Design Brief & Intent
The core mission of the Lanaverre 590 was to merge the planing potential of a light-displacement dinghy with the stability and utility of a cabin-cruiser. At just under twenty feet, it features a rounded hull form with an upright, full bow and a pinched waterline that flares out to broad, flat sections aft. This shape provides significant volume forward to prevent nose-diving when driven hard, while allowing the boat to plane easily when sailing off the wind.
Compared to heavy, traditional pocket cruisers of the era like the Muscadet, the Lanaverre 590 is explicitly light and athletic. The tiny low-profile cabin house prioritizes aerodynamics and low weight over interior headroom. Below deck, the accommodations are basic and tightly packaged, offering V-berths that can sleep two adults in overnight "camping" style, though the space is more frequently utilized for storing sails, safety gear, and provisions. The focus is squarely on the cockpit, which occupies nearly half the deck length, emphasizing that the 590 is designed for active outdoor sailing rather than liveboard comfort.
Variations & Configurations
Over its long production run, the Lanaverre 590 saw several structural evolutions and shipyard changes. The most notable interior and cockpit variations concern the seating configuration. Early models from the 1960s were built with rounded cockpit tanks, directly reminiscent of the 420 and 470 dinghies. While these rounded tanks made it easy for hiking crew to roll over the side, they were uncomfortable for casual sitting. In 1972, Lanaverre modified the tooling to introduce flat-topped, square cockpit benches with a small coaming. This change dramatically improved ergonomic comfort for family cruising and day-sailing without altering the hull’s underwater profile.
The underbody configuration relies on a clever stub-keel and centerboard arrangement. The shallow fixed stub keel encapsulates 309 pounds of steel fragments embedded in polyester resin. Housed within this stub is a heavy, retractable stainless steel centerboard weighing approximately 65 pounds. This combination yields a minimum draft of 1.64 feet, allowing the boat to sit flat on sandy beaches during low tide or load easily onto a road trailer, and a maximum draft of 4.10 feet when the board is fully lowered for upwind performance.
In the 1980s, the molds were acquired by the Brunet-France yard, which attempted to civilize the design. The Brunet version featured a taller, more bulbous coachroof with a forward-facing hatch, a slightly deeper stub keel, and an additional 110 pounds of ballast to increase righting moment. However, these modifications increased weight and compromised the light, responsive handling of Maury’s original design, making the Brunet variant a rare and less sought-after model on the used market.
Sailing Performance & Handling
Under sail, the Lanaverre 590 behaves like a scaled-up, high-performance dinghy rather than a conventional keelboat. With a displacement of only 1,213 pounds and a generous fractional sloop rig delivering 185 square feet of working sail area, the boat boasts a high Sail Area-to-Displacement ratio of 26.02. This makes it incredibly lively in light air, accelerates rapidly out of tacks, and enables the hull to break free of its bow wave and plane in moderate breeze.
Its stability characteristics are dynamic rather than ultimate. The ballast-to-displacement ratio of 25.47% is modest for a cabin boat, and its Capsize Screening Ratio of 2.52 indicates that the hull relies heavily on form stability and crew weight to stay upright. The original racing class rules actually permitted the use of a trapeze for the crew 3, testifying to its sporty character. While the 374 pounds of total ballast in the keel and centerboard prevent the boat from capsizing as easily as an unballasted dinghy, the helmsman must remain active, and the mainsheet must be kept at hand in gusty conditions. Upwind, the deep centerboard provides excellent lift, but the shallow hull can slam in a choppy head sea if not kept heel-compensated and driven fast.
Known Issues & Triage
For buyers looking at vintage Lanaverre 590s, age-related fiberglass and structural issues require careful inspection. The primary engineering weakness centers on the coachroof structure on early models. Because the original design lacked an interior compression post, the cabin top was designed to support the mast step through fiberglass reinforcement alone. Decades of rig tension, particularly in boats that have been upgraded to modern, highly tensioned fractional rigs, often cause the coachroof to sag. This structural deflection distorts the cabin trunk and prevents the companionway slide from operating smoothly. The accepted class repair is to retrofit an aluminum or stainless steel compression post directly under the mast step down to the top of the centerboard trunk.
The centerboard and its casing are also common failure points. The stainless steel centerboard is prone to warping if the boat has been repeatedly grounded hard on rocky bottoms, which can cause the board to jam inside the trunk. The pivot pin can wear out over time, leading to clanking noises under sail and potential leaks around the pin housing. Repairing this requires lifting the boat off its trailer, dropping the board, and replacing the pivot bushings and seals. Additionally, because the encapsulated ballast in the stub keel consists of scrap steel mixed with polyester resin, any deep gouges in the bottom laminate can allow water to penetrate the ballast cavity, resulting in internal rust expansion that can crack the outer keel fiberglass.
Modernization & Upgrades
Due to an active owner's association and a passionate racing fleet in Europe, many Lanaverre 590s have undergone extensive modernizations. To handle the modern loads of high-aspect sails, veteran owners routinely upgrade the standing rigging. The original 50-centimeter spreaders are frequently replaced with wider 80-centimeter spreaders to improve mast column support, and the lower shroud chainplates are often reinforced and moved inward or aft to clear the overlapping genoa. Wood spars from early production runs are almost universally replaced with anodized aluminum sections.
For auxiliary propulsion, the boat was traditionally powered by a 2 to 5 horsepower gas outboard mounted on a transom bracket. Today, the lightweight nature of the hull makes it an ideal candidate for electric propulsion conversions. Owners are increasingly replacing heavy gasoline outboards with lightweight, clean electric pods or tiller-mounted electric outboards, which easily drive the hull to its theoretical hull speed while keeping the transom light and preserving the boat’s sailing trim.
The Verdict
The Lanaverre 590 is a brilliant piece of French design heritage that offers an intoxicating blend of dinghy-like speed and pocket-cruiser utility for the minimalist sailor. It is not a blue-water passage maker or a comfortable family camper, but as a spirited, easily trailerable dayboat for exploring shallow estuaries, inland lakes, and tidal bays, it remains tough to beat.
Pros
- Exceptional light-air performance and planing capability off the wind.
- Extremely shallow draft with the centerboard up, allowing easy beaching and effortless trailering.
- Active and supportive class association that keeps spare parts and tuning guides accessible.
- Low maintenance costs and simple systems that make DIY restoration highly manageable.
- Limited ultimate stability; requires active heel management and crew weight shifting in heavy air.
- Coachroof is prone to compression sagging on models without a retrofitted compression post.
- Tiny cabin with negligible headroom, suitable only for basic gear storage or spartan weekend camping.
- Exposed to hull slamming and wet rides when sailing into a steep head chop.
