Design Brief & Intent 1
Herb David designed the Lancer 39 to serve as a versatile coastal cruiser and a highly liveaboard-friendly platform. During an era when major competitors like Catalina and Hunter dominated the recreational market with standard aft-cockpit and center-cockpit designs, Lancer carved out a niche for owners who wanted protection from the elements in cooler or highly variable climates. The core design brief centered on maximizing usable interior volume and providing panoramic visibility from within the cabin—features traditionally reserved for powerboats.
The interior of the Lancer 39 reflects this dual-purpose mission. Rather than forcing crew members down into a dark, subterranean cabin, the boat features a raised salon or deck-gallery layout. Large windows surround the pilothouse, flooding the living spaces with natural light and allowing the helmsman or crew to monitor the horizon while sheltered from wind and spray. Lancer constructed the interior using a structural fiberglass modular liner system, which was then trimmed with teak and mahogany joinery 7. While the finish and joinery of these production boats were geared toward utility and value rather than ultra-luxury cabinetry, the sheer volume, exceptional headroom, and clever layout options made them highly competitive liveaboards for couples and small families.
Variations & Configurations
While the Lancer 39 was built with a standardized fiberglass hull and deck, Lancer Yachts offered several configurations to suit different cruising styles. The standard rig was a simple and robust masthead sloop, which carried its sail plan lower than a fractional rig, minimizing heeling moments and simplifying sail handling for short-handed crews. Beneath the waterline, the boat was equipped with a fixed fin keel drawing 5.67 feet, paired with a skeg-mounted rudder. This configuration provided a balance of lift under sail and directional stability under power.
Drivetrain configurations represent the most notable division among surviving hulls. Most Lancer 39s were delivered with a single inboard diesel engine, typically a mid-range Perkins, Yanmar, or Westerbeke unit, putting out between 50 and 85 horsepower. However, catering to the power-oriented buyer, Lancer produced a small number of hulls equipped with twin-diesel configurations. These twin-screw installations essentially transformed the vessel into a highly maneuverable power catamaran-style drivetrain within a monohull shape, delivering exceptional motoring speeds and redundant "get-home" security at the expense of increased maintenance and engine-room clutter.
Interior layouts also varied, with the "tri-cabin" configuration being highly prized. This layout featured a forward V-berth, a raised midships salon with a linear or U-shaped galley, and a completely private aft master cabin accessed via a walkway. This arrangement provided excellent separation of space and privacy, a layout rarely seen in traditional monohulls under 40 feet.
Sailing Performance & Handling
The sailing characteristics of the Lancer 39 are heavily dictated by its hybrid hull design. It is not a light-air racer; the flatter, wider hull sections required to support high-speed motoring create a larger wetted surface area, which generates noticeable drag in light conditions. With a displacement of 16,000 pounds and a waterline length of 33.5 feet, the displacement-to-length ratio of 189.99 places the boat in the light-medium displacement category. This relatively low ratio for a 39-footer indicates that the hull shape is highly efficient, allowing the boat to reach its theoretical hull speed of 7.76 knots quickly under both sail and power.
The ballast-to-displacement ratio of 21.88% is lower than that of traditional offshore cruisers, which typically hover near 30% to 40%. This means the Lancer 39 is relatively tender initially. It relies on its generous 12-foot beam and flat bottom to provide form stability as the boat heels. Once the boat settles onto its shoulder in a stiff breeze, it stiffens up and tracks predictably.
At the helm, the skeg-mounted rudder provides heavy, steady, and reassuring feedback, especially when running downwind or traversing confused coastal chop. With a capsize screening ratio of 1.91, the hull form possesses a safe beam-to-displacement profile, falling safely below the ocean racing limit of 2.0. The comfort ratio of 25.70 indicates that the motion in a seaway is quicker and more active than a heavy-displacement double-ender, though highly tolerable for coastal passages.
The true brilliance of Herb David's design is experienced when "motor-sailing". By running the diesel engine at low revolutions while keeping the sails sheeted in, the Lancer 39 achieves a highly efficient cruising state. The sails stabilize the hull, virtually eliminating rolling in a beam sea, while the engine provides the forward thrust needed to maintain high speeds directly through calms or headwinds.
Market Snapshot & Economics
Today, the Lancer 39 occupies a highly specific value-oriented segment of the brokerage market. Because Lancer Yachts ceased operations in the mid-1980s and the model had a brief production run, these vessels are relatively scarce. They generally trade at a significant discount compared to more traditional cruisers of the same era, such as the Pearson 39 or Tartan 37, making them highly attractive to budget-conscious buyers seeking maximum interior volume and livability.
