description
Lagoon 420 - The great travel catamaran, ready to cast off the moorings
Signed Lagoon, the 420 vintage 2008 has established itself as one of the references of the family offshore cruise catamaran. Generous volumes, assumed travel career and follow-up maintenance: this unit under the France flag, offered at €265,000 including tax, is aimed at crews who want to go far without giving up comfort.
Construction and marine qualities
GRP Hull and Bridge - Fiberglass, 12.61 m in length for 7.53 m in width and only 1.30 m of draft: proportions that open the most discreet anchorages while offering a stable platform of 12,800 kg. The rigging is served by a full-beat horn incidence (2025) mainsail, a genoa on reel, Lazy Bag and Lazy Jack, rail and mainsail, winches including an electric one. The standing rigging is new (2026).
Motorization and fittings
Two Yanmar 4JH4TCE diesel in Sail Drive (4,400 and 4,200 hours) provide 7 cruising knots for about 2 l/h, and up to 11 knots. With 600 l of fuel and 700 l of water supplemented by a watermaker, the autonomy is up to the program. Inside, 4 cabins and 8 beds, 4 marine toilets, convertible square, card table, equipped kitchen (fridge, stove, oven, water heater). Capacity of 12 people.
