I was on the old Union Castle/SA Windsor Castle, Southampton to Cape Town way back in '77. Cabin was well to the forward, outer starboard on/under the surface.
Felt pitch and roll well, despite the stabilisers. Minimal time spent in the 4 berth cabin, only 3 of us to start and the God Botherer some how disappeared after night one.
Great 13 day trip.
First airplane was a Viscount between Bulawayo and Wankie, aft of the wings. A bounce was felt in flight and those wings did flap about, the seats behind the cabin bulkhead were pointing backwards, a lá Military.
After similar flights as a younger person, I do not care. Peace & quiet is want I require, not self important, noisy or agressive SLF.
