Design Brief & Intent
The Hughes 38-3 was designed for sailors prioritizing blue-water capability and heavy-weather safety over dockside living space. Standing in stark contrast to the modern, wide-beam "condo-marans" and beamy production cruisers of the late 1970s and 1980s, the S&S design features a narrow beam of 10.17 feet and elegant, sweeping overhangs. This design philosophy prioritizes a low-drag, easily driven hull form that excels in upwind work and handles a seaway with minimal fuss.
By the time the 38-3 went into production, the deck mold was completely redesigned. Hughes replaced the stepped coachroof of the earlier Marks with a continuous, low-profile, rounded coachroof. This change not only modernized the aesthetic but also allowed the manufacturer to push the cabin trunk further aft, increasing interior headroom and usable living space.
Inside, the boat showcases the traditional, offshore-focused carpentry of the Huron Park factory. Unlike earlier iterations that relied heavily on bare fiberglass liners, the 38-3 incorporates warm teak joinery, structural bulkheads, and a practical offshore layout. The salon utilizes a deep settee and pilot berth configuration, providing excellent, secure sea berths for off-watch crew in rough weather. While the narrow beam makes the cabin feel intimate compared to contemporary 38-footers, the interior fit-out feels robust, purposeful, and reassuringly secure.
Evolution & Configurations
The S&S hull #1903 remained the foundation for all iterations of this design, but the 38-3 introduced major structural and hardware reconfigurations. The most obvious changes are on deck: the cockpit was shortened to accommodate the longer coachroof, and the mainsheet traveler was relocated from the cockpit to the coachroof, shifting the boat to a mid-boom sheeting arrangement. This layout opened up the cockpit for easier movement while underway and kept the high-load mainsheet clear of the helmsman.
Below deck, the layout was updated to include a proper marine head with a integrated shower and dedicated hot water system—a major luxury upgrade compared to the spartan, race-oriented Mark I.
In terms of auxiliary power, early Hughes 38s were dominated by the gasoline-powered Universal Atomic 4. While some early 38-3 models still slipped out of the factory with the Atomic 4, the majority of this run transitioned to diesel power, typically utilizing small, reliable three-cylinder engines from Universal or Westerbeke.
Sailing Performance & Handling
The sailing performance of the Hughes 38-3 is defined by its conservative, heavy-displacement ratios. With a displacement of 14,500 pounds and a displacement-to-length (D/L) ratio of 328.87, this is a heavy, momentum-driven cruiser. It does not accelerate like a light-displacement modern yacht, but once moving, its tracking and motion are sublime.
With a ballast-to-displacement ratio of 44.14%—backed by a 6,400-pound keel—the 38-3 is incredibly stiff. It stands up to its canvas far longer than flatter, wider boats, allowing the crew to maintain a full mainsail well into the upper teens. The motion in a seaway is exceptionally comfortable, as indicated by its comfort ratio of 33.71. It avoids the fatiguing, snappy motion of beamy hulls, instead slicing cleanly through waves with a soft, predictable pitching motion.
A capsize screening ratio of 1.67 places the boat firmly in the category of safe, blue-water passagemakers. At the helm, the skeg-hung rudder provides a balanced, positive feel. The boat is legendary for its upwind pointing ability; the fine bow entry and deep fin keel allow the 38-3 to claw its way to windward in conditions that would force lesser boats to turn on their engines.
The only trade-off is light-air performance. A moderate sail area-to-displacement (SA/D) ratio of 15.74 means the boat can feel underpowered in winds under eight knots. To keep her moving in light air, owners must rely on large overlapping headsails (such as a 150% genoa) or asymmetric spinnakers.
Known Issues & Triage
While the hull layup of the Hughes 38-3 is thick, robust single-skin fiberglass, the deck and hardware require careful inspection due to aging and specific manufacturing methods of the era.
- Deck Core Saturation: Like many builders of the period, Hughes utilized a balsa-wood core to stiffen the deck laminate. Over the decades, water ingress around poorly bedded stanchions, handrails, the mast step, and the coachroof traveler track is common. Unattended leaks cause the balsa core to rot, leading to delamination and spongy decks. Triage requires sounding the deck with a phenolic hammer to identify dead spots, drilling test holes, and injecting epoxy or recoring affected areas with closed-cell foam.
- Chainplate Web Decay: The chainplates on the S&S 38 hull are subjected to massive loads due to the boat's high ballast ratio. Water migrating down through the deck chainplate slots frequently rots the plywood reinforcement webs and bulkheads below deck. A buyer's checklist must include a close visual inspection of the fiberglass knees and bulkheads where the chainplates are through-bolted, looking for weeping rust, crushing, or soft wood.
- The "Hughes Smile": This refers to a hairline cosmetic crack that often develops at the leading edge of the keel-to-hull joint. While usually just a failure in the fairing compound due to normal flexing, any significant rust bleeding or widening of the gap warrants dropping the keel bolts for inspection or torque-testing the nuts to ensure structural integrity.
- Rudder Bearings and Post: The spade/skeg rudder assembly should be inspected for play. Water can migrate into the rudder blade itself, freezing in cold climates and delaminating the skin from the internal skeleton.
Modernization & Upgrades
For owners committed to keeping these classics on the water, several modernization paths are common.
Repowering is the most significant investment. Many surviving 38-3s have already been converted from their original gasoline engines or early raw-water-cooled diesels to modern, fresh-water-cooled diesels like the Yanmar 3GM30F or Universal M35B. Because of the narrow engine compartment and the hull's deep V-shape, careful measurements are required when selecting a replacement engine to ensure proper shaft alignment.
Furthermore, the transition to lithium-iron-phosphate (LiFePO4) house battery banks is highly viable on this model. The deep, narrow bilge and lockers provide dry, centered spaces for battery installations, allowing owners to run modern marine refrigeration, water heaters, and navigation electronics without carrying heavy lead-acid battery banks. Some owners have even explored complete electric propulsion conversions, utilizing high-torque electric motors coupled with large lithium banks, which fits the boat's profile as an easily driven hull that is primarily sailed rather than motored.
The Verdict
The Hughes 38-3 is a highly capable, S&S-designed blue-water cruiser that trades modern interior volume for exceptional sea-kindliness, offshore safety, and upwind speed. It is a rewarding "sailor's boat" that can safely cross oceans, provided the owner is prepared to address the common maintenance realities of a vintage fiberglass yacht.
