+126 = 1675 - 56.2 =1618.8noon position of 43° 02’ N, 44° 31’ W. This position is a total distance run of 1549 miles from Daunt’s Rock over the course that was traveled.
1675.5 miles is not necessarily applicable to Titanic. It incorporates 126 miles, a figure arbitrarily derived by ‘fudging’ the evidence of 5th. Officer Lowe.For the work I did on the Titanic, I got 1675.5 miles from Daunt's Rock to the corner, totally consistent with that Olympic data.
From testimony given by the Titanic’s 5th Officer Harold Lowe (American Inquiry, p. 381), the course from noon to the corner was 240.6° true, and the distance was 126 nautical miles (after correcting what appears to be a transposition error of two digits in the transcript of his testimony).
At the noon 14th position,42° 54.3'N, 44° 50'W, Titanic was on a course of S 85° W [S 62° W true].which took her to the position of 41° 55' N, 47° 20.8' W at 5:45/5:50 PM .The course was altered to N 71°W (266° true) passing south of the Customary track to Nantucket LV.15173. (Mr. Harbinson.) I will observe your ruling. (To the witness.) Do you know at what time the course that the steamer was to take was mapped out that day?
- Yes, noon.
15174. And, so far as you know, was the steamer's course deflected at all from the course that had been marked out at noon; did it vary to the south, or in any way from the course which had been marked out at noon?
- Yes, I considered we went at least 10 miles further south than was necessary.
15175. Do I understand you rightly that in marking the course at noon, the course was marked 10 miles further south than you considered necessary?
- No. We had a certain distance to run to a corner, from noon to certain time, and we did not alter the course so early as I anticipated. Therefore we must have gone much further south.
15176. When did you alter the course?
- 5.50.
Navigation is not about "where we've been," but rather "where we are going."
The unsigned and undated "Ship’s Run Data", presented at the United States Senate Inquiry and purported to be a memorandum of Third Officer Herbert Pitman , SS Titanic, in my opinion contains too many discrepancies to have been authored by a highly certified and competent ship’s navigator of Third Officer Pitman’s calibre.Referencing ET article Keeping track of a Maiden voyage. ....what is the logic for adding 126 miles to the route distance of 1492.8 miles (from off Fasnet to Noon 14th Memorandum of Mr. Pitman) making a total route distance of 1618.8 nm ?
"I took over the headphone from him, and he was preparing to retire when Capt. Smith entered the cabin and told us to get assistance immediately. Mr. Phillips resumed the phones, after asking the captain if he should use the regulation distress call "C Q D." The captain said "Yes," and Mr. Phillips started in with "C Q D," having obtained the latitude and longitude of the Titanic."
In other words, Phillips waited for Boxhall to give him the position, as Boxhall described, but the first transmission may have been incorrect.
A more careful perusal of ET article “Keeping track of a maiden voyage” shows that the course and distance from off the Old Head of Kinsale to departure off Fastnet are inaccurate, and in fact puts Titanic on a course for a grounding on Fastnet Rock. The correct course is 252° distance 42 miles , making the departure off Fastnet 51° 20' N, 9° 36'W . Consequently, the noon positions calculated for April 12th , 13th and 14th are inaccurate.Do the math. It comes to 126 miles. He obviously came up with that speed by doing the opposite, dividing 126 by 6 which is a simplification of the actual time from noon to the turning point of 5 hrs 50 min.
Based on the purported Pitman Memorandum and real practical navigation your positions for Noon 12th, 13th and 14th are erroneous.Capt. Collins. Taking departure off Fastnet 3 miles south of what I used makes almost no difference in getting to the LAN locations I gave in my article.
