RM 1180 Information, Review, Specs

Sailing Performance & Handling

The performance profile of the RM 1180 is defined by its high power-to-weight ratio and a hull shape that borrows heavily from Class40 racing lines. The use of plywood-epoxy construction allows for a hull that is significantly lighter and stiffer than traditional solid laminate fiberglass, which, when paired with a powerful fractional rig, results in exceptional light-wind performance. In a comprehensive sea trial, Yachting Monthly noted that the boat's wide, chined hull provides immense form stability, allowing it to carry full sail longer than more narrow-bodied competitors.

The boat is typically offered with three keel configurations: a single performance fin keel, a lifting keel for shallow-draft versatility, or RM’s signature twin-keel (bilge keel) setup. While the twin-keel version is slightly slower upwind due to increased wetted surface, it allows the boat to dry out upright on a tide—a major advantage for cruisers in Atlantic Europe. Steering is exceptionally communicative thanks to the twin-rudder configuration, which maintains a tenacious grip on the water even when the boat is pressed hard on a reach. Owners frequently report that the 1180 "planes" with surprising ease for a cruising yacht once the true wind speed exceeds 18 knots on a broad reach.

Interior Comfort & Variations

Inside, the RM 1180 breaks from the dark, cavernous feel of traditional sailboats, opting instead for a "loft-style" aesthetic. The most striking feature is the forward-facing panoramic window, which floods the saloon with natural light and allows the watch-keeper to monitor the horizon from the warmth of the navigation station. Because the hull is built of wood rather than from a mold, there is no inner GRP liner; this not only saves weight but also provides superior thermal and acoustic insulation.

The standard layout features three cabins: a spacious master cabin in the V-berth and two aft cabins. A popular variation, often seen in hulls destined for serious offshore work, replaces one of the aft cabins with a dedicated technical room or "garage" for stowage of sails, tools, and a watermaker. The furniture is often finished in light-colored woods or white lacquers to emphasize the sense of space. While the interior is modern and functional, RM Yachts emphasizes that the structural bulkheads are bonded directly to the hull, creating a monocoque structure that eliminates the "creaks and groans" common in production boats with floating interiors.

Popular Mentions & Media

The RM 1180 received immediate critical acclaim upon its release, being nominated for the prestigious European Yacht of the Year award in the "Performance Cruiser" category in 2020. It has been a frequent subject of praise in French nautical publications like Voiles et Voiliers, where it is often cited as the benchmark for modern plywood-epoxy construction. Its cultural footprint is strongest among "fast-cruising" enthusiasts in Europe, who often document their voyages on social media platforms, highlighting the boat's ability to maintain high average speeds during Atlantic crossings.

Known Issues & Buyer’s Checklist

While the RM 1180 is a robustly engineered vessel, its unique construction requires specific maintenance considerations:

• Paint Integrity: Unlike GRP boats with gelcoat, the 1180 is painted. The epoxy-plywood hull is impervious to osmosis, but the exterior paint serves as the primary barrier against UV and moisture. Any deep gouges must be repaired immediately to prevent moisture from entering the timber core.
• Deck-to-Hull Joint: The RM 1180 utilizes a GRP deck joined to a plywood hull. Buyers should inspect the stainless steel rub-rail and the joint for any signs of stress or sealant failure, particularly near the stanchion bases.
• Keel Attachment: For twin-keel versions, the internal "Kevlar-reinforced" grid should be inspected for any signs of movement, though these boats are famously over-engineered in this area to allow for regular drying out.
• Rudder Bearings: Given the twin-rudder setup and the high loads generated by the wide beam, the self-aligning bearings should be checked for play or "notchness" during a survey.

Community & Resources

Owners of the RM 1180 are supported by a passionate and technically savvy community. The RM Forains (an association of RM owners) is the primary hub for technical exchange, offering a wealth of knowledge on maintenance specific to CP Epoxy construction. While based in France, the group is the definitive resource for anyone seeking performance data or refurbishment advice. Additionally, the manufacturer, now under the stewardship of the Grand Large Yachting group, provides high-level support and maintains a history of the technical drawings for individual hulls.

The Verdict

The RM 1180 is a specialist’s tool—a high-performance, aesthetically striking cruiser that prioritizes structural integrity and speed over the maximum cabin volume found in mass-production yachts.

Pros:

• Exceptional stiffness and weight-to-strength ratio due to plywood-epoxy build.
• Industry-leading visibility from the saloon thanks to the panoramic window.
• Versatile keel options, including the ability to dry out on twin keels.
• Modern, racing-inspired hull that excels on offshore reaches.

Cons:

• Requires more diligent exterior maintenance (paint) than traditional fiberglass yachts.
• Wide beam can make finding slips in older, narrower marinas challenging.
• The "industrial" loft interior may feel sparse to those accustomed to traditional wood joinery.
