The Arak 42 is a seminal example of the mid-1970s French school of naval architecture, specifically representing the emergence of the "dériveur intégral" (integral centerboarder) as a viable blue-water cruising platform. Designed by the prolific Jean-Marie Finot (Groupe Finot), the Arak 42 was primarily conceived for construction in aluminum, a material choice that emphasized ruggedness and longevity for high-latitude or long-distance exploration. While often built by specialized yards such as Metalu or occasionally by skilled amateur builders under license, the design remains a hallmark of Finot’s early philosophy: a wide beam for stability, a shallow draft for versatility, and a hull form capable of surprising speeds when reaching.

Sailing Performance & Handling
The Arak 42 is characterized by its significant beam-to-length ratio, a trait that Jean-Marie Finot helped popularize to provide stability without the need for a deep, heavy fixed keel. As an integral centerboarder, the boat carries its ballast—typically lead—low in the hull, allowing the centerboard to be retracted entirely into the hull. According to historical design notes from Finot-Conq, this configuration allows for a minimum draft of roughly 0.90 meters, enabling the vessel to enter shallow lagoons or be "beached" on flat tidal sands.
Under sail, the Arak 42 is most comfortable on a reach or a run. The flat hull sections and wide stern reduce the tendency to broach in heavy following seas, a common critique of more traditional narrow-transom designs of the 1970s. However, because the centerboard is a non-ballasted foil used primarily for lateral resistance, the boat lacks the ultimate righting moment of a deep-keeled racer. Upwind performance is respectable in moderate breezes, but as the wind increases, the Arak 42 prefers to be sailed "fat" rather than pinched to maintain its momentum. Tracking is generally reliable due to the long waterline, though the helm can become heavy if the boat is over-canvased.
Interior Comfort & Variations
The interior of the Arak 42 reflects the utilitarian and seaworthy priorities of its era. With a beam approaching 4 meters, the vessel offers an expansive main saloon for a 42-foot boat of its vintage. Most configurations feature a large "U" or "L" shaped settee surrounding a central table, often situated directly over the centerboard trunk, which is cleverly integrated into the cabinetry.
Typical layouts included a dedicated, forward-facing navigation station—essential for the pre-GPS era—and a functional galley designed for use at sea. As a boat often built for long-term cruising, storage is prioritized, with deep lockers and under-sole compartments. The Arak 42 was a direct predecessor and sibling to the Seal 42, which shared much of its DNA but featured refined interior arrangements. Another close relative is the Reveille 40, another Finot aluminum design that utilized similar hull geometries. Because many Arak 42s were finished by different yards or owners, wood species and joinery quality vary significantly from one hull to another, ranging from functional marine plywood to high-end teak or mahogany veneers.
Known Issues & Buyer’s Checklist
Prospective buyers of an Arak 42 must approach the hull with the specific scrutiny required for 50-year-old aluminum vessels. While the material is incredibly strong, it is susceptible to specific failure modes if neglected.
- Galvanic Corrosion (Electrolysis): The most critical area of inspection is the hull's integrity. Any historical "patchwork" or pitting near the waterline or around through-hulls suggests a failure in the electrical bonding system or improper shore-power isolation. A professional ultrasonic hull thickness test is mandatory.
- Centerboard Pivot and Trunk: The pivot pin and the internal lifting mechanism are wear items. Owners on technical forums often note that the trunk can accumulate marine growth or silt if the boat is left stationary in shallow water, which can jam the board. The bushings should be checked for play to avoid "keel clank" while at anchor.
- Insulation and Sweat: 1970s aluminum boats often used early-generation foam insulation. If this has pulled away from the hull or was never installed, the boat will suffer from significant condensation ("sweating") in cold climates, which can lead to hidden corrosion behind cabinetry.
- Rigging Loads: Ensure the chainplates, which are typically welded or bolted to aluminum knees, show no signs of distortion or hairline cracking. Given the age, the standing rigging should be replaced if its history is unverified.
Community & Resources
Support for the Arak 42 is largely found within the broader community of Finot design enthusiasts and aluminum boat owners. The Association des Propriétaires de Plans Finot remains a primary repository for technical drawings and historical data. While no single-model "Arak 42 Club" exists, the boat is frequently discussed within French offshore cruising circles and "Dériveur Intégral" technical groups, where the legacy of Jean-Marie Finot’s aluminum pioneers is still celebrated.
The Verdict
The Arak 42 is a specialist’s yacht, designed for the sailor who values the ability to explore shallow estuaries as much as the ability to cross oceans. It is a robust, no-nonsense platform that prioritizes safety and versatility over modern dockside luxury.
Pros:
- Extreme Versatility: The lifting keel allows access to anchorages and harbors closed to almost all other 42-foot monohulls.
- Structural Integrity: If properly maintained, an aluminum hull offers superior impact resistance compared to fiberglass.
- Proven Pedigree: Designed by one of the 20th century’s most respected naval architects.
Cons:
- Maintenance Intensive: Requires strict adherence to electrical isolation and anode replacement to prevent corrosion.
- Vintage Systems: Most examples will require significant electrical and plumbing overhauls to meet modern standards.
- Limited Upwind Performance: Will not point as high or move as efficiently into the wind as a modern fixed-keel cruiser.
