Astrolabe/L'Astrolabe

Astrolabe was a horse barge converted to an exploration ship of the French Navy and was originally named Coquille. She is famous for her travels with Jules Dumont d'Urville. The name derives from an early navigational instrument, the astrolabe, a precursor to the sextant.
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, for a circumnavigation of the world that was destined to last nearly three years.
Astrolabe explored parts of New Zealand. In January 1827, the French explorer Dumont d'Urville arrived in Tasman Bay in the north of the South Island. A number of landmarks around Tasman Bay were named by d'Urville and his crew including d'Urville Island, French Pass and Torrent Bay.[3] Dumont then sailed along the east coast of the North Island. On 12 March 1827 Astrolabe entered the Bay of Islands.[4]
Astrolabe then visited Fiji, after which Jules Dumont d'Urville executed the first relief maps of the Loyalty Islands (part of French New Caledonia) and explored the coasts of New Guinea. He confirmed the site of La Pérouse’s shipwreck in Vanikoro (one of the Santa Cruz Islands, part of the archipelago of the Solomon Islands) and collected numerous remains of his boats. The voyage continued with the mapping of part of the Caroline Islands and the Moluccas. The Astrolabe returned to Marseille on 25 March 1829.
