You are correct, What i meant was volume which i will correct above!
