Southerly 28 Information, Review, Specs

Sailing Performance & Handling

The defining characteristic of the Southerly 28 is its variable draft, which ranges from a mere 1’ 10” (0.56m) with the keel retracted to 4’ 10” (1.47m) when fully extended. This is achieved via a massive cast-iron swing keel housed within a heavy grounding plate. Unlike many modern light-displacement swing-keelers, the Southerly 28 is relatively heavy, with a displacement of approximately 6,950 lbs. This weight, combined with a ballast ratio of nearly 45%, gives the boat a surprisingly "big boat" feel in a seaway.

Under sail, the 28 is a steady, predictable performer rather than a racing machine. With the keel down, it tracks well and displays a high degree of initial stability. Owners frequently note that the boat handles chop with more grace than its 28-foot length suggests, largely due to the weight of the iron grounding plate positioned low in the hull. According to historical reviews in Yachting Monthly, the boat is best described as a "go-anywhere" cruiser that favors safety and versatility over high-pointing ability. When the keel is raised, the boat can be sailed downwind in very shallow water, though leeway increases significantly if one attempts to beat to windward without the foil deployed.

Interior Comfort & Variations

For a vessel under 30 feet, the Southerly 28 offers a layout that maximizes the "deck saloon" concept long before it became a standard industry term. The raised coachroof provides expansive windows, allowing a panoramic view from the interior—a rare luxury in the mid-1970s. The standard configuration typically includes a V-berth in the bow, a convertible dinette in the main saloon, and a compact galley.

A notable sibling to the 28 is the Southerly 95, which was developed as a direct evolution of this hull, offering a slightly modernized interior and refined deck molding. While most 28s were fitted with the standard tiller steering, some rare variants were equipped with an internal steering station, taking advantage of the visibility provided by the high windows. The use of warm teak joinery and heavy GRP moldings gives the cabin a robust, sheltered feel, though prospective buyers should note that headroom is approximately 6 feet in the main saloon but tapers off moving forward.

Known Issues & Buyer’s Checklist

The complexity of the Southerly 28's lifting mechanism is the primary area for technical scrutiny. Unlike a simple daggerboard, the Southerly's swing keel is a heavy structural component that requires regular maintenance.

• The Pivot Pin: The stainless steel pin upon which the keel swings is subject to wear over decades. If the keel "clunks" while at anchor or under sail, the pivot pin or the bushings may need replacement, a task that requires specialized lifting equipment.
• Keel Pennant & Winch: The wire or dyneema rope used to lift the keel should be inspected for fraying. The manual winch mechanism, usually located near the companionway or on the cabin sole, requires periodic lubrication to prevent seizing.
• Grounding Plate Corrosion: The cast iron grounding plate is the lowest point of the boat and is often exposed to salt water and abrasion from beaching. Buyers should check for significant "exfoliation" of the iron or signs that the sealant between the plate and the GRP hull has failed.
• Engine Access: Many 28s were originally powered by the BUKH 20 diesel engine. While these are exceptionally durable, parts are becoming increasingly expensive. The engine sits deep in the hull, and checking the stern gland or cooling hoses can be a challenge due to the constraints of the keel box.

Community & Resources

The most authoritative resource for technical data and historical documentation is the Southerly Owners Association. This organization maintains an extensive archive of original Northshore brochures, keel maintenance guides, and a community-driven database of hull-specific modifications. Because the Southerly 28 shares many design philosophies with its larger siblings, the association serves as a vital hub for sourcing discontinued parts for the lifting mechanisms.

The Verdict

The Southerly 28 is a specialist vessel that remains highly sought after by sailors who frequent tidal estuaries or shallow coastal regions. It is not the fastest boat in its class, but it is among the most versatile.

Pros

• Ultimate Versatility: The ability to navigate in less than two feet of water and sit upright on the beach.
• Robust Build: High ballast ratio and heavy-duty GRP construction.
• Visibility: The raised saloon offers excellent natural light and views compared to contemporary 1970s designs.

Cons

• Maintenance Intensity: The lifting keel system requires more oversight than a fixed-fin keel.
• Performance Trade-offs: The large keel box takes up significant interior volume and the hull shape is not optimized for light-wind racing.
• Aging Systems: Original engines and electrical panels on many models are nearing the end of their functional lifespan.
