Design Brief & Intent
The Windjammer 34 was designed for the serious, self-sufficient blue-water cruiser who prioritizes safety, ultimate seaworthiness, and payload capacity over outright speed. By stretching the hull lines of the traditional 32-footer to over 34 feet on deck, the designer created a boat with a flatter run aft and a significantly longer waterline. Unlike standard production cruisers of its era, which were increasingly built for light-wind coastal hops, the Windjammer 34 is a true high-latitude, deep-sea voyager.
The interior design reflects its blue-water pedigree, with layouts heavy on solid teak and mahogany joinery. The cabinetry, bulkheads, and cabin sole are engineered to survive knockdowns, with massive structural handholds strategically placed throughout the interior. Storage is vast and meticulously divided, taking advantage of the hull's deep bilge and substantial hull beam. The cabin is cozy, warm, and highly functional at sea, featuring a secure offshore galley, a dedicated navigation station, and comfortable sea berths designed to keep off-watch crew safe and snug in a seaway.
Variations & Configurations
Because of the semi-custom, low-volume nature of the Windjammer 34’s production run, layouts and rigs vary based on the original owner’s specifications. The hull was most commonly rigged as a cutter or a ketch. The cutter rig offers a highly versatile, easily managed sail plan for single-handed or double-handed crews, allowing the forestay to carry a staysail while the primary headsail is flown from a robust bowsprit. The ketch rig splits the sail area into smaller, highly manageable pieces, providing a lower center of effort and a greater variety of sail combinations, which is ideal for heavy-weather tacking or balancing the helm.
While draft is uniform at five feet, supporting the full-keel configuration, variations are primarily found in the deck molds and interior layout executions. Earlier hulls were sold to owners as bare shells to be finished by home builders or independent shipyards. Later models featured a fully molded fiberglass deck constructed by Windjammer Yachts, which minimized the exterior wood maintenance compared to the completely custom teak deck over fiberglass combinations seen on some early examples.
Sailing Performance & Handling
With a displacement of 20,200 pounds and a modest sail area to displacement ratio of 15.1, the Windjammer 34 is a classic heavy-displacement cruiser. It is not a light-air racer and will feel sluggish in gentle breezes of under ten knots. However, when the wind rises, the yacht truly begins to shine. Under a press of sail, the massive hull form provides immense stability. This is mathematically supported by its displacement to length ratio of 382.67, confirming its position in the ultra-heavy category.
Handling in a seaway is exceptionally smooth. The boat has a comforting motion comfort ratio of 41.38, which means its motion in heavy chop is slow, predictable, and highly seakindly, significantly reducing crew fatigue over long passages. The capsize screening formula of 1.64 is well below the safe ocean racing ceiling of 2.0, providing excellent peace of mind for bluewater crossings. Additionally, the ballast to displacement ratio of 39.6 percent guarantees a highly stiff boat that stands up well to a blow and carries its momentum through waves. At the helm, the transom-hung rudder delivers solid, mechanical feedback, and when properly trimmed, the Windjammer 34 tracks exceptionally well, making it easy to steer by windvane or autopilot for days on end.
Market Snapshot & Economics
Finding a Windjammer 34 on the brokerage market requires patience, as production was highly limited compared to mass-produced cruisers. However, for those who appreciate the robust construction of Westsails but desire the slightly better tracking and interior space of a 34-foot hull, this model commands a respectful premium among connoisseurs.
The economics of purchasing a Windjammer 34 are closely tied to its construction history. If looking at a home-completed kit, buyers must evaluate the quality of the plumbing, wiring, and carpentry, as amateur execution can vary wildly. Conversely, factory-finished boats or those completed by World Cruiser Yacht Company maintain high resale value. Because these boats were built in the late 1970s and early 1980s, owners should anticipate the typical refit costs of any classic yacht: repowering older diesel engines, replacing original standing rigging, and inspecting traditional deck joints.
Known Issues & Triage
While the solid-fiberglass hull laminated by Crystaliner is generally bulletproof and highly resistant to structural issues, the Windjammer 34 is subject to several vintage-boat vulnerabilities.
- Teak Deck Overlays: Some owners opted for teak decks laid over fiberglass. Over decades, the hundreds of screws holding the teak in place can back out or lose their sealant, allowing water to penetrate the fiberglass deck core. Triage requires a thorough moisture inspection, and in worst-case scenarios, the teak must be removed, the core re-formed, and the deck refinished with non-skid.
- Osmotic Blistering: The polyester resins used in the late 1970s are prone to typical osmotic blistering. While rarely a structural concern on hulls this thick, severe blistering will require a bottom job involving peeling, drying, and applying an epoxy barrier coat.
- Chainplate Crevice Corrosion: The external chainplates are subject to heavy strain and crevice corrosion. They must be regularly unbolted, inspected, and polished or replaced to prevent rig failure.
- Wood Boomkins and Bowsprits: Traditional wooden spars require constant varnishing to prevent rot. Many owners replace these with custom stainless steel boomkin hoops and bowsprits to reduce maintenance.
Modernization & Upgrades
Modern owners of the Windjammer 34 are increasingly focusing on upgrades that enhance self-sufficiency and comfort during extended off-grid cruising.
- Lithium Battery Upgrades: Replacing old lead-acid battery banks with modern Lithium Iron Phosphate (LiFePO4) chemistry is a highly common upgrade. This allows cruisers to run modern refrigeration, watermakers, and induction cooktops without relying on a generator.
- Rig and Deck Hardware: Upgrading original winches to self-tailing models and routing key halyards and control lines back to the safety of the cockpit dramatically improves the boat's short-handed handling.
- Repowering: Many of these boats were originally equipped with underpowered or noisy diesels. Upgrading to a modern, freshwater-cooled marine diesel engine (such as a Beta Marine or Yanmar) provides quiet, reliable auxiliary power and better fuel efficiency.
- Electric Propulsion: For coastal cruisers, the heavy displacement of the hull makes electric propulsion a viable alternative, provided the vessel is fitted with an extensive solar array on a custom stern arch.
The Verdict
The Windjammer 34 is an absolute masterpiece of traditional, heavy-displacement boatbuilding, offering unparalleled safety, comfort, and stability for offshore blue-water cruising. While it will never win light-wind races, its ability to keep its crew safe and comfortable in the worst ocean conditions makes it one of the finest pocket-sized passage makers of its era.
