Sailing Performance & Handling
The Chatam 60 is a heavy-displacement cruiser designed more for "momentum-based" passage-making than light-air agility. With a reported displacement in the region of 23,700 kg (over 52,000 lbs), the hull possesses significant inertia, which translates to a comfortable, sea-kindly motion in heavy weather. Owners and testers often highlight its "go-anywhere" tracking, aided by a twin-rudder configuration that maintains exceptional grip even when the boat is heeled.
The cutter rig is the standard sail plan, providing a versatile array of gear for varying wind strengths. Typically, this includes a large 115 m² genoa and a self-tacking staysail of roughly 30 m², allowing the crew to downshift quickly as conditions deteriorate. Under power, it is not uncommon to find the Chatam 60 equipped with twin diesel engines (such as dual 75hp Yanmar units), a rare feature in monohulls that provides both redundancy for remote expeditions and superior maneuverability in tight quarters when the centerboard is raised. While its Sail Area/Displacement ratio suggests a moderate performer in light winds, the Chatam 60 excels in "tradewind" conditions where its hull length and stability allow it to maintain high average speeds over long distances.
Interior Comfort & Variations
The interior of the Chatam 60 is defined by the "Deck Saloon" philosophy, featuring a raised seating area that provides panoramic views of the horizon—a critical feature for both watch-keeping in cold climates and overall onboard morale during long voyages. The vessel's 5.18-meter beam allows for an expansive living space that typically accommodates three large cabins and a dedicated workshop area in the bow.
As a part of the larger Chatam family, which includes the 33, 37, 43, 47, and 50 models, the 60-foot version offers the highest degree of customization. Most iterations feature a massive aft owner’s suite with a private head and desk, reflecting the boat's role as a primary residence for "sea-steading" or professional expeditions. Insulation is a hallmark of the Caroff design; these boats are often fitted with thick foam cores and multiple heating systems (such as Dickinson or Eberspacher units) to ensure the interior remains habitable in Arctic or Antarctic conditions.
Popular Mentions & Media
The Chatam 60 occupies a respected niche in the French "Grand Voyage" community. Its design is frequently compared to the Fleur Australe, the famous expedition vessel of Philippe Poupon, which shares the philosophy of a protected, insulated wheelhouse and a rugged aluminum hull for high-latitude work. While the Chatam 60 lacks a single "star" media presence, it is a staple of French nautical literature concerning "amateur construction" and professional expedition planning, frequently cited as a benchmark for what a dedicated metal cruiser should be.
Known Issues & Buyer’s Checklist
Prospective buyers must approach a used Chatam 60 with a focus on its unique metal construction and mechanical complexity.
- Galvanic Corrosion: As an aluminum vessel, the primary concern is the integrity of the hull. A thorough ultrasonic hull thickness test is mandatory to check for pitting, particularly in the bilge areas and around the through-hull fittings.
- Centerboard Mechanism: The "integral dérive" (swing keel) relies on a heavy-duty hydraulic or manual lifting system. The pivot pin and lifting cables/rams are high-wear items that require inspection for play or corrosion.
- Insulation Integrity: While designed to be well-insulated, poorly executed amateur interior finishes can lead to condensation traps between the hull and the lining, potentially causing hidden oxidation or mold.
- Complex Systems: Because many Chatam 60s are fitted with "high-autonomy" gear—including twin engines, generators, watermakers, and multiple heating systems—the electrical and plumbing systems are significantly more complex than a standard yacht. A survey should specifically audit the wiring for "orphaned" systems from previous owners.
Community & Resources
The primary hub for technical data and owner support for this model is the Association des Propriétaires de Plans Caroff (APPC). This group serves as a technical wiki for owners of Chatam, Ile de Disko, and Sterwen designs, providing invaluable insights into the specific building techniques and structural modifications used during the construction of these vessels.
The Verdict
Pros:
- Extreme Draft Versatility: The 1.1m minimum draft is extraordinary for a 60-foot yacht, allowing entry into lagoons and rivers.
- Rugged Durability: The 16mm aluminum bottom plate found on many builds offers peace of mind against submerged objects or ice.
- All-Weather Comfort: The insulated, enclosed wheelhouse allows for comfortable watch-keeping regardless of the outside temperature.
- Redundancy: Often built with twin engines and high fuel/water capacities for true self-sufficiency.
Cons:
- Heavy Handling: Not a "fun" boat for light-wind day sailing; it requires breeze to come alive.
- Maintenance Intensity: Aluminum hulls require constant vigilance regarding electrical grounding and sacrificial anodes.
- Custom Build Variance: As many are custom-finished, the quality of the interior and systems can vary wildly between individual boats.
