Guy Couach 1501 CL

Guy Couach 1501 CL: French marine excellence, made reliable, modernized, and ready for the season

A flagship offshore dayboat from the well-known Arcachon shipyard, the Guy Couach 1501 CL is known for its robust polyester construction, its excellent handling in Mediterranean chop, and its generous living comfort. This unit stands out with a very user-friendly layout featuring 3 cabins and 2 bathrooms with electric toilets, complemented by an independent crew cabin at the front. Offering 6 to 7 true berths, it includes an owner suite with a double berth, two guest cabins with twin beds that can be converted into double berths, as well as a spacious saloon whose upholstery has been completely redone in high-end white Ultraleather.

In terms of machinery and propulsion, this vessel has benefited from a meticulous and documented maintenance history for its two GM 6V71TI 485 hp inline-shaft engines, totaling about 2,800 running hours. Key areas have seen major investment: complete renewal of the starboard exhaust line in April 2024 (new turbocharger, elbow, hoses, and new fasteners), stainless-steel port elbow, and a full overhaul of the cooling system (open coolers cleaned and serviced, and turbines replaced in 2024). Inspection during anode replacement in June 2026 confirms that the heat exchangers are perfectly healthy, with no scale or deposits. The transmission has been made more reliable since 2020 with the installation of modern, no-maintenance PSS-type packing seals, and the replacement of Hydrolube bushings on 55 mm shafts, while the four-blade propellers have been optimized. Fuel is closely monitored (10 micron filtration and systematic biocide treatment), and the full 2026 overhaul has just been completed (oil change Pro Diesel SAE40, JMP turbines, and new anodes).

Range and exterior layouts are the other major strengths of this unit. The 24V/220V electrical system has been upgraded with a Victron MultiPlus 3000VA/70A charger/inverter combined unit connected to a BMV-700 controller, a second Dolphin 40A charger, a bank of 4 service batteries 180 Ah (2024), 2 engine batteries 180 Ah (2023), charge balancers (2021), and a Fischer Panda generator with a dedicated 70 Ah battery (2022). On deck, circulation is smooth and safe: a new 2025 sliding rear aluminum glazed window, refurbished Opacmare hydraulic gangway (2022 grating and custom PVC cover 2023), an electric Lofrans Tigres 1500W windlass with 60 m of new chain (2022), and an extended aft platform with structural underwater reinforcements in epoxy composite. All canvas covers and upholstery have been carefully renewed: reinforced 316L stainless-steel flybridge bimini frame, windscreen cover, forward sunpad in Sunbrella (2023), and new cockpit upholstery in imitation leather (March 2026).

Life on board focuses on comfort, with all lighting converted to LED, a fully equipped galley including a new large refrigerator/freezer unit (2026), a second front-opening fridge, dual cooking options (gas and induction), a microwave, an outdoor gas plancha, and a multimedia setup (Fusion radio and 3 televisions). For navigation, the wheelhouse and flybridge feature a Raymarine electronics package (E120W and E90W displays, DSM30 sounder with bronze transducer), a Raymarine Evolution autopilot (2019), an Ocean VHF radio, a refurbished bow thruster, and renewed hydraulic flaps.

Commercial transparency: Meticulously maintained by a demanding owner with a complete set of invoices, this unit comes out of a spring service period including wash, polishing, and antifouling carried out in April 2026. Offered at a consistent and realistic price of 119,000 EUR VAT included, it is a rare, turnkey opportunity for enthusiasts of character-rich motor yachts looking for large, comfortable living spaces and proven, trouble-free machinery with no immediate work required.
