Frank Worsley went to sea in the late 1880's and swiftly rose into the officer ranks, getting his master's license by 1900. All of his training and practices were well established decades before the 'new fangled' navigation ever took hold.
Worsley was steeped in tradition, bound by training and reinforced by successful practice. There was little pressure to change, even when late in his career, the new navigation was taught. Worsley died in 1943, during the early adoption of St.Hilaire.
The methods he used should come at no surprise to anyone. He was of a different era.
Encouraged by the excellent analysis by members of Capt Worsley’s log, I used my limited resources to go back further to search for his layout, and found this by Coleman, published in 1846. Raper and Bowditch have almost identical methods. Table XXI shows how to get from (Hav) log to time.
All three authors also show how to calculate azimuth from the same data in a very similar fashion.
70 years later, Capt Worsley does not use methods devised by Sumner or St. Hilaire.
