My understanding was that since voyages way back in the
days of exploration were sometimes years and they would lay
over places sometimes months at a time, that lunar distances
were done on shore to establish time for the ship's chronometers.
In addition to the math, it took sometimes up to four people to
to a lunar distance.
If I remember right, Columbus tried to establish his position by
use of a lunar eclipse on the island of Jamaica. His results were
pretty far off considering he was on shore.
