CNB 87 Information, Review, Specs

Sailing Performance & Handling

The CNB 87 is characterized by the sea-kindliness and balanced helm typical of German Frers’ designs from the late 1980s. With a displacement that favors momentum and stability over the light-air agility of modern racing yachts, the 87 utilizes an aluminum hull to provide immense structural rigidity, allowing the rig to stay tensioned and efficient even in heavy offshore conditions. Most iterations, such as the well-known hull Archimedes, were delivered with a ketch rig, which provides a versatile sail plan of approximately 365 square meters. This configuration allows a small crew to "split the tabs," reducing individual sail sizes for easier handling while maintaining a powerful drive through the water.

Under power, the yacht typically relies on a heavy-duty Mercedes-Benz 280Hp diesel engine, often achieving a cruising speed of 10 knots and a maximum speed of 12 knots. The hull's deep-V entry and generous beam of 6.8 meters contribute to excellent tracking and reduced slamming in a head sea. While technical data for this custom build varies by hull, the high ballast-to-displacement ratio ensures a stiff, upright ride that prioritizes the comfort of guests during long ocean passages.

Interior Comfort & Variations

True to the heritage of CNB Yachts, the interior of the 87 is a testament to the shipyard’s "lute-maker" level of craftsmanship. The layout is typically centered around a raised deck saloon, a signature feature that provides panoramic views and floods the living area with natural light. The use of high-grade teak or cherry joinery is common, creating a warm, classic atmosphere that contrasts with the industrial strength of the aluminum exterior.

The standard configuration for this model accommodates six guests in three en-suite staterooms, with a significant emphasis placed on the owner’s suite, which often spans the full beam or occupies a private section of the aft quarters. Separate crew accommodations for four members are located either forward or aft of the galley and navigation station, ensuring a distinct separation of service and guest areas. Because the CNB 87 was a custom project, interior variations exist; some owners opted for additional Pullman berths or a larger galley to facilitate extended charter operations.

Popular Mentions & Media

The CNB 87 gained significant recognition within the superyacht community through the hull Archimedes (later renamed), which became a staple of the Mediterranean and Caribbean charter circuits. SuperYacht Times has historically tracked these custom CNB builds, noting their longevity and the high frequency with which they undergo substantial refits to maintain modern technological standards. The 87-foot bracket is often cited as the "sweet spot" for CNB, sitting between their smaller semi-custom sisters and their massive 100-foot-plus custom commissions like Grand Bleu Vintage.

Known Issues & Buyer’s Checklist

Purchasing a legacy aluminum superyacht like the CNB 87 requires a specialized technical survey focused on the unique properties of the material and the age of the systems.

• Galvanic Corrosion: As an aluminum vessel, the primary concern is electrolysis. Buyers must ensure the sacrificial anodes have been regularly maintained and that there is no "stray current" from faulty shore power connections or uninsulated electrical components that could cause pitting in the hull.
• Teak Deck Longevity: Many 1990-era CNBs feature original teak decks that were screwed and glued. After three decades, the remaining thickness of the teak and the integrity of the caulking are critical inspection points, as full replacement on a vessel of this scale is a six-figure undertaking.
• Hydraulic Systems: The CNB 87 relies heavily on hydraulics for furling, winches, and the bow thruster. Potential buyers should inspect the hydraulic lines for leaks and the power pack for pressure consistency, as these systems are central to managing the yacht with a reduced crew.
• Engine & Generator Hours: Given their history as long-range cruisers, these yachts often carry high hours on their Mercedes or Cummins main engines. A fluid analysis and a borescope inspection are recommended to assess the internal condition of these older, albeit robust, powerplants.

Community & Resources

Owners of custom CNB yachts often find technical support through the manufacturer’s legacy department or via specialized superyacht management firms. While there is no dedicated "CNB 87" class association due to its custom nature, the CNB Rendez-Vous events occasionally feature these classic builds alongside newer semi-custom models like the CNB 76 or CNB 88. Technical documentation for these older aluminum hulls is often maintained at the Bordeaux shipyard or available through the original designers at Frers Naval Architecture.

The Verdict

The CNB 87 is a blue-water thoroughbred that offers a level of structural security and custom luxury rarely found in modern production yachts. It is an ideal platform for a world circumnavigation or high-end chartering, provided the owner is prepared for the maintenance rigors of a large, complex aluminum vessel.

Pros:

• Exceptional structural integrity from the aluminum hull.
• Timeless design by German Frers with balanced sailing characteristics.
• Large interior volume with a light-filled deck saloon.
• Proven transoceanic capability and charter pedigree.

Cons:

• Requires vigilant monitoring for galvanic corrosion.
• High maintenance costs associated with aged superyacht systems.
• Ketch rig adds complexity to sail handling and standing rigging maintenance.
