After the Aran (Arran?) dustup, where did the run take place?

How many runs were made to make the top speed official? (In land speed records there are multiplle passes over a course to establish the average, and to account for winds and other factors)

Results?

The gangplank accident took place so soon after, and assumed most of the publicity, so if such data were presented, I missed it.

Try these 2 URLs for some info -

Arran - a very pretty little Island.

Haven't found anything else so far........

There hasn't been a lot of information released to the public. There was a press release that came out on Thursday before the accident but it only said that she exceeded 30 kts several times.

Other feedback from knowledgeable sources indicates that the ride is incredibly smooth. Specifically, you don't feel any vibration at any speed. If you are away from the windows it's supposedly hard to tell the ship is actually moving.

I believe that the 32kt speed of QE2, even after the re-engineing (?) was predicated upon a requirement for 5-day crossings.

A cost benefit of cosseting passengers for another night vs the costs of additional tons of fuel required led to the establishment of a 6-day crossing, w/less fuel required.

I think.

25 - 28.5 knots cruising speed (maximum 32.5 knots)

She doesn't need to run more than average speed of 27 knots if she runs in 5 days.

27(knots) x 5(days) x 24(hours) = 3,240 Nautical Miles

She can covers 3,240 Nautical Miles in 5 days

Actual Nautical Miles from Distances between Ports Pub. 151 published by the Defense Mapping Agency. U.S.A.

New York to Bishop Rock 2,937 Nautical Miles

Bishop Rock to Southampton(via Needles Channel) 232 Nautical Miles

2,937 + 232 = 3,169 Nautical Miles

Here's Photo of the QUEEN ELIZABETH 2 off The Needles from

Here's an article from here

And so we set off. Down the Solent in the late afternoon sunshine amid a flotilla of pleasure boats, past the Needles with the wind quickening from the Channel, past the lights of the Lizard, and out into the encircling darkness of the Atlantic. Here, several old salts squaring up to the breeze on the prow referred darkly to the miseries of convoy duty and the U-boat menace, though it was not exactly clear to what extent they'd had personal experience of this.

like you, I am a bit disapointed by QM2 speed results.

The contract called for a maximum speed of at least 29.35 knots and QM2 exceeded that, albeit by a small margin, on a sustained basis on her second trials. The pertinent question is what speed does she need to maintain for 6-day crossings and how much she has in reserve to make up for delays. Assuming that she will use the same route as QE2 for her 6-day crossings the maintained speed turns out to be about 23 knots (based on QE2's experience, see below) under normal conditions, leaving plenty in reserve. However, how the pods will perform after being driven for 23 knots for a few days will only be known once QM2 enters service.

Her stated 28.5 knots sevice speed notwithstanding, on her eastbound 5-day crossings (actually 4 days 19 hours from pier to pier), QE2 averaged 27.5 knots from Ambrose to Bishops Rock under normal sea conditions, slowing down in the channel. Of course in the severely speed-restricted waters of New York to Ambrose and Southampton water she only travelled 10 knots. On her 6 day crossings, QE2 only needs to average about 23 knots over the same route from Ambrose to Bishop's Rock to meet her schedule.

As stated in an earlier post, on her eastbound crossing of July 9-14, 1985 QE2 averaged a speed of 31.5 knots from Ambrose to Bishop's Rock under perfect sea conditions. (We left New York 2 hours late, took a longer route, yet still docked in Southampton 4 hours early). I doubt that QM2 will be able to match that, but she doesn't have to.

SS: QE2's full-load displacement is 49,000 tons give or take 100-200 tons.

I guess that 49,000 tons is pre-refits or original?
It would be interesting to see how much displacement she gained against tonnage!

I would imagine that it is still about the same since her full-load draught has not changed. Nor has her hull shape. The extras added by the refits would affect her LIGHT load displacement while her full load displacement would still be limited her freeboard requirements. Any increase in her LLD would be offset by a decrease in her deadweight.

You mention 35 knots. I wonder why the figure 32.5 is quoted as her max today. It seems to stem from the max reached on her 1968 sea trials. Yet she reached 35.5 knots on her 1987 sea trials after re-engining. While having to remove the Grim vane wheels shortly after returning to service might have reduced her top speed a bit, I doubt that her top speed was reduced to 32.5. Perhaps it's simply a policy change intended to avoid over-heating of her motor coils.
