Couach is a French yacht and shipyard brand based in the Arcachon area of southwestern France. The company traces its origins to 1897, when Albert Couach began making marine engines, and later expanded into boat and yacht construction. Today, Couach builds custom yachts and professional vessels, including patrol and defense boats.
Origins and shipyard
Couach’s history begins in Arcachon, France, where Albert Couach created marine engines in 1897 and established the company’s first business base. The family firm later moved into boatbuilding under Guy Couach, who developed series-built boats and helped define the brand’s modern direction. Sources also place the shipyard’s manufacturing activity in Gujan-Mestras, near Arcachon, and note later expansion into a technical base in the Mediterranean. Over time, the company shifted from engine making to a broader naval shipyard identity.
Range and reputation
Couach is known for building custom yachts as well as professional craft, especially patrol, surveillance, and military vessels. Reported hull lengths range from about 11 metres to 50 metres, and the brand has also been associated with large luxury yachts and superyachts. The shipyard’s reputation rests on composite construction, seakeeping, and long experience in high-performance hulls. Its catalogue has included models such as the Couach 2800 Open, 3000 Fly, and 3700 Fly.
