From the Mini 6.50 #868 to the Class40 #196, the full racing career at Alternative Sailing
Guillaume L'Hostis, nicknamed “Junior”, is from Fouesnant. He started sailing Optimists at age 6, then raced Lasers in high school at the performance sailing center, followed by offshore racing training at the Institut Nautique de Bretagne. He joined Alternative Sailing (La Trinité-sur-Mer) as an apprentice for two years, then was hired full-time. He spent eight years with the team, including serving as base manager in Martinique until 2022. Since May 2024, he has been the official skipper of the Class40 Alternative Sailing / Constructions du Belon.
Mini 6.50: the formative years
Before the Class40, Guillaume honed his skills in the Mini 6.50 class aboard the 868 Alternative Sailing - Constructions du Belon. In 2018, he finished 2nd in the Duo Concarneau with Tanguy Bouroullec. In 2019, he completed the Mini-Transat in 11th place out of 65 boats in the standard series. In 2021, he reunited with Bouroullec on the Pogo Foiler 969: victory at the Mini Fastnet in proto class, after a tight duel with the 1019 Teamwork.
