Thank you Paul. I did indeed post, "Angle on the bow appears to be from
the observer's bow to the target, while target angle is from the
target's bow to the observer." I either misread or ran into one of
"those" sites, which like me, professed knowledge it did not possess.

After spending a goodly amount of time with the Wikipedia article and
illustrative photographs trying to reconcile the seemingly contradictory
results, it suddenly dawned on me that the "Angle on the bow is a
variation of target angle used by United States Navy submarines"
statement also referred to the *target* vessel, not the sub. After that
things fell into place.

I have not seen the movie or read the book. I did however listen to a
radio play on a set the size of a dresser in rural Indiana circa 1957. I
recall the ending was distressing to a young boy.

There also seems to be a submarine computer simulation by the same name.
