The Clipper Marine 1/4 Ton represents a unique intersection of the IOR (International Offshore Rule) racing era and the 1970s boom in trailerable family cruisers. Designed by the legendary William Crealock and produced by Clipper Marine in Santa Ana, California, this 23.58-foot vessel was a Departure from the company’s more utilitarian cruising models. While most of the Clipper Marine fleet prioritized interior volume and ease of trailering for weekenders, the 1/4 Ton was a deliberate attempt to capture the performance-oriented market of the mid-1970s. It utilized the fiberglass construction techniques that defined the builder, but with a hull form influenced by the "Quarter Ton" racing class that was gaining massive popularity in Europe and North America at the time.

Sailing Performance & Handling

The sailing characteristics of the Clipper Marine 1/4 Ton are defined by its IOR heritage, which typically favored a pinched stern and a relatively wide beam amidships. Unlike the standard Clipper Marine 23, which was designed primarily for stability and ease of handling for novice sailors, the 1/4 Ton variant featured a more aggressive sail plan and a hull optimized for competitive ratings. According to historical design notes from the William Crealock archives, the boat was intended to be "lively" in light to moderate air, a necessity for the Southern California racing circuit where it was born.

In practice, the boat behaves like a classic light-displacement racer-cruiser. Its high sail area-to-displacement ratio allows it to accelerate quickly in puffs, though it requires active trimming and weight placement to maintain an optimal heel angle. Because many units were equipped with a swing keel to maintain the brand’s signature trailerability, the 1/4 Ton can feel somewhat tender when compared to dedicated fixed-keel racing yachts of the same era. However, the versatility of the lifting keel allowed sailors to optimize their center of gravity for different points of sail, a feature often discussed in early 1970s promotional materials as a "best of both worlds" compromise between racing performance and gunkhole accessibility.

Interior Comfort & Variations

The interior of the Clipper Marine 1/4 Ton is intentionally Spartan, reflecting its primary mission as a racing machine. While it retains the basic "four-sleeper" layout found in many 24-footers of the era, the emphasis was on weight savings rather than luxury. The cabin provides a V-berth forward and two quarter berths extending aft under the cockpit seats. Headroom is limited—a common trait for Crealock designs of this size—prioritizing a lower profile and reduced windage for better performance on the racecourse.

The 1/4 Ton is often confused with its siblings, the Clipper Marine 23 and the slightly larger Clipper Marine 26. While they share similar fiberglass layup schedules and the trademark Crealock aesthetic, the 1/4 Ton is a distinct hull. The Clipper Marine 23 served as the high-volume cruising counterpart, while the 1/4 Ton was the "tuned" version. Buyers should note that interior finishes often vary significantly; because these boats were relatively affordable when new, many owners customized the cabinetry and soft goods, meaning no two interiors are likely to be identical today.

Known Issues & Buyer’s Checklist

Prospective owners of a Clipper Marine 1/4 Ton should prioritize a structural inspection of the keel assembly and deck core. Like many fiberglass boats from the 1970s, the Clipper Marine line utilized a plywood-cored deck that is susceptible to delamination if hardware was not properly bedded and maintained.

  1. Swing Keel Pivot and Cable: The pivot pin and lifting cable for the swing keel are the most critical mechanical components. Corrosion in the pin or fraying of the cable can lead to catastrophic failure. Inspections should look for "keel clunk," which indicates wear in the pivot hole.
  2. Mast Step Compression: The 1/4 Ton’s rig is more powerful than the standard cruising models. Inspect the area around the mast step for sagging or hairline cracks, which may indicate that the internal compression post or the deck core beneath the step has compromised structural integrity.
  3. Rudder Hardware: The "one-line" uphaul/downhaul system for the kick-up rudder was an innovation of Crealock’s but can be prone to jamming if the components are weathered or the lines are not correctly routed.
  4. Hull-to-Deck Joint: Look for signs of "weeping" or water ingress along the rub rail, as the mechanical fasteners used in the 1970s can loosen over decades of trailering and thermal expansion.

Community & Resources

While the original manufacturer is no longer in business, the legacy of William Crealock's designs ensures a dedicated following. The most prominent technical resource for owners is the Clipper Marine Owners Association, a long-standing group that maintains archives of original brochures and technical manuals. Information regarding Crealock's specific design philosophy for the Clipper line can also be found through the W.I.B. Crealock Design Portfolio via Cruising World, which highlights his commitment to seaworthiness even in smaller trailerable vessels.

The Verdict

The Clipper Marine 1/4 Ton is a fascinating relic of the 1970s racing scene, offering a pedigree that is rare for a trailerable boat of its price point. While it lacks the interior refinements of modern pocket cruisers, it offers a more engaging sailing experience for those who enjoy "tweaking" their rig and participating in local club racing.

Pros:

  • Excellent Pedigree: Designed by William Crealock, ensuring a well-balanced and aesthetically pleasing hull.
  • Versatile Transport: One of the few 1/4 Ton class boats that can be easily trailered and launched from a ramp.
  • Performance: Significantly faster and more responsive than the standard Clipper Marine 21 or 23 cruising models.

Cons:

  • Minimalist Interior: Not suited for extended cruising or families requiring modern amenities and standing headroom.
  • Age-Related Maintenance: Potential for deck delamination and swing keel wear requires a vigilant owner.
  • Tenderness: The light displacement and IOR hull shape require active management in heavy weather.
