    I agree. I wouldn't expect any ordinary navigator in the  19th century to do
    anything like this. Rather, I would expect a typical  navigator with a
    chronometer to test it by ordinary time sights from the first  port with a trusted
    longitude, perhaps supplemented by occasional lunars while  in regions with
    uncertain longitudes. But, if this was putatively a voyage of  "exploration" (as
    it seems to have been, at least in theory), then I would  expect you might have
    an observer with greater astronomical skill.
