Wylie 39 Information, Review, Specs

Sailing Performance & Handling

The Wylie 39 is defined by a displacement-to-length (D/L) ratio of approximately 132 and a sail area-to-displacement (SA/D) ratio exceeding 24, firmly placing it in the category of a light-displacement racer. With a displacement ranging between 9,500 and 11,500 pounds and a ballast ratio near 50%, the boat is remarkably stiff and stable. This high ballast-to-displacement ratio allows it to carry a significant masthead rig—which some technical reviews categorize as "over-rigged"—enabling exceptional performance in light-air conditions where heavier cruisers struggle.

Handling is characterized by a balanced helm and a high degree of maneuverability provided by its fin keel and spade rudder. Because many of these hulls were built with performance in mind, they often feature advanced materials like carbon fiber in the mast or rudder shafts to reduce weight aloft and improve tracking. The design's ability to "surf" is a hallmark of Wylie’s hull shapes, particularly on downwind legs where it can easily exceed its theoretical hull speed of 7.6 knots. Variants equipped with the Wyliecat "wishbone" rig offer a different experience, behaving like an "automatic transmission" for sailing; the unstayed carbon mast flexes to spill power in gusts, reducing the need for constant reefing.

Interior Comfort & Variations

Because the Wylie 39 was a custom-build project for Westerly Marine, interiors vary significantly across the fleet. Cruising-oriented hulls like the well-known Flashgirl feature exquisite joinery, a sculpted transom, and a focus on long-term livability, while racing versions may have sparser, utility-focused accommodations to save weight. Headroom typically averages between 5'6" and 6'3" depending on the sheerline height specified during construction.

The layout often includes a functional galley with a double sink and propane stove, though the placement of settees and berths was frequently inverted or customized. For instance, the later Wyliecat 40, which utilized a modified version of the 39 mold, moved the salon into the bow and placed quarter berths near the engine to optimize space for a larger cockpit. In many hulls, the use of white laminates and light woods reflects Tom Wylie’s preference for "open and airy" spaces that require less maintenance than traditional heavy-teak interiors.

Popular Mentions & Media

The Wylie 39 has a storied history on the West Coast racing circuit. The vessel Lightspeed is a notable veteran of the Pacific Cup and the Singlehanded Transpac, having secured a first-place finish in the 2012 Pacific Cup. Another iconic hull is Flashgirl, built for legendary sailor Warwick "Commodore" Tompkins, which showcased the design’s capability as a custom cruising yacht capable of extreme offshore voyages. The design has been regularly featured in Latitude 38, where it is frequently cited as a pinnacle of custom West Coast boatbuilding.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Wylie 39 with a focus on its composite construction and custom systems.

• Deck Core Integrity: Like many Airex-cored fiberglass boats of this era, moisture ingress around deck hardware is a primary concern. Spongy spots or high moisture meter readings near the chainplates or winches can indicate the need for expensive re-coring.
• Rigging Age: Many hulls were originally equipped with rod rigging. If this has not been replaced within the last 10–12 years, it should be considered "end-of-life" regardless of visual appearance.
• Custom Engineering: Because these are semi-custom boats, buyers must verify the engineering of the mast step and rudder. High-stress racing can lead to compression issues at the mast step, and several owners have upgraded to carbon-shaft rudders to modernize the steering system.
• Auxiliary Systems: Some racing hulls were fitted with minimal tankage (e.g., 10-gallon fuel tanks) and basic electrical systems that may require significant upgrades for cruising use.

Community & Resources

The community for the Wylie 39 is concentrated within the broader Wylie Design Group and the Wyliecat association. While not a high-volume production boat, technical support is often available through the original designer, Tom Wylie, and the builder, Westerly Marine, which continues to operate as a specialist in custom composite marine projects.

The Verdict

The Wylie 39 is a "sailor’s sailboat," offering a level of performance and build quality rarely found in mass-market production yachts. It is best suited for those who prioritize sailing sensations and speed over voluminous "apartment-style" interiors.

Pros:

• Exceptional Light-Air Performance: The high SA/D ratio ensures the boat moves when others are motoring.
• High-End Construction: Built by Westerly Marine, known for pioneering work in carbon and composites.
• Timeless Lines: The low freeboard and sleek profile remain aesthetically modern.
• Versatile Platform: Identical hull molds have successfully served as both hardcore racers and bluewater cruisers.

Cons:

• Varying Headroom: Some hulls may feel cramped for taller sailors depending on the custom sheerline.
• Maintenance Intensive: High-performance rigs and custom systems require more specialized care than a standard coastal cruiser.
• Limited Tankage: Racing variants often lack the fuel and water capacity needed for extended cruising without modification.
