I have to disagree with that statement. Smith set the time to turn the corner at 17:50 ATS on the 14th. He expected to reach LAN on the 15th 18h 57m later. If following 264.75°T, the charted course from the corner according to Boxhall, the ship would reach 41° 22'N, 56° 16'W at LAN on April 15th. This if only the ship was making 22 knots from the corner. LAN for that longitude occurred at 15:45 GMT, 47 minutes later than it did at LAN the previous day which was 14:58 GMT. The total miles run, if things would have followed this way, is 126 miles before the corner plus 417 miles after the corner, for a total of 543 miles from LAN to LAN. That's just 3 miles less than the previous day's run. Yes, by setting the time at 5:50pm to turn the corner, Smith allowed for a slight slow down from noon to the time they turned when he set that time.

You say: "Smith set the time to turn the corner at 17:50 ATS on the 14th".

He certainly did, Sam, but do you know when he did that? I can tell you now, without fear of contradiction it was not until well after Noon sights.

Then you say "He expected to reach LAN on the 15th 18h 57m later." I have to say it, Sam; that's nonsense.

Having done it more times than I care to remember, let me tell you exactly what happened on

*Titanic's* bridge shortly after Noon sights on April 14, 1912.

In all probability, Captain Smith would have got out his sextant and joined the seniors just before Noon. The navigators would then have calculated the results and produced the latest voyage data which would include:

Noon position.

Present course.

Distance traveled from the previous Noon.

Average speed from the previous Noon.

Course made good from previous fix position.

Distance travelled from previous fix position.

Average speed since previous fix. Total distance travelled.

Course and Distance to the next alteration position. (The Corner)

In other words, they would present the captain with a situation report.

When he received this, Captain Smith would retire to his chart room and review the report.

it is obvious that he did not plan a speed run before Noon April 15. Now this is where you and I differ.

By calculation, and you can, if you wish, check it yourself, the Great Circle distance from 1 mile south of the Fastnet Rock to the position of The Corner in 42 North, 47 West is exactly 1, 618 nautical miles. Since

* Titanic* had clocked-up 1,494 miles since she started on her Great Circle course; at Noon on April, 14, she had 124 miles still to run before she turned.

At Noon, April 14, Captain Smith was told that his ship had averaged 546 nautical miles for the previous day's run and therefore had averaged 22.1 knots of speed. Now the first thing the captain would do would be to determine where he thought his ship would be at Noon on April, 15. From this, he would then issue an order for a clock change to be completed at Midnight April 14.

If the captain had thought that his ship would repeat that speed performance for the next day's run until Noon, April 15, and cover a distance of 546 miles, he would simply have deducted 124 miles from 546 and to get 422 miles to run on his next planned course of 264.75 True from 42 North, 47 West. Not only that, but he would calculate his ETA turning point and get a turning time of about 5-35 pm , not 5-50 pm. Using the Traverse Table, he would enter with 422 miles on a course of 265 True in latitude 42 North and get a longitude change of 566 minutes or 9 degrees 26 minutes, giving him a DR Longitude for Noon April 15 of 56-26'West. The LMT for that longitude is 3 hours 46 minutes SLOW of GMT therefore at Noon ship time, the equivalent GMT would be 15d 15 hours 46 minutes. Since the Noon GMT April 14 was 14 d 14 hours, 58 minutes, he would have had to alter his clocks by 48 minutes so that solar Noon on April 15 coincided with ship time 12 o'clock.

However Captain Smith would not do as you see above because he would know from experience that his ship would encounter what was then thought to be The Gulf Stream, so he would expect it to set against his ship for at least 6 hours at about 1+ knots. He would therefore estimate that his ship would be 422 minus 7 = 415 miles west of The Corner at Noon April 15 and that he would increase his westerly longitude by 558 minutes - 9 degrees 18 minutes, giving him a DR Noon 15 Longitude of 56-18'West. The LMT for that longitude is 15d. 15 hours 45 minutes. therefore he would issue an order to alter clocks 47 minutes at midnight.

At 2 pm and 4 pm on the afternoon of April 14, he would have visited his bridge and noted the patent log reading and the sea temperature readings. These would tell him that his guesstimate was pretty accurate and that his ship was now being held back by the expected current. He would make an educated guess at it's direction and calculate where he thought his ship was at 4 pm. Then, and only then, would he fill-in his order book with the instruction to alter course at 5-50 pm
