It doesn't "Seem" to fit Rostron's evidence, Sam ii corresponds to it.Your explanation, Jim, in post 314 above seems to deliberately have Californian taking a longer route to reach Carpathia by first heading down SSE then turning ENE so it can fit the evidence of Rorstron's sighting of C to the WSW.. If she spotted Carpathia as you show, and if the ice looked as you show, then why wouldn't Lord head straight for her until reaching the edge of the ice, turn perpendicular to the ice and then cross using the shortest distance, then head straight for Carpathia upon clearing the eastern side as I show (in black) below using your diagram? You also show MT stopped 5 miles away from your ice barrier. Why is that? And by the way, in Lord's Hydrographic office report he wrote: "encountered heavy packed field ice, extending north and south as far as the eye could see and about 5 miles wide; also numerous bergs could be seen."

A; Why would Rostron specifically use a corrected, i.e. True bearing.
B: You seem to be the one who is" fitting", since your above amendment is obviously designed to fit Captain Moore's estimate of the width of the barrier (not the field).
What you fail to consider, or perhaps understand is the process of finding a way through pack ice. You don't just batter your way through it, you send a man aloft with a pair of glasses to look for what is known as a "lead" throught the ice. A lead is an area of the pack which has fissures and perhaps the odd little pool of open water.
Californian did not have an ice breaker bow, Sam. Full speed through a solid barrier would have resulted in a real problem.
