The dates and locations are quite specific. The error in latitude will be twice the Sun’s declination. For the Orkney’s the latitude difference is 23° and the Sun’s declination on the 19 April, 1815 was around 11°N. For Christian Sound (Kritiansund) the latitude difference is 27° and the Sun’s declination 13.5°N. It would be no easy task to construct a fanciful tale in which the differences in latitude, changes in declination and traverse times all line up so well,