The refit economics of a Lancer 39 require careful calculations. Because the boat was built as a mid-tier production yacht, the market value of a fully restored model rarely matches the cumulative cost of major structural, electrical, and mechanical upgrades. Consequently, buyers should prioritize hulls that have already undergone modern repowering and major system overhauls. Fortunately, because Lancer utilized standard off-the-shelf deck hardware and mechanical components from major manufacturers like Perkins, Lewmar, and Teleflex, sourcing replacement parts for the rig and drivetrain remains relatively straightforward.
Known Issues & Triage
Prospective owners of a Lancer 39 must look past the vessel's spacious interior to inspect several critical structural and mechanical areas.
- Engine Mounts and Stringers: Because these boats were often fitted with larger, heavier, and higher-horsepower engines than typical sailboats, the fiberglass-encapsulated wood engine stringers are subjected to immense vibrational stress and torque. Inspectors should search for hairline cracks in the fiberglass skin of the stringers, which can allow oil and bilge water to penetrate and rot the wood core inside.
- Keel-to-Hull Joint: The Lancer 39 utilizes a bolt-on external ballast keel. Hulls that have been driven hard under power into steep head seas are prone to flexing at this joint. Grounding or prolonged stress can manifest as "the smile"—a visible hairline gap at the leading edge of the keel-hull joint. The keel bolts must be inspected for corrosion, and the backing plates inside the bilge should be checked for signs of crushing or structural stress in the surrounding laminate.
- Fuel Tank Corrosion: True to its motorsailer heritage, the Lancer 39 carries a larger fuel capacity than a standard sailing yacht of its length. The original aluminum fuel tanks are often located under the cabin sole or cockpit. Over time, exposure to trapped bilge water can lead to crevice corrosion. Inspectors should look for white, powdery pitting (aluminum oxide blooming) along the bottom corners of the tanks. Replacing these tanks is a labor-intensive project that often requires cutting away sections of the interior joinery or cabin sole.
- Deck Core Wetness: The decks are constructed using a balsa core sandwiched between layers of solid fiberglass. The stanchion bases, chainplates, handrails, and the wide borders of the raised pilothouse windows are highly susceptible to water intrusion if the original bedding compound has failed. Any soft spots or elevated moisture readings around these fittings require immediate re-bedding or core excavation to prevent structural rot.
Modernization & Upgrades
Modernizing a Lancer 39 can dramatically enhance its performance as a liveaboard and coastal cruiser.
- Electrical System Overhaul: The original 1980s electrical system, configured for basic lead-acid batteries, is woefully inadequate for modern cruising needs. Upgrading to a lithium-iron-phosphate (LiFePO4) house battery bank, paired with high-output alternators and smart regulators, allows owners to run refrigeration, watermakers, and even air conditioning without relying on a noisy diesel generator.
- Solar Integration: The flat roof of the raised pilothouse is an ideal platform for installing high-efficiency solar arrays. Rigid or semi-flexible solar panels can be mounted directly to the pilothouse roof, providing passive charging capabilities that align perfectly with the boat's high electrical demands during extended off-grid stays.
- Pilothouse Window Replacement: The large acrylic or safety glass windows of the raised cabin house are prone to crazing, scratching, and leaking. Replacing the old glazing with modern, UV-stabilized tempered glass or high-grade polycarbonate panels bedded in premium polyurethane elastomeric sealants is one of the most effective ways to restore structural integrity, stop cabin leaks, and dramatically improve visibility from the interior helm station.
- Repowering: For hulls equipped with aging or poorly maintained original Perkins diesels, repowering with a modern, clean-burning Yanmar or Beta Marine diesel engine is a common choice. A modern engine is lighter, significantly quieter, and more fuel-efficient, which helps offset the hull's inherent drag when under power alone.
The Verdict
The Lancer 39 is a highly functional, mission-specific cruising platform that appeals to practical sailors rather than traditional purists. It trades away the sleek lines, deep-heeling capabilities, and light-air agility of a classic sailboat in exchange for immense interior volume, panoramic visibility, and the ability to maintain comfortable transit speeds regardless of wind direction. For cruising couples looking for a comfortable, all-weather liveaboard boat for coastal waters, the Pacific Northwest, or the Great Lakes, it offers exceptional volume-per-foot and highly practical motor-sailing efficiency at an accessible price point.
