To the List,
All - when doing a time sight at sea in period say circa 1780,
I seem to have gleaned "the latitude used was the estimated latitude"?
I assume this means latitude from a noon sight was applied (with DR
corrections)to the time sight that was done 2-3 hours before or after
the noon sight? while they certainly would not have traveled far at
say 6 to 12 knots some error would have undoubtably crept in due to
unknown currents etc. and it would not be impossible for the actual
lattitude to be off by 2-4 miles. How did they compensate for this
any ideas?
-Greg
