    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?
