The second oddity is a knee-knocker* on that same deck. Mind you, this is way above the waterline. But this knee-knocker is very nearly knee-height on me, instead of ankle-high. I almost feel like I'm hurling myself through it!
Both things no doubt have structural reasons for existing, but they sure make getting around a pain in the knees.
* Knee-knocker. Term for the oval opening in a long passageway [hallway] that doesn't have a door on it. It just allows passage through bulkheads [walls].
