Ahh BB, but isn't that described as wearing.
Absolutely . Not sure if Alfred is a sailor or passenger so his terminology may be pedestrian . He talks about strong SW winds so I would guess he is talking about wearing when tacking off.
Yes, that would be "wearing" (Patrick O'Brien often uses it). Also, failing to complete a tack is "missing stays".
Alfred was the purser, and he starts his diary aged 29 years. If he had been apprenticed at 14 (I don't have the record, but it was customary), he would have been at sea for 15 years. His wife, Eliza, was the daughter of a Captain who was lost at sea. It seems likely that their language was thoroughly colloquial. Even so, they might have said and wrote phrases out of habit, rather than out of consideration, and the "off an on" part of it might have only been a casual way to round off the phrase without intending to mean anything specific.
Curiously, Alfred sometimes enters the latitude and longitude, but with more enthusiasm than accuracy, as I found when cross-checking his references with the newspaper accounts. It was not the purser's job to navigate, and his positions appear to be a long way off course. Perhaps he wanted to give the impression of speaking "nautical-ese" to a future audience who might not have known better. The "off and on" phrase could be the same kind of bluff.
Finally, on the subject of navigation, Alfred writes that the ship lost its way in the English Channel, near the coast of France, when approaching London, and had to ask a nearby fishing boat for directions. Alfred puts this down to "unknown reasons", which seems unlikely for a ship that has just circumnavigated the globe. I suspect that grog might have played a key part in this, but Alfred, being a Wesleyan and a temperance campaigner, probably did not want to disparage his fellow crew by accusing them of drunkenness.
If you have read this far, you have probably guessed that I have immensely enjoyed reading and researching this diary. It has been a lot of fun.
