a Mouette (Seagull), a ship of 227 tons, outfitted as a schooner brig. Why the choice of a Clipper? Because it was built to transport perishable produce as quickly as possible, thanks to its slimmer shape, this speed also allowing it to overcome the monsoon. Outfitted as a schooner brig, it was easy to handle and efficient for coastal shipping. The Mouette casted off on 3 June 1862 for the Far East under the command of his son, Gustave with Emile on board. Arriving in Saigon in October 1862, the 2 brothers founded in November the company Denis Frères (today the Denis Group).
