I'm quite interested in what rules there might have been for the copyist -- did they have rules, like we do here, of "put down what is in the log, not what you think should be in the log" ?
I ask because if you look at the 0900 activity entry compared to the 1300 activity entry on http://oldweather.s3.amazonaws.com/ADM53-69210/ADM53-69210-027_0.jpg
, there are two distinctly different activities being recorded! (scrapping vs scraping)
It's very definitely the same writer, and in both places the word is written without apparent hesitation, scratching out, squeezing in an extra p, or anything else that suggests he was in any doubt how to spell the word. Did he copy it verbatim, knowing that whoever wrote the original had miswritten but he had to make an exact copy anyway, or did he unconsciously make a mistake himself?
In re the boat's book that mutabilitie saw lost overboard, maybe it was the owner's manual?
