Hi from Bruce (cruised P&O Arcadia, RC Brilliance of the Seas, Viking Sea, Cunard QE).
My first post on Cruise Critic for some years, but can't resist adding my ha'pennyworth. Thanks to chengkp75 just above this post we now have a realistic technical reason proposed for sooty smut deposits on aft areas of some cruise ships like Saga's newest. Last month we were on Spirit of Discovery (the Biscay storm Nov 4th accident trip - got our full fare refund, as did all passengers we believe) and prior to Biscay we noticed no particular smuts around the Verandah terrace near the stern, but did see plenty of sooty smuts in the sofas area and deck game courts relaxation zone high up on deck 14(?) just aft of the funnel. She's nevertheless overall a lovely ship with a fantastic crew base of Philipino's.
Case proven. Cure still awaited.
