Westerly Merlin 28 Information, Review, Specs

Sailing Performance & Handling

The Merlin 28 was designed to be a "step up" in performance compared to predecessors like the Centaur or the Griffon. By utilizing a more modern, slippery hull shape and a higher aspect rig, Dubois ensured the boat was capable of respectable speeds, even in lighter airs. According to technical assessments found via the Westerly Owners Association, the Merlin was offered with both fin and twin (bilge) keel configurations. The fin keel version is noted for its ability to point significantly higher than previous Westerly models, while the bilge keel version—highly popular in the UK's drying harbors—maintains surprising stability and tracking for a shallow-draft vessel.

In terms of handling, the Merlin 28 is described as well-balanced with a relatively light helm. The displacement-to-length ratio suggests a moderate-displacement cruiser that carries its momentum well through a chop, a characteristic often praised in editorial retrospectives by Yachting Monthly. Because the mast is deck-stepped and the rig is a simple fractional setup, it is easily managed by a couple, though the large genoa requires a bit of winching power in a freshening breeze.

Interior Comfort & Variations

The interior of the Merlin 28 was revolutionary for a 28-foot boat in the mid-1980s, primarily due to the inclusion of a dedicated aft cabin. This layout allowed for a level of privacy rarely seen in vessels under 30 feet at the time. The standard configuration features a linear galley to port, a functional chart table to starboard, and a central saloon with a folding table that can accommodate five to six adults. The use of mahogany joinery provides a warm, traditional feel, though the abundance of wood can make the cabin feel slightly darker compared to modern, window-heavy designs.

Throughout its production, the model saw minor variations, but the most notable sibling is the Merlin 29. Built on the same hull, the Merlin 29 featured an integrated "sugar scoop" bathing platform on the transom, which slightly increased the waterline length and provided easier access from a dinghy. Inside, the 29 occasionally offered more modern upholstery and revised locker layouts, but the core structural footprint remained identical to the 28. Headroom is a standout feature, with roughly 6 feet available in the main saloon, making it a viable long-term cruiser for taller sailors.

Known Issues & Buyer’s Checklist

Prospective buyers of a Westerly Merlin 28 should prioritize a few specific technical areas that are common across the Westerly range of this era:

• Headlining Sag: Perhaps the most famous "Westerly Gremlin" is the failure of the foam backing on the interior vinyl headlining. Over decades, this foam disintegrates, causing the vinyl to sag or fall. Replacing this is a labor-intensive DIY job or a moderately expensive professional fix.
• Osmosis Prevention: While Westerly hulls were robustly built, boats from the early-to-mid 80s are at an age where osmotic blistering can occur if the gelcoat has not been shielded by an epoxy barrier coat. A moisture meter reading during survey is essential.
• Engine Maintenance: Most Merlins were originally fitted with the Volvo Penta 2002 series engine. While reliable, these engines are now reaching the end of their expected lifespans. Check for "smoking" on cold starts and ensure the heat exchanger has been regularly descaled.
• Keel Bolts and Reinforcement: On bilge keel models, it is important to inspect the internal "top hats" or strengthening ribs where the keels attach to the hull. While the Merlin did not suffer from the "keel wobble" issues of some earlier models, any signs of crazing or movement in the bilge should be professionally evaluated.

Community & Resources

The primary hub for technical support and historical data is the Westerly Owners Association, which is one of the largest and most active owner groups in the world. They maintain a comprehensive "Knowledge Base" that includes original brochures, wiring diagrams, and specific maintenance guides for the Merlin 28 and its successor, the Merlin 29.

The Verdict

The Westerly Merlin 28 remains one of the most practical and seaworthy small cruisers on the second-hand market. It offers a rare combination of Dubois-designed performance and a "big boat" interior layout that includes a genuine aft cabin.

Pros:

• Excellent interior volume for a 28-foot hull, including a private aft cabin.
• Strong sailing performance, particularly in the fin-keel variant.
• High build quality and a robust, active owner community for parts and advice.
• Available in a bilge-keel version for shallow-water cruising and drying moorings.

Cons:

• Interior headlining is prone to sagging and often requires replacement.
• Original Volvo Penta engines may be nearing the need for a costly repower.
• The traditional dark wood interior can feel somewhat cramped by modern light-filled standards.
