S&S PJ-40 Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the PJ-40 are defined by its significant displacement and high ballast-to-displacement ratio (approximately 42%). Weighing in at roughly 19,000 lbs with a heavy fin keel and a skeg-hung rudder, the boat exhibits a "freight train" momentum that makes it exceptionally sea-kindly in heavy weather. According to technical data from the S&S Swan Association, the vessel features a Displacement/Length (D/L) ratio of 364, placing it firmly in the "heavy cruiser" category. While this mass requires a stiff breeze to overcome initial inertia, once established, the PJ-40 tracks with remarkable stability, resisting the "hobby-horsing" common in lighter modern designs.

Handling is precise but physical. As an IOR-influenced design, the boat has a relatively narrow beam (10' 8") compared to its length, which aids in its legendary upwind performance. It "goes to weather like a witch," as noted by various owner accounts, maintaining high pointing angles even in choppy conditions. However, the relatively modest Sail Area/Displacement ratio of 15.99 suggests it can be underpowered in light airs, often requiring a large 150% genoa to maintain competitive speeds. Off the wind, the pinched stern of the early 1970s design can make the boat somewhat prone to rolling in a following sea, though the skeg-hung rudder provides a level of directional control and protection that modern spade rudders lack.

Interior Comfort & Variations

The interior of the PJ-40 reflects the high-standard joinery of Nautor’s early production. The layout is a classic offshore arrangement designed to function both at the dock and under heel. It typically features six berths: a double V-berth in the forward cabin, two settee berths in the main salon, and two single berths in a dedicated aft cabin area. The use of hand-rubbed teak throughout creates a warm, traditional atmosphere that is a significant departure from the fiberglass-heavy interiors of contemporary production boats.

A key variation to note is that while the majority of hulls were standard fin-keel sloops, a few were produced with an optional retractable centerboard, designed for sailors in shallower regions like the Chesapeake Bay or the Bahamas. The galley is traditionally located on the starboard side, featuring an L-shaped configuration that allows the cook to brace themselves while underway. Headroom is generous for a 40-foot boat of this vintage, though the cabin feels narrower than modern yachts due to the hull's significant tumblehome.

Popular Mentions & Media

The PJ-40 is frequently cited in "Classic Boat" retrospectives as one of the most iconic cruisers of the early Nautor era. It has gained a "cult" status among purists who participate in the Baltic Rendezvous and other classic yacht regattas. Its media footprint is largely technical and historical, appearing in design archives as a pivotal bridge between the wooden yacht era of S&S and the modern fiberglass dominance of the late 20th century.

Known Issues & Buyer’s Checklist

Prospective buyers of a PJ-40 should approach the vessel with an understanding of its age, focusing on several high-signal technical areas:

• Deck Coring: Like many yachts of the 1970s, the PJ-40 utilizes a balsa-cored deck. Moisture intrusion around stanchions, winches, and the mast step can lead to core rot, requiring expensive "peel and replace" repairs.
• Rudder Skeg Integrity: The connection point between the skeg and the hull is a known stress area. Inspect for "smile" cracks or signs of movement that could indicate structural fatigue in the fiberglass layup.
• Original Engine Exhaust: Many PJ-40s were originally fitted with the Volvo Penta MD2B. These engines are now at the end of their service life, and the original exhaust systems often suffer from internal corrosion that can lead to water back-flooding into the manifold.
• Wiring and Plumbing: The original 12V DC systems were ungrounded and used early-generation plastic-coated wiring that may now be brittle. Upgrading to modern ABYC-compliant wiring is a common requirement for insurance.

Community & Resources

The primary hub for technical support is the S&S Swan Association, which maintains an exhaustive database of original designer drawings, plumbing diagrams, and wiring schematics for the PJ-40. This group is instrumental in helping owners source original-style hardware and maintain the vessel’s historical value.

The Verdict

The Palmer Johnson 40 is a "sailor’s sailboat," designed for those who value structural integrity and heavy-weather capability over interior volume and light-air speed. It remains one of the finest examples of the Sparkman & Stephens legacy.

Pros:

• Exceptional build quality and "over-engineered" hull strength.
• Elegant, timeless aesthetics that command respect in any marina.
• Superior upwind performance and sea-kindly motion in a blow.

Cons:

• Sluggish performance in light winds (under 8-10 knots).
• High maintenance requirements typical of 50-year-old teak and systems.
• Narrow interior and pinched stern compared to modern 40-footers.
