The Westerly Merlin 29, introduced in 1984, represents a pivotal shift for the renowned British builder as it transitioned from the rugged, traditional designs of Jack Laurent Giles to the more contemporary, performance-oriented lines of Ed Dubois. Designed to modernize the Westerly fleet, the Merlin was intended to offer a faster, more agile alternative to the aging Konsort and Centaur models. It succeeded by blending a sophisticated hull form with a surprisingly spacious interior for a vessel under 30 feet. While the company's American namesake, Westerly Marine Inc. of California, focused on custom carbon-fiber racing machines, the British-built Merlin 29 became a cornerstone of European family coastal cruising, eventually evolving into the Merlin 28 and later the Regatta 290.

Sailing Performance & Handling

The influence of naval architect Ed Dubois is immediately apparent in the Merlin 29’s handling characteristics. Unlike earlier Westerlys that prioritized ultimate stability over speed, the Merlin features a more refined entry and a flatter run aft, allowing it to perform well even in light airs. According to editorial analysis from Yachting Monthly, the boat is notably well-balanced, though it requires early reefing as the breeze nears 15–18 knots due to its relatively high power-to-weight ratio for a cruiser of its era.

The Merlin was offered in both fin keel and twin (bilge) keel configurations. While the fin keel provides superior pointing ability and reduced leeway, the twin keel version remains highly sought after for its ability to dry out in tidal harbors—a hallmark of the Westerly brand. The fractional rig, common on later models, allows for better mainsail control and easier headsail handling compared to the heavy masthead rigs of the 1970s. Owners often report that the boat tracks exceptionally well for its length, making it a "forgiving" vessel for short-handed crews.

Interior Comfort & Variations

For a 29-foot yacht, the Merlin’s interior was revolutionary at the time of its launch. By utilizing the full beam and employing a clever aft-cabin layout, Dubois managed to fit six berths into the hull without making the saloon feel cramped. The inclusion of a dedicated, separate aft cabin—uncommon in sub-30-footers in the mid-1980s—provided a level of privacy that appealed to families.

The cabin is finished with the classic Westerly teak joinery, though the "Merlin 29" update (which was largely a rebranding of the Merlin 28 with minor aesthetic tweaks) introduced lighter wood tones and more modern fabrics in later years. The galley is functional, typically featuring a two-burner stove and oven, while the heads are located aft on the starboard side. A notable sibling to the Merlin is the Westerly Regatta 290, which used the same hull mold but featured a revised deck and a more "Euro-style" interior during the early 1990s. This hull was also the precursor to the Westerly Tempest 31, which expanded on the aft-cabin concept with even greater volume.

Known Issues & Buyer’s Checklist

Prospective buyers of a Westerly Merlin 29 should be aware of several "signature" issues common to the brand during this production period. While the hulls are generally robust, they are not immune to the passage of time or specific manufacturing quirks.

  • Headlining "Droop": Like nearly all Westerlys of the 1980s, the Merlin is notorious for its sagging headlining. The foam backing of the vinyl panels eventually disintegrates, causing the material to hang. Many examples on the market have already been repaired with wooden laths or professional replacements.
  • Keel Joint Stress: On bilge keel versions, it is critical to inspect the "keel stubs" or the area where the keels meet the hull. Over years of drying out on hard ground, the flexing can lead to stress crazing in the gelcoat or, in extreme cases, structural weeping.
  • Engine Maintenance: Most Merlins were originally fitted with the Volvo Penta 2002 series engine. While reliable, these units are now decades old and can suffer from cooling system blockages or splined shaft wear between the engine and the gearbox.
  • Osmosis: While Westerly used high-quality resins, any GRP boat of this vintage should be checked for osmotic blistering, particularly if it has spent its entire life in the water without an epoxy barrier coat.

Community & Resources

The Merlin 29 is supported by one of the most active owner groups in the maritime world. The Westerly Owners Association serves as a vital repository for technical manuals, spare parts sourcing, and historical data. Their technical "wiki" is the gold standard for owners looking to tackle specific repairs like the aforementioned headlining or keel bolt maintenance.

The Verdict

The Westerly Merlin 29 is a quintessential "pocket cruiser" that manages to feel larger than its dimensions suggest. It represents a successful marriage of Ed Dubois’s racing pedigree and Westerly’s reputation for solid, dependable construction.

Pros:

  • Innovative interior with a genuine aft cabin.
  • Well-mannered sailing performance, especially in light to moderate winds.
  • Strong resale value and an exceptionally supportive owner association.
  • Twin keel option allows for versatile tidal cruising.

Cons:

  • Aesthetic issues like sagging headlining are almost guaranteed unless previously fixed.
  • Original Volvo engines may be reaching the end of their service life.
  • Can become "tender" (heel quickly) if not reefed early in heavy weather.
