Name: McGruer Clipper 23
Brand: McGruer

Sailing Performance & Handling

Under sail, the Clipper 23 is characterized by its predictable and forgiving nature. With a displacement-to-length ratio that leans toward the heavier side of the "moderate" category, the boat tracks well and resists being tossed about by afternoon chop. The Alex McGruer design incorporates a relatively high ballast ratio—often exceeding 40%—which translates to a stiff boat that carries its canvas well into a freshening breeze. This stiffness is a hallmark of McGruer’s designs, which were influenced by the heavy-weather requirements of the North Sea.

While the boat is not a light-air flyer, its masthead rig provides a generous headsail area that helps generate momentum in moderate conditions. Its tracking is aided by a fixed fin keel and a spade rudder, though some owners report that the rudder can feel heavy if the boat is over-canvased. For optimal performance, the Clipper 23 requires early reefing; once the rail approaches the water, the boat’s speed plateaus, and it becomes more efficient to flatten the sail plan. It is a "sea-kindly" vessel for its size, offering a sense of security that is often missing in more modern, flat-bottomed daysailers.

Interior Comfort & Variations

For a 23-foot vessel designed in the 1970s, the Clipper 23 offers a remarkably functional "pocket cruiser" interior. The layout typically features a standard four-berth configuration: a forward V-berth for two and two longitudinal settees in the main salon. Because the beam is carried relatively well aft, the cabin feels less claustrophobic than some of its 20-foot peers, though headroom remains a limitation for taller sailors, typically topping out around 5' 6".

The interior aesthetic is heavily influenced by the era, featuring extensive use of teak trim and molded fiberglass liners that simplify maintenance. Variations were primarily limited to the galley arrangements; most units featured a simple pull-out stove and a small sink located near the companionway for ventilation. The Clipper 23 shares much of its structural DNA with its larger sibling, the Challenger 24 (also known as the Challenger 7.4). While the 24-footer offers a dedicated enclosed head, the Clipper 23 usually utilizes a "porta-potti" arrangement tucked under the V-berth, a common compromise for vessels in the sub-25-foot class.

Known Issues & Buyer’s Checklist

Prospective buyers of a Clipper 23 should focus their inspection on the structural integrity of the aging fiberglass and the specific hardware choices made by Challenger Yachts Ltd. during the 1970s.

Deck Delamination: Like many Canadian-built boats of this era, the Clipper 23 uses a balsa-cored deck. Over decades, hardware such as stanchion bases and cleat mounts can leak, leading to core rot. Soft spots on the foredeck or near the chainplates are a primary "gotcha" for this model.
Keel-to-Hull Joint: The transition where the cast iron or lead keel meets the fiberglass stub should be inspected for the "smile"—a hairline crack that suggests the keel bolts may need tightening or that the sealant has failed.
Original Wiring: The electrical systems in these boats were basic. Many still have original glass-fuse panels and non-tinned copper wiring, which are prone to corrosion and should be upgraded for safety.
Window Leaks: The large side ports are known to leak over time as the original bedding compound dries out. Re-bedding these is a common and necessary DIY project for new owners to protect the interior woodwork.

Community & Resources

While there is no longer a formal factory presence for Challenger Yachts Ltd., the community of owners remains active in the Great Lakes region. The most reliable technical data and historical context for the Clipper 23 are often found through the Canadian Power and Sail Squadrons or through regional vintage yacht clubs that celebrate "McGruer" designs. Because Alex McGruer was a prominent figure in UK yacht design, some technical cross-over information regarding his scantlings and rigging philosophies can be found through Scottish maritime archives.

The Verdict

The McGruer Clipper 23 is a sturdy, "big-feeling" small boat that offers an affordable entry point into cruising for those who value traditional aesthetics and heavy-weather capability over racing performance.
