I am confused as to where this Uboat went down. Looking at uboat.net, it seems it was "Sunk on 19 April 1945 in the North Atlantic south-east of Halifax, in position 42.19N, 61.45W."
However, [www.u-boot-archiv.de] states that it went down
east of Boston, and also gives the coordinates 42°19'N-61°45'W.

I just don't know enough about how the coordinates work to figure this one out. Perhaps someone could decode this for me.
Thanks very much!
