Astrolabe Model was a horse barge converted to an exploration ship of the French Navy. Originally named Coquille. She is famous for her travels with Jules Dumont d’Urville.
The name derives from a Voyage under the command of Louis Isidore Duperrey.
During the voyage the ship spent two weeks in the Bay of Islands in the north of New Zealand in 1824.
On the return voyage to France the ship sailed through the Ellice Islands (now known as Tuvalu). Early navigational instrument, the astrolabe, a precursor to the sextant.
Therefore, Coquille was renamed Astrolabe in honour of one of the ships of La Pérouse. She sailed from Toulon on 22 April 1826, towards the Pacific Ocean.
