The Bruce Roberts Spray 38 represents a modern adaptation of perhaps the most celebrated cruising vessel in maritime history: the Spray, used by Joshua Slocum for the first solo circumnavigation of the globe. Designer Bruce Roberts-Goodson refined the original 19th-century lines to create a vessel optimized for contemporary construction methods and ocean voyaging. According to the designer's specifications at Bruce Roberts Custom Yachts, the Spray 38 is typically constructed in multi-chine or round-bilge steel, though plans also support aluminum, fiberglass (C-Flex), and wood-epoxy strip planking. With a beam of 13 feet and a displacement exceeding 29,000 lbs, the Spray 38 is a heavy-displacement cruiser designed for volume, stability, and the ultimate "go-anywhere" capability.

Sailing Performance & Handling

The Spray 38 is characterized by its exceptional directional stability and sea-kindliness. Utilizing a full-keel design and a high displacement-to-length ratio, the boat is built to track straight in heavy conditions, allowing for easier self-steering and reduced fatigue on long passages. Technical data from Fine Line Boat Plans indicates a draft of 4’ to 5’, depending on the configuration, which keeps the center of gravity low and contributes to a stiff, predictable motion in a seaway.

While the original Spray was notorious for limited windward ability, Roberts-Goodson modified the hull's entry and exit to improve performance on the breeze. However, sailors should expect a "sedate" pace; owners reporting to the designer note that in 20 knots of wind, the boat comfortably maintains 6 to 7 knots off the wind. It is a vessel that carries its momentum through chop rather than zipping over it. Handling is described as manageable for a couple, though its significant mass requires careful planning during close-quarters maneuvering in marinas.

Interior Comfort & Variations

The Spray 38’s 13-foot beam and high freeboard translate into massive interior volume that rivals many 45-foot production yachts. Because these boats are often custom-built from plans or kits, the interior configurations vary significantly. The most popular variant is the "Centennial Spray 38," which often features a "poop deck" (a raised aft section) that creates a cavernous aft cabin with full standing headroom.

Standard layouts typically include a large salon with a dedicated navigation station and a robust galley designed for use at sea. Many versions utilize a center-cockpit layout to maximize privacy between the forward and aft cabins. The design easily accommodates a pilot house or a hard dodger, which further extends the living space into a protected "deck salon" environment. Sibling models, such as the smaller Spray 33 or the larger Spray 40, follow similar logic, but the 38 is widely considered the "sweet spot" for a cruising couple requiring long-term livability without the maintenance overhead of a 40+ foot steel hull.

The Spray 38 enjoys a storied reputation in the cruising community as the "ultimate" blue-water vessel for those prioritizing safety over speed. It is featured extensively in Bruce Roberts’ own book, Spray: The Ultimate Cruising Boat, which catalogs the voyages of hundreds of Sprays that have completed circumnavigations. The design's cultural footprint is inextricably linked to Slocum’s legacy, often appearing in nautical literature and YouTube voyaging channels as the quintessential "rugged" cruiser.

Known Issues & Buyer’s Checklist

As a vessel frequently built by amateurs or small yards, the primary "gotcha" for a Spray 38 is the quality of the original construction.

  • Corrosion in Steel Hulls: In steel versions, inspection must focus on the internal bilges. A common issue involves stringers that were not "notched" to allow water to drain to the sump, leading to standing water and hidden rust behind furniture or insulation.
  • Insulation Quality: Buyers should verify the type of insulation used. Closed-cell spray foam is the gold standard for steel boats to prevent condensation-induced rust; older boats with fiberglass batts or no insulation may suffer from significant "sweating" and corrosion.
  • Amateur Wiring and Plumbing: Systems vary wildly. A professional marine survey should prioritize the electrical panel and through-hull installations, as these are often the first areas where amateur builders cut corners.
  • Rudder and Pintle Wear: Given the heavy displacement and full keel, the rudder hardware is under immense load. Check for play in the pintles and gudgeons, especially on boats that have seen significant ocean miles.

Community & Resources

The Spray 38 is supported by a robust community of builders and owners. The Bruce Roberts official site remains the primary repository for technical support and new plans. Owners often congregate in specialized groups such as the Spray Owners Association, though much of the technical knowledge is shared through general metal-boat-building forums and the designer’s own newsletters.

The Verdict

The Bruce Roberts Spray 38 is a quintessential "tank" for the high seas, trading modern agility for traditional safety and immense living space.

Pros:

  • Extreme stability and predictable motion in heavy weather.
  • Massive interior volume for its length.
  • Inherent strength of steel or wood-epoxy construction.
  • Customizable rigs (Ketch, Cutter, or Junk) to suit owner preference.

Cons:

  • Slow performance in light winds and limited windward ability.
  • Significant maintenance requirements for steel-hulled versions.
  • Variable build quality depending on the original builder.
  • Heavy displacement makes it difficult to stop and maneuver in tight spaces.
