RM 900 Information, Review, Specs

Sailing Performance & Handling

The RM 900 is defined by its hard-chine hull, which provides a significant increase in form stability as the boat heels, allowing it to carry more sail area than many of its contemporaries. Most RM 900 units were configured as bilge-keelers (twin keels), a design choice that facilitates "beaching" or drying out in tidal harbors without the need for additional support. Despite the common misconception that twin keels sacrifice performance, the RM 900’s keels are high-aspect and efficient; in a vintage review by the French publication Voiles et Voiliers, the model was praised for its stiff, upright sailing characteristics and its ability to track reliably even in a following sea.

With a relatively high sail area-to-displacement ratio, the boat feels lively in light winds but truly comes alive when the breeze exceeds 15 knots. Because it uses a twin-rudder system on many hulls—a signature Lombard feature found on his larger designs like the RM 1050—the boat maintains exceptional grip on the water, even when pressed hard on a reach. Owners frequently report that the RM 900 handles more like a modern Class40 racer than a traditional cruiser, offering a tactile helm and predictable response.

Interior Comfort & Variations

The interior of the RM 900 was revolutionary for the early 90s, particularly regarding its use of natural light. The "panoramic" coachroof window, which has since become an RM Yachts trademark, provides a 180-degree view from the saloon, eliminating the "basement" feel typical of plywood or fiberglass yachts of that size. The layout is generally open-plan to maximize the sense of space, featuring a large forward berth that is integrated into the saloon, a functional L-shaped galley, and a dedicated navigation station.

As a boutique build, variations exist, but the most common configuration includes a double aft cabin on the port side and a large heads/storage area to starboard. The use of light-colored woods and white epoxy finishes reflects its French offshore racing heritage. The RM 900 was the middle child in a lineage that included the smaller RM 800 and the slightly larger, highly successful RM 1050. While the RM 800 was more of a coastal hopper, the RM 900 was the first in the range to be widely considered a legitimate cross-channel and coastal trekker with the tankage and storage required for multi-week voyages.

Known Issues & Buyer’s Checklist

The primary concern for any prospective RM 900 buyer is the integrity of the epoxy-plywood hull. While this construction method is incredibly strong and stiffer than solid GRP, it requires diligent maintenance.

• Keel Attachment Points: On bilge-keel versions, the stresses on the hull-to-keel joints are higher than on a single-keel boat. Check for any signs of "smile" cracks or movement in the epoxy fillets around the internal floors.
• Moisture Ingress: The "Achilles heel" of plywood boats is end-grain rot. Inspect areas where hardware has been through-bolted (stanchion bases, cleats) to ensure the epoxy seals have not been breached, allowing water to reach the wood core.
• Window Seals: The large forward-facing acrylic windows are prone to crazing and leaking over decades. Replacing these is a specialized job due to the curve of the coachroof.
• Rudder Bearings: Given the twin-rudder configuration, any play in the linkage can lead to a "heavy" or vibrating helm.

Community & Resources

The RM 900 is supported by a dedicated following, primarily centered around the Association des Propriétaires de RM (AvRM). This association serves as a vital technical repository for owners, offering guidance on the specific maintenance requirements of epoxy-plywood hulls and providing a network for sourcing replacement parts that are unique to the Fora Marine builds.

The Verdict

The RM 900 is a connoisseur’s yacht, offering a level of performance and architectural distinctiveness rarely found in the 30-foot cruiser market. It is an ideal vessel for sailors in tidal regions who refuse to sacrifice speed for the convenience of a shallow draft.

Pros:

• Exceptional Stability: Hard chines and twin keels offer a very safe, "flat" sailing experience.
• Visibility: The panoramic windows offer unparalleled light and situational awareness from the cabin.
• Beaching Capability: Can be dried out on its own keels, saving on haul-out costs and expanding cruising grounds.

Cons:

• Maintenance Intensity: Requires more vigilant inspection of the hull finish compared to standard fiberglass boats.
• Market Niche: Being a plywood/epoxy boat, resale may take longer as it requires a buyer who understands the construction method.
• Insulation: Early RM models can suffer from condensation issues in colder climates if not retrofitted with modern insulation.
