I do not believe all Stone’s compass bearings. in fact, he himself testified that the bearings he provided were only approximate. I do believe, however, that the Titanic could have moved some 40 degrees of her initial position in regards to the Californian. Stone said that the steamer he was watching started changing her bearing after she fired the first rocket. So it was more than an hour before she sank. Besides we do not know if he noticed the changes in the bearing right away. So let us make it one and a half hours. Assuming that the initial distance between the two one and a half hours before the sinking was 8 miles, the Titanic and Californian should have drifted some 5.5 miles in different directions for around 1.5 hours to make these 40 degrees of the separation, and it is possible. At some point during that drift (at around 1:35 Titanic’s time) they were at they closest approach, and then they were drifting away from each other.If you believe all of Stone's compass bearings, then you need to explain how a compass bearing could change from SSE to SWxW (that's 7 points - nearly 80°) can take place over approximately one hour of time for vessels about 8 to 10 miles apart, or whatever distances you like? Draw out the simple diagram and then figure out the strengths of currents needed to match the appearances. Then I might become a believer in what you are saying.
