I want to go back to Markus's post from the 23rd re : the course made good after turning the corner. I've done the figures myself and I think I broadly agree with him, the course made good was 265, not 266. Thanks to Sam, by the way, for helping me understand how these calculations are made.
Starting from a noon position of 43°02'N 44°31 (126 NM from The Corner @ 60.5°T), 5h50m of steaming at 22 knots at 240.5°T gets us to an actual turning point of
41°59′N, 47°03′W, an overshoot of 2.33 miles. From there, I assume a travel time of an additional 5h50m to get us to 11:40pm. On a course of 266°T at 22 knots, that gets us to
41°50′N 49°52′W. 22.5 knots gets us to 41°49N 49°56′W. Both longitudes are fairly close to the longitude of the wreck sight, but the latitude doesn't work out. A course of 265°T for 5h50m at 22 knots gets us to 41°47.6'N 49°51.7'W, while 22.5 knots gets us to 41°47.3'N 49°55.6'W, which is very close in both latitude and longitude. Of course, the math works out differently if you assume Titanic overshot the corner by a greater or lesser distance, or if you believe a clock setback had taken place before the collision (I remain unconvinced, personally).
