The Nomad 20, a design born from the collaboration of Howard Siddons and the legendary Harry Sindle, represents a pivotal moment in the transition of American sailing from traditional wood to performance fiberglass. Introduced in the mid-1960s by the New Jersey-based Siddons & Sindle, the Nomad 20 was engineered as a versatile "family-sized" daysailer with overnighting capabilities. It followed the successful Barnegat 17 and preceded the more racing-oriented Buccaneer 18. The design philosophy behind the Nomad 20 was rooted in Sindle’s championship pedigree; as a National Sailing Hall of Fame inductee, Harry Sindle prioritized hulls that remained responsive even when loaded with family gear. At approximately 20 feet, 9 inches in length, the Nomad 20 was significantly larger than its contemporaries, offering a substantial 7-foot, 6-inch beam that provided the stability required for coastal exploration and "pocket cruising."

Sailing Performance & Handling

The Nomad 20 is characterized by its retractable centerboard design, which allows for a minimum draft of approximately one foot, making it an exceptional choice for the shallow bays of the Jersey Shore and the Chesapeake. With the board down, the draft extends to nearly five feet, providing the lateral resistance necessary for efficient upwind work. Performance-wise, the boat reflects Sindle's experience in the Flying Dutchman class; while it is heavier than a pure racing dinghy at roughly 1,500 pounds, it maintains a high sail-area-to-displacement ratio that ensures it remains lively in light air.

Handling is described by owners as forgiving yet technical. The boat tracks well due to its long waterline, but like many Sindle designs, it rewards active trimming. The large cockpit—a hallmark of the Siddons & Sindle era—allows the crew to move weight forward or aft to trim the boat effectively for different points of sail. Unlike its more aggressive sibling, the Buccaneer, the Nomad 20 has more substantial "shoulder" in the hull, which provides a predictable hardening of the helm as the boat heels, signaling the limit to novice sailors before a knockdown occurs.

Interior Comfort & Variations

Unlike the open-deck Barnegat 17, the Nomad 20 features a dedicated cuddy cabin that transformed it from a mere daysailer into a "micro-cruiser." The interior is utilitarian, focusing on maximizing the limited volume of a 20-foot hull. It typically features two full-length V-berths with storage underneath, though some later custom configurations included small shelving units for navigation or basic cooking gear.

The cabin's primary function is as a dry refuge and storage area for sails and camping equipment, but the headroom—though restricted—is sufficient for sitting. The materials used reflect the early fiberglass era, often featuring molded-in non-skid surfaces and teak or mahogany trim that added a touch of traditional craftsmanship to the modern hull. While no significant cabin variants were officially marketed, the "Nomad" name was occasionally associated with different custom cockpit layouts, though the standard 20-foot hull remained the constant platform for the model's production run.

Known Issues & Buyer’s Checklist

Prospective buyers of a vintage Siddons & Sindle Nomad 20 should prioritize a thorough inspection of the fiberglass laminate and structural components, as these vessels are now decades old.

  1. Centerboard Trunk and Pivot: The most critical mechanical area is the centerboard trunk. Inspect for stress cracks where the trunk meets the hull. The pivot bolt can wear over time, leading to "clanking" or, in severe cases, water ingress.
  2. Deck Delamination: Like many boats of this era, the Nomad 20 utilized a cored deck in certain sections for stiffness. Use a phenolic hammer to tap for "dead" sounds that indicate moisture intrusion and core rot, particularly around the chainplates and the mast step.
  3. Mast Step Compression: Check the area directly beneath the mast. Over-tensioning the rig over decades can lead to a slight depression in the deck or cabin top if the internal support post (if equipped) or the fiberglass structure has fatigued.
  4. Rudder Assembly: The original kick-up rudders are prone to wear at the pintles and gudgeons. Ensure the kick-up mechanism functions smoothly and that the blade has not suffered from water absorption and subsequent "wicking" or blistering.

Community & Resources

While there is no longer a formal factory association for Siddons & Sindle, the Nomad 20 enjoys a legacy within the broader community of Harry Sindle designs. Information is often shared among enthusiasts of his other works, such as the Buccaneer and Mutineer. The National Sailing Hall of Fame remains the primary historical repository for Sindle’s design contributions, while regional sailing clubs in New Jersey and Virginia often maintain archival knowledge of these specific hulls due to their localized popularity during the 1960s and 70s.

The Verdict

The Nomad 20 is a classic example of the "everyman’s cruiser" from a golden era of American boat building. It balances the DNA of a racing dinghy with the practical requirements of a family weekend boat.

Pros:

  • Exceptional Versatility: The centerboard design makes it perfect for "gunkholing" and beaching.
  • Proven Pedigree: Designed by a Hall of Fame sailor, ensuring a level of performance rarely found in modern small cruisers.
  • Large Cockpit: Offers more seating and working space than many modern 22-footers.

Cons:

  • Aging Hardware: Original fittings may be difficult to source and likely require upgrading to modern blocks and lines.
  • Niche Support: Lacks the massive one-design class support found with the Buccaneer 18.
  • Weight: At 1,500 lbs, it requires a substantial trailer and is more difficult to ramp-launch than a lighter 17-foot daysailer.
