Sailing Performance & Handling
The Vulcan 34 is a heavy-displacement vessel, tipping the scales at over 15,500 lbs. With a ballast-to-displacement ratio approaching 44%, it is exceptionally stiff and stable. While it lacks the light-air finesse of its pure-sailing siblings like the Fulmar, it is surprisingly capable once the wind picks up. The masthead sloop rig carries roughly 600 square feet of sail, providing enough power to maintain 6 knots in a steady breeze. Its semi-balanced rudder and rod steering system provide a degree of responsiveness that is often missing in motor-sailers of this era.
The boat's true performance identity, however, is revealed when the wind dies or turns against the bow. Equipped with a 60hp Volvo or Perkins diesel—nearly double the horsepower of contemporary 34-footers—it cruises effortlessly at 7 knots under power. The hull was specifically engineered to be efficient under both sail and machinery, avoiding the "hobby-horsing" common in older motor-sailer designs. Owners often note that the boat tracks exceptionally well in a seaway, thanks to its substantial weight and the option of either a deep fin keel (4’ 9” draft) or the classic Westerly twin bilge keels (4’ 3” draft) for drying out in tidal harbors.
Interior Comfort & Variations
The interior of the Vulcan 34 is its defining characteristic, offering a level of accommodation usually reserved for 40-foot vessels. The split-level layout centers around a light, airy deck saloon featuring panoramic windows and an internal steering position to starboard. This allows the helmsman to navigate using a hydraulic wheel while remaining sheltered from rain and spray—a feature highly prized by long-distance cruisers.
Below the saloon level, the layout is remarkably sophisticated. To port, a large galley sits opposite a dedicated owner’s double cabin located amidships. This "mid-cabin" arrangement provides better stability and less motion than a traditional V-berth for sleeping at sea. Forward of this is a heads compartment with a shower and a traditional V-berth forecabin. A distinctive "passage berth" or sea-berth is often found tucked away near the chart table. The use of high-quality teak joinery and Treadmaster non-slip surfaces throughout the interior reflects the Westerly Owners Association's documentation of the model's robust build quality.
Known Issues & Buyer’s Checklist
Prospective buyers should approach the Vulcan 34 with an eye toward the specific complexities of its motor-sailer systems.
- Engine Service Life: The original Volvo MD21B engines are reliable but now quite old. Parts for the heat exchanger and specific marinizaton components can be difficult to source. A thorough mechanical survey is essential, as the engine is the heart of this boat's "motor-sailer" utility.
- Deck and Window Integrity: The large pilothouse windows are a primary selling point but also a common failure point. Inspect for signs of "crazing" in the acrylic or leaks around the seals, which can damage the teak cabinetry below.
- Treadmaster Maintenance: Westerly heavily utilized Treadmaster non-slip pads on the decks. Over four decades, these can become unbonded or worn smooth. Replacing a full deck of Treadmaster is a labor-intensive project.
- Keel Bolts and Osmosis: Like many British boats of the early 80s, the Vulcan is susceptible to hull osmosis. Additionally, because the boat is often used as a motor-sailer and kept in tidal berths, the keel-to-hull joints (especially on bilge-keel versions) should be inspected for "Westerly smile" or movement.
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. They maintain an extensive "Westerly-Wiki" that includes original brochures, wiring diagrams, and specific maintenance guides for the Vulcan’s unique dual-steering hydraulic systems.
The Verdict
The Westerly Vulcan 34 is a "mariner’s motor-sailer"—a boat that refuses to surrender the joy of sailing while providing the shelter and power of a small trawler. It is ideal for couples looking to extend their sailing season into the shoulder months or those planning passages in northern latitudes where a dry helm is a luxury beyond measure.
Pros
- Superb all-weather protection via the internal helm.
- Massive interior volume with three separate cabin areas.
- Heavy-duty construction capable of serious offshore work.
- Powerful engine provides peace of mind in heavy currents or calms.
Cons
- Lacks the agility and light-air speed of modern performance cruisers.
- Relatively small production run makes finding well-maintained examples difficult.
- Maintenance of dual steering and large windows adds complexity and cost.
