L 29 Information, Review, Specs

Sailing Performance & Handling

The L 29 is often described as an "overgrown H-Boat," a compliment that highlights its balanced helm and predictable tracking. With a displacement-to-length ratio that leans toward the moderate side of performance cruising, the boat excels in light to medium airs where its generous sail area and efficient fin keel allow it to outpace many contemporaries of the same era. The fractional rig is a hallmark of Groop’s designs, providing sailors with significant control over mainsail shape, which is essential for depowering the boat as the breeze freshens.

On the water, the L 29 is noted for its stiffness, a result of a high ballast ratio that keeps the boat upright and maintains a clean flow over the spade rudder. According to archival technical summaries from the Hans Groop Design Portfolio, the hull's narrow beam relative to modern standards contributes to its exceptional upwind pointing ability, though it does lack the initial stability found in wider, more modern hulls. In a seaway, the L 29 exhibits a classic motion, slicing through chop rather than slamming, which reduces crew fatigue during long coastal passages.

Interior Comfort & Variations

For a vessel of 29 feet designed in the late 1970s, the L 29 offers a functional and surprisingly warm interior, characterized by the extensive use of teak and high-quality joinery typical of Finnish builders. The layout is traditional: a V-berth forward, a central salon with two longitudinal settees that double as sea berths, and a small galley located near the companionway. Headroom is approximately 1.75 meters (5'9"), which is adequate for the era but may feel restrictive for taller sailors.

While the standard L 29 layout was the most common, the hull served as the foundation for the L 30 and the earlier Lohi 28. The L 30 variant often featured an updated deck mold with a more streamlined coachroof and minor modifications to the interior cabinetry to increase storage. In all versions, the emphasis remains on "compact cruising," where every centimeter of space is utilized, including storage bins behind the settee cushions and a dedicated (though tight) head compartment between the salon and the forward cabin.

Known Issues & Buyer’s Checklist

When inspecting an L 29, the primary concern is the age of its original systems and the specifics of its sandwich construction. Potential buyers should focus on the following high-signal areas:

• Deck Core Integrity: Like many Nordic boats of this vintage, the L 29 utilizes a balsa-core sandwich construction for the decks. Moisture ingress around stanchion bases, chainplates, or the mast step can lead to core delamination. Buyers should feel for "spongy" areas and look for stress cracks in the gelcoat.
• Engine Service Life: Many original L 29s were fitted with Volvo Penta MD7A or small Yanmar diesel engines. Given their age, these units may be approaching the end of their reliable service life. Check for signs of manifold corrosion and verify the availability of spare parts.
• Keel-to-Hull Joint: While the L 29 is stoutly built, the keel bolts and the fiberglass around the keel sump should be inspected for "smile" cracks or signs of movement, which can occur after a hard grounding.
• Osmotic Blistering: While Lohi had a generally good reputation for layup quality, boats kept in warmer waters or those with original gelcoat may show signs of osmotic blistering. A moisture meter test on the hull below the waterline is recommended.

Community & Resources

Owners of the L 29 benefit from a shared community with other Hans Groop designs. The H-Boat associations in Finland and Germany often serve as a secondary resource for L 29 owners due to the similarities in rigging and design philosophy. Technical data and historical context are frequently maintained by the Finnish sailing community through outlets like the Finnish Sailing and Boating Federation, though much of the deep technical documentation remains in Finnish or Swedish.

The Verdict

The L 29 is an elegant, high-quality cruiser-racer that offers a sophisticated sailing experience for those who value performance and classic lines over sheer interior volume.

Pros:

• Superior Handling: Exceptional upwind performance and a very balanced helm.
• Build Quality: Solid Nordic construction with high-grade interior woodwork.
• Aesthetics: A timeless, low-profile silhouette that stands out among modern high-freeboard designs.

Cons:

• Internal Volume: Narrow beam results in less living space than modern 29-footers.
• Limited Headroom: Taller sailors will find the cabin height restrictive.
• Aging Systems: Expect to invest in modernizing electronics, sails, and potentially the auxiliary engine.
