Design Brief & Intent
Lindenberg conceived the Wavelength 24 primarily as a racing boat that could be easily trailer-launched, yet stiff enough to handle severe coastal chop. While other manufacturers of the era attempted to pack family-cruising accommodations into 24-foot hulls, Schock and Lindenberg prioritized performance, dedicating the vast majority of the boat’s footprint to a massive, ergonomic cockpit. The interior, consequently, is a study in minimalist weight-saving.
With a cabin headroom of just 51 inches, the space below is designed for sheltering crew or quick overnighting rather than extended living. The original interior configuration consists of a double V-berth in the bow (typically utilized for sail storage), two opposing straight settee berths, and a minimal galley with a pull-out two-burner stove and a sink. Structural weight is minimized through marine-grade plywood bulkheads and unadorned fiberglass surfaces, reflecting a build designed entirely around the racecourse.
Variations & Configurations
Over its production lifecycle, the Wavelength 24 underwent several notable changes, most clearly defined by the hull number series. Pre-hull #100 boats built between 1982 and 1990 feature the classic interior layout with traditional wooden bulkheads, wood stringers, and a standard V-berth configuration. When W.D. Schock revived the boat in 2005—starting production at hull #100—they introduced sweeping updates. The primary cabin bulkhead was relocated 20 inches forward to further expand the already generous cockpit, and the interior was modernized with light, hammock-style bunks designed to suspend crew comfortably while providing immediate, unobstructed access to the storage lockers below.
While a standard 4.5-foot deep fin keel designed by Lars Bergstrom remains the benchmark for racing performance, the later production run also offered an optional wing keel for shoal-draft optimization. The rig is classically configured as a tall masthead sloop, though minor fractional variants exist in custom configurations. Propulsion is standardly managed via a small outboard motor, typically 3 to 6 horsepower, mounted in a cockpit well or on a transom bracket.
Sailing Performance & Handling
Under sail, the Wavelength 24 is a spirited, highly responsive machine that punches far above its weight class. A sail area-to-displacement ratio of 25.01 highlights an incredibly powerful rig that allows the boat to accelerate in light air that leaves heavier boats becalmed. The displacement-to-length ratio of 132.83 confirms its ultra-light, easily driven hull form, enabling the boat to plane readily downwind under a spinnaker.
Despite this light displacement, a high ballast-to-displacement ratio of 44.00 percent, supported by a heavy lead fin keel, ensures the boat remains surprisingly stiff and holds its canvas well when sailing upwind. However, its low comfort ratio of 9.66 indicates a highly active, motion-heavy ride in rough chop, requiring an active crew to manage the helm and trim. With a capsize screening formula of 2.65, the boat is clearly optimized as a coastal or lake racer-daysailer rather than a heavy-weather offshore voyager, demanding prompt reefing when wind speeds climb into the high teens.
Known Issues & Structural Triage
For prospective buyers and current restorers, several areas of the Wavelength 24 require systematic inspection. Foremost is the keel attachment structure. To distribute the immense loads of the deep lead keel, Schock installed an aluminum floor grid bonded directly to the bottom of the hull. Over decades of hard racing, this bond can fail or deteriorate, particularly if saltwater has been left to stand in the bilge, leading to galvanic corrosion of the aluminum plate.
Additionally, deck core saturation remains a common vulnerability. Like many production boats of the 1980s, the deck utilizes a balsa and plywood core which can rot if water penetrates through poorly sealed deck organizers, chainplates, or aftermarket hardware. The balanced spade rudder, constructed with a steel internal backbone and high-density filler encased in fiberglass, is also prone to water ingress, which can lead to internal rust and swelling of the rudder blade over time.
Modernization & Upgrades
Contemporary owners frequently focus their refit budgets on weight reduction and deck layout modernization. Upgrading the deck hardware is a common priority, replacing the original, heavy line clutches with modern high-load clutches, and installing low-friction rings and modern mainsheet traveler systems. The running rigging is universally upgraded to low-stretch Dyneema to maximize control over the powerful rig.
Due to the boat's light weight and minimalist needs, electric propulsion has become a highly popular modification. Replacing old, heavy, and fuel-smelling two-stroke outboards with clean, lightweight electric outboards significantly improves the cabin air quality while providing more than enough thrust to move the lightweight hull in and out of the marina. Finally, original canvas hammock bunks and interior storage pouches are easily replaced with modern marine-grade fabrics to refresh the cabin's aesthetic.
The Verdict
The Wavelength 24 remains one of the finest sleeper-performance boats of its era, offering exceptional speed-for-dollar value on the used market. For sailors who prioritize pure sailing sensations, tactical responsiveness, and the convenience of trailerability, this Paul Lindenberg classic is a compelling alternative to more common one-design racers. It is not, and never was, a family cruiser, but as a club racer or high-speed daysailer, its capabilities remain transitionally evergreen and undeniably formidable.
Pros
- Exceptional light-air performance and off-wind planing capability.
- Stiff and stable upwind due to a high ballast-to-displacement ratio.
- Highly trailerable and easy to launch from standard boat ramps.
- Oversized, highly ergonomic cockpit designed for efficient crew work.
- Strong build quality from W.D. Schock, including an innovative aluminum floor grid.
Cons
- Extremely limited interior headroom and Spartan accommodations.
- Low comfort ratio results in a highly active and motion-heavy ride in rough seas.
- High capsize screening ratio limits its safe use to coastal and inland waters.
- Aluminum floor grid is vulnerable to galvanic corrosion if neglected in wet bilges.
- Rudder is prone to water penetration and internal structural degradation.
