This was a early rise shapshot, and only the early birds were up for this one! and I guess some were preparing for disembarking later on! mrdot.

Fabulous photo. However, I am intrigued by how few of her passengers have appeared on deck to enjoy her arrival

one thing,,you write "engine exhaust" directly,, Can I assume safely you mean "engine room ventilation air " ?
because if exhaust air is directly ventilated as you write one could understand or read it that, then nobody can work in the engine room anymore. If you ever been in a engine room with a "only" leaking exhaust pipe you surely know what I mean .

Unlike hydrodynamics (which are crucial), aerodynamics have little influence on a ship speeds. Ships do not normally move fast enough. It is reckoned that road vehicles are not significantly affected by wind resistance at speeds lower than 40 mph/60 kmh/38.76 knots.
Wind tunnel testing is mostly done to ensure that funnel designs efficiently keep flue gases clear of passenger decks under varying wind and speed conditions.

I was AB on Oriana in 1967, seam to recall storing the mechanical deck scrubbers in the dummy funnel, could be wrong?

Great photo Mr Dot

Denis, I've no knowledge regarding the building practices of modern cruise ships. At the time of Oriana's construction speed (and the reduction of passage time)was an essential factor, so in those days wind tunnel testing was undertaken. I do know that wind tunnel tests were carried out on various proposed funnel designs for the original Royal Viking Line trio.

Clive, extensive wind-tunnel testing you said? I wonder if such is carried out for modern cruisers that have aerodynamics no different from the ones of a rectangle building!

Thank you Clive. All very logical and clear.

Orian's aft funnel was there for a real purpose other than just decoration. Her larger, forward, funnel was directly above her boiler room and as a result of extensive wind-tunnel testing in the early planning stages of the ship's design her bridge was modified to include a wind trap at either side of the funnel base. The second funnel-like structure a little further aft is the engine room ventilation stack. Traditionally, engine room exhaust air was allowed to rise up the engine casing and escape through skylights or other outlets at the top of the superstructure. However, on Oriana, the absence of such and escape route, and the excessive heat from her compact and powerful machinery made this stack necessary. The volume and temperature of this exhaust air were both sufficiently high that there was concern that if it were not discharged high above the decks it would be blown downward back into the engine room and accommodation. Oriana's naval architect was apparently not tempted to turn the engine exhaust into a second dummy funnel, balancing the real one. To have done so would have spoiled the ingenious pyramid profile of the ship. Also, weight economy was far too important to allow for any such structural excess.

A beautiful sight indeed! Can someone tell this ignoramus if the aft funnel was only for decoration, or did it have a job?

And it's white smoke, but not holy smokes, so no announcement from these shores, but an early arrival!

Stunning!!...and some smoke!

Beautiful photo Mr.DOT

Thank you for sharing

brgds, tvtech

What a marvelous shot! Well done!

Maybe not the greatest lines of the classic ships, but they look good against the 'epec breakaway' graphic walls of the present lineup! mrdot.

Beautiful shot (beautiful ship) utterly superb.

Fabulous photo, Mr. Dot! She's my favorite P&O vessel. Thanks for sharing.

Gorgeous photo! Not the prettiest ship, but certainly great.
