The Reynolds 21 is a landmark design in the evolution of the performance cruising catamaran, representing a departure from the traditional beach cats of the 1980s toward a more versatile, "oversquare" platform. Designed by Randy Reynolds and introduced in the mid1980s, this 21foot multihull was engineered to provide the stability and speed of a much larger vessel while maintaining the agility of a day racer. Its most defining characteristic is its extraordinary 12foot beam, which provides a righting moment far superior to contemporary designs like the Hobie 18 or Prindle 19. Built primarily in Southern California, the Reynolds 21 catered to a niche of sailors who demanded highspeed coastal capability and enough deck space to accommodate small groups without the cramped confines of a narrowbeamed racing cat.

Sailing Performance & Handling

The sailing dynamics of the Reynolds 21 are defined by its high-aspect-ratio hulls and its massive beam-to-length ratio. Unlike standard beach catamarans that often feel "flighty" in a breeze, the Reynolds 21 remains remarkably level, translating wind energy directly into forward motion rather than excessive heeling. The boat typically features a rotating mast and a high-performance sail plan, often including a large reacher or asymmetrical spinnaker for off-wind legs.

According to technical insights from Reynolds Sailing, the design philosophy focused on reducing hull drag while maximizing the power-to-weight ratio. Owners frequently report that the boat tracks exceptionally well thanks to its deep daggerboards, which allow it to point higher than many of its peers. The kick-up rudders and boards are essential for coastal exploration, enabling sailors to navigate shallow waters or beach the craft with ease. Handling is described as sensitive but forgiving; the wide stance makes it difficult to "pitchpole," a common fear on narrower 20-foot multihulls. In a stiff breeze, the boat is known to reach speeds in the mid-20-knot range, yet it remains stable enough to be handled by a crew of two.

The Reynolds 21 earned a rugged reputation through its participation in grueling distance races, most notably the Worrell 1000 and various coastal sprints along the California and Florida coastlines. It became a favorite for "raid" style sailing long before the term was popularized, serving as the platform for several documented long-distance coastal expeditions. Its design influence is still visible in the more modern Reynolds 33, a larger sibling that carried the same high-stability, high-performance DNA into the 30-foot class.

Known Issues & Buyer’s Checklist

When inspecting a Reynolds 21 on the used market, the primary focus should be on the structural integrity of the crossbeams and the hull-to-deck joints. Given the age of these vessels, several specific areas require scrutiny:

  • Telescoping Beam Hardware: Because the 12-foot beam exceeds standard trailering widths, many Reynolds 21s were equipped with a telescoping or assembly system for transport. Inspect the stainless steel bolts and aluminum sleeves for galvanic corrosion or "freezing," which can make the boat impossible to disassemble without major surgery.
  • Hull Delamination: Early models utilized a composite sandwich construction. Check for soft spots on the decks and along the hull sides, particularly near the shroud chainplates where the highest loads are concentrated.
  • Daggerboard Trunks: High-speed groundings can crack the internal trunks. Look for signs of weeping or structural stress fractures around the trunk openings.
  • Mast Step and Rotation Bearing: The rotating mast puts significant pressure on the step. Ensure the bearing surface is smooth and the mast base shows no signs of hairline fracturing.
  • Trampoline Condition: Replacing the large-acreage trampoline on a Reynolds 21 can be expensive. Check the UV degradation of the stitching and the integrity of the hiking straps.

Community & Resources

While there is no longer a formal factory-backed class association, the Reynolds 21 remains a "cult classic" within the multihull community. Technical support is often found through the designer himself, Randy Reynolds, who remains active in the sailing industry. Enthusiasts typically congregate on broader multihull forums like TheBeachcats.com or CruisersForum, where decades of rigging modifications and repair logs are archived by long-term owners.

The Verdict

The Reynolds 21 is an uncompromising speed machine that offers a level of stability and deck space rarely found in a trailerable 21-foot package. It is best suited for experienced sailors who prioritize raw performance and coastal versatility over creature comforts.

Pros:

  • Exceptional Stability: The 12-foot beam provides a massive safety margin in high winds.
  • High Speed: Capable of outperforming much larger monohulls and most standard beach cats.
  • Shallow Draft: Kick-up rudders and boards make it ideal for "camping" and beaching.

Cons:

  • Trailering Logistics: The wide beam requires a specialized trailer or disassembly, making it less "ramp-friendly" than narrower cats.
  • Age: Most hulls are nearing 40 years old, requiring diligent maintenance of composite structures.
  • Complexity: The rotating mast and high-tension rigging require more setup time and technical knowledge than a simple daysailer.
