Rhea 850 Timonier

The Rhea 850 Timonier is a retro-inspired, robustly built motoryacht that blends the purposeful aesthetic of a classic French Atlantic workboat with premium, modern cruising comforts. A cut above other mass-produced French cruisers in this size range, this versatile pocket-trawler features a heavy semi-displacement hull with a deep protective skeg, ensuring a stable, dry, and reassuring ride even in challenging coastal conditions. Below deck, high-quality woodwork designed by Olivier Flahault transforms the vessel into a highly capable all-weather weekender, offering comfortable accommodation for up to four guests, a fully equipped galley, and a private heads compartment. Powered by twin inboard diesels and enhanced by a factory-fitted bow thruster, this well-mannered motoryacht is easily handled in tight harbours.

With her current owners since 2020 the Rhea 850 MIRANDA has proven to be a comfortable and reliable cruiser. Her owners have enjoyed cruising the waters of the Clyde and out to the Western Isles.
