I have over a thousand cassettes, a couple dozen CDs, and a fair number of vinyl LPs. I did have a number of 45s and a few 78s at one time. I do not have an iPod.
Maybe the waypoints listed on the ship's log were in the wrong datum. Perhaps the coordinates listed are in NAD-27 and the ship's GPS uses WGS-84. There might be an error in the north reference, with the captain reporting magnetic and AIS reporting true bearings, a 17-degree difference. There was a report of the captain being unfamiliar with the ship's navigation equipmant, which should be standardized.
