Designed by the prolific Australian naval architect Peter Cole, the Cole 23 stands as one of the most successful and enduring examples of the versatile "trailer sailer" era. Launched primarily in the late 1970s and 1980s, the model was produced by several prominent builders, most notably Northshore Yachts and Binks Yacht Constructions. The design was conceived to provide a legitimate cruising experience for families while maintaining the portability required for inland lakes and coastal hopping. Its reputation is built upon a hull that manages to be both forgiving for novices and rewarding for seasoned sailors who appreciate the Peter Cole pedigree of balanced, seaworthy lines.

Sailing Performance & Handling

The Cole 23 is frequently lauded for its "big boat" feel despite its modest 7-meter length. Much of this is attributed to its ballast-to-displacement ratio, which typically hovers around 40%, providing a stiffness that many contemporary trailer sailers lacked. It was produced in two primary configurations: a swing-keel version for easy trailering and a fixed-keel version intended for permanent mooring and more rigorous club racing.

The boat’s sailing characteristics are defined by its masthead sloop rig. In light air, the Cole 23 is surprisingly nimble; technical data suggests a high Sail Area/Displacement ratio, which can make it feel "over-rigged" if a large genoa is carried into a freshening breeze. According to editorial reviews from Derwent Boat Sales, the vessel is light and responsive on the helm, particularly when balanced with the appropriate headsail. However, owner anecdotes from the Australian sailing community often note that the boat can become tender if the crew is slow to reef. When properly trimmed, the Cole 23 tracks exceptionally well for a boat of its size, a hallmark of Cole’s design philosophy which emphasized a clean flow of water to the rudder.

Interior Comfort & Variations

The most distinctive feature of the Cole 23’s interior is its "pop-top" companionway. This innovative design allows the center section of the cabin roof to be raised while at anchor, providing full standing headroom in the galley and saloon area—a rare luxury for a 23-foot sailboat. Below deck, the layout is functional and surprisingly spacious, typically configured with a V-berth forward, a central dinette that can convert to additional berths, and a compact galley to port.

While most Cole 23s were fitted with outboard motors on a transom bracket, a small number of "luxury" variants were built with small inboard diesel engines, such as the 6hp Lister, which significantly changed the weight distribution and cockpit utility. Sibling models from the same era include the smaller Cole 19 and the larger Cole 26, both of which share the same design language but cater to different towing capacities and crew sizes. The Cole 23 remains the "Goldilocks" of the range, offering the best balance of interior volume and manageable trailering.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Cole 23 with a specific focus on the structural integrity of its specialized components. Because these boats have been in service for decades, several common "gotchas" have emerged in technical circles:

  • Keel Pivot and Bolt: On swing-keel models, the pivot pin and the lifting mechanism (usually a winch and cable) are prone to wear and corrosion. Inspect the keel trunk for signs of "knocking" or lateral movement, which indicates a worn pivot.
  • Pop-Top Seals: The gaskets and lifting struts for the pop-top roof often perish over time. Water ingress around the cabin top is a common sign that the seals or the roof-securing latches need replacement.
  • Deck Compression: Like many GRP boats of this age, the area under the mast step can suffer from compression if the internal support post or the deck core has been compromised by moisture.
  • Window Leaks: The large acrylic windows are frequently a source of leaks. Because they are often through-bolted, thermal expansion can cause cracks around the fasteners or failure of the bedding compound.

Community & Resources

The boat enjoys a dedicated following, particularly in Australia, where it was a staple of the trailer-sailing boom. Technical support and rigging guides can often be found through the Northshore Yachts legacy community. While there is no longer a single active manufacturer-backed association, the model is a frequent subject of discussion in national trailer-sailer forums where owners share modifications for the keel lifting system and pop-top restorations.

The Verdict

The Cole 23 is a quintessentially balanced small yacht that bridges the gap between a performance day-sailer and a capable coastal cruiser. It remains an excellent entry point for those seeking a Peter Cole design without the maintenance overhead of a larger fixed-keel vessel.

Pros:

  • Excellent headroom and ventilation thanks to the signature pop-top roof.
  • Strong secondary stability and a "big boat" feel in coastal conditions.
  • Easily handled by a couple or even single-handed with lines led aft.
  • Large cockpit compared to other 23-footers of its generation.

Cons:

  • Can be tender in heavy air if the large headsail is not reefed early.
  • Swing-keel maintenance is critical and can be labor-intensive.
  • Limited storage for extended cruising when compared to modern high-volume designs.
