Chassiron RF Information, Review, Specs

The RF hull served as the foundation for several distinct models within the Chassiron family. The most common sibling is the Chassiron TME (Trans-Mondial Export), which was optimized for long-distance voyaging with a Ketch rig and specific interior modifications for offshore life. Other siblings built on similar lines include the Chassiron GT (Grand Tourisme), which focused on coastal cruising luxury, and the smaller Chassiron Junior, a 7-meter version that retained the same aesthetic DNA. The RF remains the most "purist" iteration of the design, often found with a sloop rig and a focus on balanced, predictable sailing.

Sailing Performance & Handling

The Chassiron RF is characterized by its heavy displacement and long keel, features that dictate a very specific "sea-kindly" behavior. With a displacement-to-length ratio that leans heavily toward the "heavy cruiser" category, the boat does not accelerate quickly in light air; however, it excels in maintaining momentum once established. Owners frequently report that the RF feels "planted" in a seaway, with the long keel providing excellent directional stability and reducing the tendency to "hunt" or wander when sailing downwind.

Because of its traditional hull shape, the RF tracks exceptionally well, making it a favorite for solo sailors or those relying on older wind-vane steering systems. The motion through the water is noticeably softer than modern flat-bottomed boats, with the V-shaped entry slicing through chop rather than slamming into it. While the boat is not a weatherly performer—its pointing ability is limited compared to modern fin-keel designs—it offers a sense of security in heavy weather that is rarely matched in its size class. In winds above 15 knots, the RF comes into its own, holding its canvas longer than lighter competitors and maintaining a steady heel.

Interior Comfort & Variations

The interior of the Chassiron RF is a masterclass in classic French joinery. Eschewing the modern trend of modular plastic inserts, the Richard shipyard utilized extensive amounts of solid mahogany and teak, creating a cabin that feels more like a traditional wooden ship than a fiberglass production boat. The standard layout features a classic V-berth forward, followed by a heads compartment that spans the width of the boat. The main salon typically includes two longitudinal settees with a central folding table, which can be converted into additional berths.

One of the defining characteristics of the RF variant is its functional galley and dedicated navigation station, both located near the companionway for ease of use while underway. Headroom is generous for a vessel of this era, usually exceeding 1.85 meters (6 feet) in the main cabin. Variation among siblings is significant: while the RF often maintains a more open, airy feel, the TME (Trans-Mondial) variant frequently features more cabinetry and storage lockers at the expense of open floor space, designed to secure provisions for months at sea.

Known Issues & Buyer’s Checklist

Prospective buyers of a Chassiron RF must account for the age of these vessels, as most were launched between 1965 and 1978. While the hulls are robust, they are susceptible to several "classic boat" ailments:

• Teak Deck Integration: Many Chassiron models were delivered with teak decks screwed directly into the fiberglass laminate. Over decades, these screws can back out or allow water to penetrate the core. Buyers should check for soft spots in the deck and signs of water ingress in the headliner below.
• Osmotic Blistering: While the hulls are thick enough that osmosis rarely structural, older Chassiron hulls frequently exhibit "wicking" or small blisters. A moisture meter test is essential to determine if a full peel and epoxy treatment is required.
• Rudder Bushings and Skeg: The RF features a protected rudder, but the bushings at the heel of the skeg can wear over time, leading to vibration or "play" in the steering. This is a difficult area to service while the boat is in the water.
• Chainplates: Given the boat’s age, the original stainless steel chainplates may be reaching the end of their fatigue life. Inspectors should look for "bleeding" or crevice corrosion where the plates pass through the deck.

Community & Resources

The Chassiron community is primarily centered in France, but its members are scattered across the globe due to the boat's blue-water reputation. The Association des Propriétaires de Chassiron serves as the definitive technical archive for the model, providing original blueprints, sail plans, and a register of surviving hulls. This group is an invaluable resource for sourcing specific replacement parts or advice on restoring the traditional wooden interiors.

The Verdict

The Chassiron RF is a "blue-water classic" that offers a level of build quality and sea-kindliness rarely seen in the 30-foot range today. While it is too slow for racing and requires more maintenance than a modern plastic cruiser, its aesthetic appeal and rugged construction make it an ideal choice for the traditionalist.

Pros

• Exceptional heavy-weather stability and tracking.
• High-quality traditional joinery and "ship-like" interior feel.
• Extremely robust fiberglass hull construction.
• Strong owner community and historical pedigree.

Cons

• Poor light-wind performance and limited pointing ability.
• High maintenance requirements for exterior wood and teak decks.
• Slow maneuvers in tight marinas due to the long keel.
• Likely requires modernization of original plumbing and electrical systems.
