Westerly Sealord 39 Information, Review, Specs

Sailing Performance & Handling

The Sealord 39 is characterized by a powerful, stiff performance that thrives as the wind increases. With a displacement of approximately 18,500 lbs and a ballast ratio of roughly 43%, the boat is notably sea-kindly and stable in offshore conditions. According to technical data from the Westerly Owners Association, the hull features a moderate-depth fin keel and a partially balanced spade rudder on a solid stainless steel stock, a combination that provides precise handling and a surprisingly tight turning circle for a vessel of its volume.

Its Displacement/Length (D/L) ratio of approximately 241 places it firmly in the "moderate cruiser" category, though its sailing characteristics lean toward heavy-weather resilience rather than light-air agility. While the smaller Westerly Corsair 36—a sibling model often compared to the Sealord—is known for its superior performance in light winds, the Sealord is praised by owners for its ability to "revel in the rough," maintaining a steady gait and manageable helm even when pushed hard in squally conditions. Most models were rigged as masthead sloops, though a ketch version was offered to provide a more divided sail plan for short-handed crews.

Interior Comfort & Variations

The interior of the Sealord 39 was a masterclass in mid-80s yacht design, offering a three-cabin layout that could accommodate up to ten people in a pinch, though it is optimized for a family or two couples. The hallmark of the design is the massive aft owner's stateroom, accessed via a walkthrough that typically houses the engine compartment and a sea berth or workshop area. This aft cabin includes a large double berth, an en-suite head, and sufficient headroom to avoid the cramped feeling common in center-cockpit designs of that era.

The main saloon features two settee berths and a large fixed dining table with integrated bottle stowage. Standard joinery was finished in high-quality teak-faced marine plywood, a hallmark of British craftsmanship that remains a point of pride for current owners. The forward section contains a V-berth guest cabin and a second head, providing excellent privacy for guests. A key variation in the hull’s lineage is the Oceanlord 41, which utilized the same basic hull mould but added approximately 15 inches to the stern to create a "sugar-scoop" bathing platform and a slightly enlarged aft stateroom, reflecting the industry's shift toward easier water access.

Popular Mentions & Media

The Sealord 39 has maintained a low-profile but respected presence in cruising literature and media. One of the most notable modern accounts of the boat’s offshore capabilities was featured in Yachting Monthly, documenting the voyage of a Sealord named Lordship. The account details the vessel's journey through the Caribbean and its resilience during a difficult passage to Haiti, reinforcing the model's reputation as a legitimate "world-girding" cruiser capable of handling unpredictable tropical conditions and remote island navigation.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Sealord 39 with a technical checklist focused on the "Westerly specific" age-related issues common to the 1980s fleet.

• Headlining "Droop": Like almost all Westerlys of this era, the foam backing on the interior vinyl headlining eventually disintegrates, causing the material to sag. This is a labor-intensive cosmetic repair that often involves replacing the panels entirely.
• Engine Power: Early models were fitted with the 36hp Volvo MD17D, while later versions often featured the 28hp Volvo 2003. Many owners find the 28hp unit slightly underpowered for a boat of this displacement in a head sea, making the 42hp turbocharged 2003T a highly desirable upgrade for buyers.
• Hull Composition: Boats built before 1985 typically used orthophthalic resins and are more susceptible to osmotic blistering. Post-1985 hulls shifted to isophthalic gelcoats, which significantly improved moisture resistance.
• Structural Bulkheads: Inspection of the bond between the main bulkheads and the hull is critical. Some reports on owner forums mention a small gap forming at the sole level over decades of hard use, which may require re-tabbing to ensure structural rigidity.

Community & Resources

The primary hub for technical support is the Westerly Owners Association, one of the largest and most active owner groups in the world. Their technical "Wiki" provides exhaustive documentation on the Sealord 39, including original brochures, wiring diagrams, and specific maintenance guides for the Ed Dubois range.

The Verdict

The Westerly Sealord 39 remains a premier choice for sailors seeking a robust, center-cockpit cruiser with genuine blue-water pedigree and "big boat" comfort.

Pros:

• Exceptional heavy-weather stability and sea-kindliness.
• Massive interior volume with a true owner's aft stateroom.
• High-quality British build standards and legendary teak joinery.
• Extensive support from a dedicated owner association.

Cons:

• Requires significant wind to "wake up" the hull; not a light-air specialist.
• Inevitability of headlining failure if not already replaced.
• Standard Volvo 2003 engine can feel underpowered in heavy conditions.
