Hylas 47 Information, Review, Specs

Sailing Performance & Handling

The Hylas 47 is celebrated for a level of sailing performance that was uncommon for its era’s center-cockpit cruisers. With a Displacement/Length ratio of approximately 289 and a Sail Area/Displacement ratio of 15.77, it sits firmly in the category of a moderate-displacement offshore voyager. The Sparkman & Stephens design features a long fin keel and a large, skeg-hung rudder, which provides a balanced feel on the helm and excellent tracking. Unlike later Hylas models designed by German Frers, the 47 (and its sibling, the 49) features an encapsulated lead ballast rather than a bolt-on keel, a feature noted by Cruising World as contributing to its structural integrity and "easy motion" in a seaway.

Owners and testers often highlight the boat's ability to maintain high average speeds, with many logging 200-nautical-mile days during transoceanic passages. The tall cutter rig provides versatility, allowing sailors to depower the boat easily in heavy weather while maintaining a powerful sail plan for light-air coastal cruising. Its PHRF rating of roughly 110 makes it competitive in point-to-point cruiser racing, though its primary strength remains its stiffness and "stiff" righting moment, making it a safe choice for families crossing oceans.

Interior Comfort & Variations

The interior of the Hylas 47 was revolutionary for the early 1980s, offering a three-stateroom, two-head layout that maximized privacy and social space. The most distinctive feature is the dual-passageway design leading to the master stateroom aft; the port side houses a long, sea-going galley, while the starboard side contains the navigation station and access to the aft head. This layout ensures that the cook and the navigator do not interfere with each other while underway.

The joinery is predominantly hand-finished teak, a hallmark of Queen Long Marine’s craftsmanship. While the layout is consistent across most hulls, David Walters Yachts notes that earlier Stevens 47 versions often featured split berths in the aft cabin for charter use, whereas the Hylas 47 versions almost exclusively utilized a centerline queen berth. One frequent critique of the 47 is its relatively low headroom in the passageways and master cabin—a limitation that was eventually addressed in the Hylas 49 sibling, which added two inches of freeboard and a taller deck house.

Popular Mentions & Media

The Hylas 47 gained significant "cult" status following its inclusion in John Kretschmer’s "Used Boat Notebook," where it was lauded for its exceptional build quality and offshore prowess. This editorial endorsement sparked a surge in demand on the brokerage market that has persisted for decades. The model is also a frequent subject in technical discussions regarding the evolution of Taiwanese "Plastic Classics," often cited as the gold standard for what a 40-year-old fiberglass hull should look like when properly maintained.

Known Issues & Buyer’s Checklist

While the Hylas 47 is exceptionally well-built, prospective buyers should focus on several aging-yacht concerns common to this vintage:

• Teak Deck Condition: Many original 47s came with thick teak decks screwed into a balsa-cored laminate. Over time, these screws can allow moisture to enter the core, leading to delamination.
• Stainless Steel Tanks: The boat was equipped with large stainless steel fuel and water tanks. If these tanks have reached the end of their life cycle, replacement is a major undertaking that often requires cutting the cabin sole or removing furniture.
• Leaky Portlights: Original opening ports are known to develop leaks, which can damage the teak veneers in the passageways.
• Chainplate Inspection: As with any blue-water cruiser over 30 years old, the stainless steel chainplates (which are robust but partially hidden) should be inspected for crevice corrosion.
• Original Plumbing: The Groco Series K toilets and original gate valves often require replacement to meet modern standards of reliability and safety.

Community & Resources

Owners are supported by the Hylas Yacht Club, an official organization that provides technical support and organizes rendezvous. Additionally, the Hylas Yacht Owners Association maintains a technical forum where decades of maintenance data regarding the 47 and its evolution into the 49 are archived for the community.

The Verdict

The Hylas 47 remains a premier choice for sailors seeking a proven Sparkman & Stephens design with the "sea-kindly" characteristics required for long-range cruising.

Pros:

• Exceptional offshore tracking and motion due to the S&S hull form.
• Encapsulated ballast provides peace of mind regarding keel attachment.
• Three-cabin layout is ideal for families or hosting guests.
• High resale value and enduring reputation for quality.

Cons:

• Lower headroom compared to the later Hylas 49 model.
• Aging teak decks and stainless steel tanks represent significant potential maintenance costs.
• The smallish center cockpit can feel crowded with more than four adults.
