If we assume that in this published Cook's Lunar the MOST RELIABLE DATA as they can be estimated to-day are the following :

1 - the Observer's Position : "Ohamaneno Harbour in Ulietea", as depicted on the "historical" charts (which you now have at hand) and which is nowadays very easily recognizable on Google Earth, hence the following Coordinates : S 16°45'33" W151°29'48", and

4 - A date close to Sep 07th, 1773,...

How sure are you that Adventure was in Ohamaneno Harbour in Ulietea when the observations were made?

Looking at the ship's journal, it appears that Adventure was weighing anchor at 6:30 am in Owarre Harbor, Huaheina on Sept 7. At noon, it was 5 or 6 leagues from that harbor. At 3 pm, it rounded the 3 pm rounded south end of Ulietia

On Sept 8 at Noon, the ship anchored 4 or 5 miles off the entrance to Ohamanino Harbor, with 'Bola-Bola' bearing NWb1/2N

12:30 pm they began warping into Ohamanino Harbor. At 6 pm, anchored 1 mile offshore.

I expect that there is a calendar correction to be made, to equate with Greenwich time, but if it corresponds to one day, then the observations were likely made on the morning of Sept 8, ship reckoning, when it was more than 4 or 5 miles off the harbor entrance.
