It's been some years since I read the book but I seriously doubt that
an experienced ship's Captain would have set off without navigation
equipment. If I remember there is at least one reference in the book
of Slocum taking a lunar sight to establish longitude.

Likely he didn't have a chronometer though if he was shooting lunars.

My recollection is that he managed with a cheap alarm clock

Then he wasn't using it for navigation. Thus the Luna sights. Or he
was running down a line of latitude. Or he was using dead reckoning
for much of the trip which seems most likely.

Cheers,
