Lanaverre L17 Information, Review, Specs

Sailing Performance & Handling

The L17 is defined by its light displacement—approximately 355kg to 450kg depending on the specific ballast configuration—which categorizes it as an ultralight sailer. Its hull geometry, featuring a relatively narrow beam of 1.86 meters and a sharp entry, allows it to perform well in light to moderate air, conditions where heavier cruisers of this length often struggle. The fractional sloop rig is a hallmark of the design, intentionally chosen to reduce the size of the headsails. This makes the boat exceptionally easy to tack and manage single-handedly, a feature highlighted in technical retrospectives by Bateaux.com.

On the water, the L17 feels more like a stabilized dinghy than a traditional keelboat. Because it was often delivered as a swing-keel (lifting keel) variant, it possesses a shallow minimum draft of roughly 0.20 meters, allowing it to be beached or sailed into thin-water estuaries. However, its low righting moment means that in heavy gusts, the boat requires active mainsheet management; it is stiff for its size but can feel "flighty" compared to heavier-displacement micro-boats like the British Leisure 17. Owners frequently note that while the boat can plane under optimal conditions with a spinnaker, its primary strength is as a secure, predictable coastal sailer for day-trips.

Interior Comfort & Variations

The "L17" and its predecessor, the "510," share the same hull but often differ in their deck moldings and cabin arrangements. The interior is a minimalist "cuddy" style, typically offering two full-length V-berths in the bow. Headroom is significantly restricted, as is expected for a 17-foot vessel, but the cabin provides enough dry stowage and shelter for a weekend trip for two adults.

Variations of the model exist primarily in the cabin window configuration and hatch design. Early 510 models often featured a smaller coachroof with one or two portholes per side, whereas later L17 versions produced under Yachting France sometimes featured elongated window strips and a slightly revised companionway. The construction is solid GRP (Glass Reinforced Plastic), and while the interior lacks a dedicated galley or head, the cockpit is surprisingly deep and spacious, often cited as more comfortable than many 20-foot boats due to the ergonomic placement of the coamings.

Known Issues & Buyer’s Checklist

Prospective buyers should focus on the specific mechanical and structural points common to the Lanaverre/Yachting France era of construction.

• Keel Pivot and Cable: For lifting-keel versions, the pivot bolt and the lifting cable are the most critical points of failure. Corrosion in the centerboard trunk can lead to a jammed keel or significant "clunking" while underway.
• Deck Delamination: Like many GRP boats of the 1970s, the L17 may suffer from soft spots in the deck core, particularly around the mast step and the chainplates. This is usually caused by moisture ingress through improperly sealed deck hardware.
• Rudder Gudgeons: The hardware connecting the transom-hung rudder is known to work loose over decades of use. Inspect the transom for stress cracks around these mounting points.
• Window Seals: The acrylic windows are often secured with older rubber gaskets or simple sealant that degrades over time, leading to leaks that can damage the interior cushions and wood trim.

Community & Resources

The L17 and 510 have a dedicated following in Europe, particularly in France and Germany. Technical support and historical documentation, including original brochures, are largely preserved by the ASPRO L17 & 510 (Association des Propriétaires de L17). While the brand no longer exists, the universality of its rig components means that most hardware can be serviced with off-the-shelf parts from modern marine suppliers.

The Verdict

The Lanaverre L17 is an ideal entry-level sailer for those who want the security of a cabin without the maintenance costs and logistical hurdles of a large yacht.

Pros:

• Excellent light-air performance due to the Christian Maury hull design.
• Highly towable and easy to launch from a standard trailer.
• The fractional rig makes it one of the easiest boats in its class to sail solo.

Cons:

• Minimal interior amenities; strictly for "camping-style" cruising.
• Light displacement makes it less suitable for high-wind, choppy offshore conditions.
• Lifting keel mechanisms require regular maintenance to prevent seizing.
