Sergent Super Dorade Information, Review, Specs

Sailing Performance & Handling

The Super Dorade is characterized by a relatively heavy displacement for its size and a traditional hull form that prioritizes stability over raw speed. Featuring a moderate beam and a hull that often utilized a hard chine—a signature of Sergent's early designs—the boat tracks with remarkable consistency even in choppy coastal conditions. While it may not possess the light-air agility of modern sportboats, it excels when the breeze freshens, maintaining a balanced helm and a reassuringly stiff posture.

The vessel was typically produced in two underwater configurations: a single fin keel or a twin-keel (biquille) version. The twin-keel variant was particularly popular in regions with high tidal ranges, such as Brittany, as it allowed the boat to dry out upright on sandy bottoms. Performance-wise, the single keel version offers superior pointing ability and reduced drag, making it the preferred choice for sailors in the Mediterranean. Handlers often note that the boat feels "bigger" than its 21 feet, a sensation derived from its high freeboard and substantial laminate thickness, which damps the motion of the sea effectively.

Interior Comfort & Variations

For a vessel of its vintage and size, the Super Dorade offers a functional and surprisingly spacious cabin. The interior layout generally follows a classic four-berth arrangement: a V-berth in the bow and two lateral settee berths in the main salon. Given the boat's beam, the cabin provides sitting headroom for most adults, though standing room is not possible. Storage is integrated beneath the berths, reflecting its intended use for multi-day coastal hops rather than just day sailing.

Materials used in the interior were typical of the 1960s and 70s, featuring functional fiberglass liners accented by wooden trim and bulkheads. The "Super" designation distinguished it from its predecessor by adding a more substantial coachroof, which significantly increased the interior volume and light. While the standard Super Dorade was the most common, variations existed in the finish levels, with some later models featuring more extensive teak or mahogany woodwork, depending on the specific production run at the CNSO yard in Bon-Encontre.

Known Issues & Buyer’s Checklist

Prospective owners of a Super Dorade must account for the vessel's age, as most hulls are now over fifty years old. A primary concern is the integrity of the deck-to-hull joint, which in some early GRP models was prone to minor leaking if the mechanical fasteners or sealants had degraded. Additionally, the following areas require close inspection:

• Osmosis: While CNSO was known for thick, robust laminates, early polyester resins are susceptible to osmotic blistering. A moisture meter test on the hull is recommended.
• Compression Post: The mast is deck-stepped; ensure the supporting bulkhead or compression post beneath the deck remains structurally sound and has not succumbed to rot or compression fatigue.
• Keel Bolts: For fin-keel models, the condition of the keel bolts and the internal grid structure should be verified, as decades of hard grounding can stress these points.
• Chainplates: Check for signs of water ingress around the chainplates, which can compromise the plywood bulkheads they are often through-bolted to.

Community & Resources

The Super Dorade enjoys a cult-like status in France, where it is remembered as the boat that introduced many families to the sea. While there is no longer a formal factory-backed association, the "Amis des CNSO" groups and various French heritage sailing forums remain active hubs for technical advice and restoration logs. Owners often share documentation regarding the original Sergent sail plans and rigging specifications, which are essential for those looking to maintain the boat's original sailing characteristics.

The Verdict

The Super Dorade is a classic example of "small boat, big heart" naval architecture, offering a level of seaworthiness that belies its modest dimensions.

Pros:

• Robust Construction: Thick GRP hulls that have stood the test of time.
• Coastal Versatility: The twin-keel option is ideal for tidal environments.
• Historical Charm: A true pioneer of the French yachting revolution.
• Affordability: An accessible entry point for sailors seeking a vintage cruiser with character.

Cons:

• Age-Related Maintenance: Requires diligent upkeep of seals, woodwork, and older rigging.
• Performance Limits: Not a competitive racer; can be sluggish in very light winds.
• Limited Headroom: Only sitting headroom is available in the cabin.
