Hi David
He may have been examined in intercept and azimuth methods, maybe not. That really is just speculation at this point.
What Robin wanted to know is if Worsley perhaps navigated differently when not on the Caird.
My response to that for a considerable number of years, is that he used the old methods, just as he did on the Caird. Why would he switch when his life was in danger. That would be an additional, frankly unacceptable risk. It would be error prone to suddenly perform using a method you haven't practiced. Worsley was exhausted, as were all the others on the Caird. At times the seas were huge. That's when he tried out some 'old timey' stuff? Not very likely and dangerous.
Frank Reed has also indicated that some othets used the methods Worskry did, out into the 1940's, so Worsley's use of the method in 1917 is completely unremarkable.
Frank has also presented the theory vs actual practice many times. It's not just words, Frank has been thru many a logbook. Sumilarly, lunars were on the examination for quite some time, long after nobody used them. Examinations are not a good method to determine how folks navigated in real life. For that, you go to the logbooks. Worsley's logbook is right in front of us! That's how he navigated.

My guess at his navigational exposure would be at his Fifth Officer posting in 1892. Therefore, examining training for 1917, as you have done, is 25 years too late.Please find a similar reference for the 1890's, 1900 at the very latest, when Worsley is certified as a master.My point was that in 1917 the Board of Trade did not examine for intercept/azimuth methods. It is therefore a reasonable assumption that Worsley, who had qualified years before, had not been examined in intercept/azimuth methods. He may have learned the methods informally.I have a copy of A Guide Book to the Local Marine Board Examination (1875 edition). New examinations had come into use in 1872. The celestial navigation requirements can be summarised thus:2nd Mate Meridian Altitude1st Mate Long by Chron & ex-meridianMaster....Extra-Master Lunars, double altitudes, equal altitudes, Sumner's method.Between 1875 and 1917 lunars were dropped and the Master's ticket upgraded. I note that Worsley was not an Extra Master. We need to know when the Master's ticket was upgraded to know if Worsley had been examined in Sumners. I do not have that information. I think that it is unlikely that he would not have been examined in interecept/azimuth mehods.
