I now continue from my post of September 26, 2008, 241 a.m.
Now Lord says he see the light of a ship while talking to the engineer and at some point goes to the wireless operator, Evans. Evans tells Captain Lord the only ship he is picking up is the Titanic. Lord says the ship I see is not the Titanic. It does not have the blaze of light of a major passenger ship. He tells Evans to send a message to Titanic warning her about the ice.
This message is time stamped at 9:05 p.m. New York time by Evans. To be as conservative as possible I will only take one minute for Lord to walk to and talk to Evans. And again to be conservative I will assume Evans time stamped when he began to send the message, not after sending it. So Lord is describing this ship at 9:04 p.m. New York time at the very latest. Now Californian, based upon her noon longitude of 47 25 W, is running her clock 1 hour 50 minutes ahead of New York time. So Lord is describing the ship at 10:54 p.m. ship's time at the latest.
Lord says the ship stops about 11:30 p.m. So there is a minimum of 36 minutes of steaming between talking to the wireless operator and seeing the ship stop.
Now lets see if this could be the Titanic. Titanic is on a course of S 86 W true or 266 true. She is steaming at 22 knots. She covers 13.2 miles in 36 minutes.
We are told her bearing at 12:10 p.m. from Californian when stopped is SSE by the standard compass. A point is 11.25 degrees. Stone is giving this bearing in units of a point (11.25 deg.). So we can't be more precise than half a point with this bearing or roughly 5.5 degrees one way or the other from SSE. The compass error for the Californian on her ENE heading (by compass) is 22 degrees west according to Captain Lord. So the true bearing is 135 degrees (SE true if precise to one degree) plus or minus 5.5 degrees.
I will do my calculations for a true bearing of 135 degrees and 140 degrees to keep it simple. The bearing of 140 degrees would place the Titanic closest at 10:54 p.m. when Lord talks to the wireless operator, as I will demonstrate. I will skip calculating 130 degrees, as that would place Titanic farthest away.
Some suggest the Titanic stopped 12 miles off from the Californian. I will also use the figure of 13 miles off.
We can draw a triangle and use trigonometry to calculate how far away the Titanic would be at 10:54 p.m. Californian time. At these distances the difference between spherical trigonometry and plane trigonometry is just a matter of feet. It is a negligible difference.
The leg of the triangle from Californian to stopped Titanic is 12 miles. The leg from stopped Titanic to Titanic at 10:54 p.m. is 13.2 miles. If the Titanic bears 135 true the angle between these two legs is 131 degrees. Now we solve for the leg between Californian and where Titanic was at 10:54 p.m. and we find it is 22.94 miles or 23 miles using our level of precision. But Captain Lord can only see a light 145 feet above sea level even using the maximum formula for refraction 21 miles. The masthead light will be over the horizon from Captain Lord standing on a deck at most 30 feet above the waterline. He couldn’t see it at 10:54 p.m.
Lets push the Titanic out to 13 miles from the Californian. Now its distance from Californian at 10:54 p.m. is 23.84 miles or 24 miles, which is even farther away. Captain Lord can’t see it.
Lets change the true bearing for the stopped Titanic from 135 degrees to 140 degrees. We cannot guarantee Stone was more precise than half a point (roughly 5.5 degrees) with his compass bearing. If Titanic stops 12 miles off she is 22.46 miles off or 22 miles at 10:54 p.m. That is still too far for Captain Lord to see. If Titanic stops 13 miles off she is 23.34 miles off or 23 miles at 10:54 p.m. That is still too far for Captain Lord to see.
It is very difficult to conclude the ship Captain Lord sees at 10:54 p.m. at the latest is the Titanic.
But perhaps one may argue Titanic stopped at only 11.5 miles off. Perhaps she stopped at 11:28 p.m. because Captain Lord only said she stopped about 11:30. Groves has her stopping at 11:40 p.m., which would put Titanic even farther away at 10:54 p.m. So perhaps everything worked out so that the masthead light was just creeping over the horizon and Captain Lord sights her at 10:54 p.m.
If all we had was the information above, one could conclude it is quite unlikely that Captain Lord sighted the Titanic at 10:54 p.m., but it is not impossible.
But there is more pertinent information to be found in Captain Lord's testimony.
To be continued.
