Hatfield Discovery 42 Information, Review, Specs

Sailing Performance & Handling

Under sail, the Discovery 42 is defined by its "sea-kindliness," a term often used by owners to describe its predictable motion in heavy weather. With a displacement approaching 26,000 pounds and a ballast-to-displacement ratio of roughly 38%, the vessel is exceptionally stiff and carries its momentum well through a chop. The hull features a moderate fin keel and a substantial skeg-hung rudder, a configuration that provides a superior balance between tracking stability and maneuverability compared to the full-keel cruisers of its era.

The sail plan, often configured as a high-aspect sloop or sometimes a ketch, allows for versatility in sail shortening. While the boat is not a "light-air flyer" due to its wetted surface area and weight, it excels when the wind exceeds 12 to 15 knots. In the stiff breezes of the Salish Sea, the Discovery 42 is known for its ability to hold a course with minimal helm pressure. Steering is typically mechanical via a pedestal-mounted wheel, providing enough feedback to keep the helmsman engaged without the fatigue common in less balanced designs.

Interior Comfort & Variations

The interior of the Discovery 42 was largely dictated by its primary role as a long-distance cruiser. Most hulls were finished as center-cockpit configurations, which allowed for a magnificent, full-beam aft master stateroom—a luxury rarely found in 40-footers of the late 70s. The woodwork is characteristic of British Columbia’s boatbuilding heritage, often featuring extensive use of solid teak or mahogany and high-quality joinery that has stood the test of time.

The layout typically includes a large U-shaped galley to starboard, positioned near the companionway for optimal ventilation and safety while cooking at sea. The main saloon utilizes the boat’s 13-foot beam to provide ample seating and a dedicated navigation station. Ventilation is a highlight, with numerous opening ports and hatches designed for tropical cruising. In terms of siblings, the Discovery 37 was built on a similar design philosophy, though the 42 offers significantly more volume in the ends of the boat, making it much better suited for live-aboard couples.

Known Issues & Buyer’s Checklist

Prospective buyers of a Hatfield Discovery 42 should focus their surveys on the typical vulnerabilities of high-quality fiberglass yachts from the late 20th century. While the hulls are generally solid, several key areas require scrutiny:

• Deck Core Integrity: Like many boats of this era, the decks were often cored with balsa or plywood. Inspectors should check for soft spots or elevated moisture levels around stanchion bases, windlasses, and chainplates, where hardware bedding may have failed.
• Fuel and Water Tanks: The original tanks were often made of black iron or aluminum and may be reaching the end of their service life. Given the boat's internal cabinetry, replacing these can be a labor-intensive project.
• Chainplate Inspection: The chainplates are robust, but their mounting points and the bolts themselves should be inspected for crevice corrosion, especially if the boat has spent time in warm, tropical waters.
• Osmotic Blistering: While Hatfield designs used thick laminates, some hulls from the Discovery Marine yard have been noted to develop minor osmotic blistering. A bottom survey after a period of drying is recommended.

Community & Resources

While there is no longer a dedicated manufacturer website, the legacy of Peter Hatfield's designs is preserved through regional sailing organizations in Western Canada. Owners often frequent the BC Sailing associations and local yacht clubs where "Hatfield" is a respected name. Technical information is frequently shared through regional cruising forums where the boat’s PNW heritage is celebrated.

The Verdict

The Hatfield Discovery 42 is a connoisseur’s cruiser, offering a level of build quality and sea-keeping that far exceeds modern entry-level production boats. It is an ideal choice for a couple looking to transit the Inside Passage or cross the Pacific in comfort and safety.
