OK, tell me if I am off the wall...
EDITED:The heading was 319 degrees M with a variation of 15 degrees W which would be 334 True. (The variation is taken from the True not the compass.) The boat traveled for 48 minutes at 9.9 knots. That would be about 7.9 nautical miles.( using the formula 60 D St. 60xDistance= speed x time (in minutes)through algebra, distance= speed x time (in minutes) divided by 60.)Plotting the actual coordinates on paper, and the DR course, the current would be 3 knots at 236 degrees True.r.w.landau
