This is Gyptis, the replica of a Greek sewn boat from the 6th century BC. In: Gyptis: Sailing Replica of a 6th-century-BC Archaic Greek Sewn Boat, by Patrice Pomey, Pierre Poveda, The International Journal of Nautical Archaeology, Nr. 47, 1, 2018
Based on a find in Marseille, this boat was used as an archaeological experiment to study the technique of hull sewing and how such a boat sails. I have already explained the sewing technique here.

In Marseille, two archaic Greek shipwrecks were discovered in 1993 during excavations at the Place Jules Verne, entrusted to the nautical archaeology team of the Centre Camille Jullian. They are wrecks of boats built towards the end of the 6th century BC by the second generation of Greek colonists from Phocaea, who founded Massalia-Marseille around 600 BC, and located near the shore. These wrecks thus reflect the shipbuilding techniques used in Phocaea and in the Aegean during the Archaic period, namely the sewing of the hull, which the Greek settlers brought with them to Marseille.

The smaller wreck, Jules-Verne 9, was used for the replica. It is a coastal ship of about 10 m in length, which was used for coral fishing and was probably abandoned. As the archaeologists discovered during more than 50 test voyages, the Gyptis is a good sailor and well suited for the coastal regions. She sails well under winds up to Beaufort 5 and about 6 nautical miles offshore.
