The Calgan 23, frequently referred to in Pacific Northwest sailing circles as the Crown 23, represents a pivotal moment in Canadian boatbuilding when local manufacturers began transitioning from licensed production to proprietary design. Developed and built by Calgan Marine Ltd. in North Vancouver, British Columbia, during the 1970s, the vessel was the brainchild of company founder Al Nairne. While Nairne had established his firm’s reputation by building C. William Lapworth’s famed "Cal" designs under license, the 23 was a local evolution of the Cal 24-2 hull. By refining the lines and deck layout, Calgan Marine created a robust, fiberglass pocket cruiser specifically optimized for the light-to-moderate winds and the short, steep chop typical of the Salish Sea.

Sailing Performance & Handling

The Calgan 23 is characterized by a high degree of "stiffness" for its size, a trait inherited from its Cal Yachts lineage. Utilizing a fixed fin keel and a high-aspect spade rudder, the boat tracks with remarkable precision compared to many of its contemporary swing-keel competitors. Because it was designed in an era where club racing was the primary driver of sales, the 23 features a masthead sloop rig that allows it to carry a large genoa, making it a surprisingly capable performer in light air—a necessity for summer sailing in the Pacific Northwest.

According to historical editorial retrospectives by Pacific Yachting, the Crown series (which includes the 23) was noted for its balanced helm and ability to point high into the wind. The hull's displacement-to-length ratio suggests a boat that favors stability over outright planing speed, providing a "big boat" feel that gives novice sailors confidence in heavy weather. However, owners frequently note that the spade rudder is highly sensitive; while this makes for an agile boat in tight marinas, it requires an attentive hand at the tiller when surfing downwind in a following sea.

Interior Comfort & Variations

For a 23-foot vessel designed in the 1970s, the Calgan 23 offers a remarkably functional, if snug, interior. The layout typically features a traditional V-berth forward, a small chemical or marine head situated under the cushions or in a dedicated locker, and two quarter berths that extend aft under the cockpit seats. The "Crown" branding often signified a step up in finishing compared to the more utilitarian Cal 20, incorporating more teak trim and molded fiberglass liners that simplified maintenance.

There were two primary variations in the deck mold. The standard version features a traditional cabin trunk that provides roughly 4'10" to 5' of headroom, while a rare "pop-top" variant was briefly produced to allow for standing headroom while at anchor. The Crown 23 shares its DNA with its larger sibling, the Crown 28, which was also a collaboration between Nairne and Lapworth. While the 23 lacks the full standing headroom and enclosed head of the 28, it retains the same aesthetic of clean lines and efficient use of space.

Known Issues & Buyer’s Checklist

Prospective buyers of a Calgan 23 should prioritize a thorough inspection of the deck and structural components, as these vessels are now entering their fifth decade of service.

  • Deck Delamination: Like many boats of this era, Calgan used balsa or plywood coring in the deck. Soft spots are common around the chainplates, stanchion bases, and the mast step. Any "springiness" underfoot usually indicates water intrusion and core rot.
  • Rudder Post and Bearing: The spade rudder is a high-stress point. Buyers should check for excessive play in the rudder post and inspect the fiberglass around the rudder tube for stress cracks or "crazing," which could indicate an impact or structural fatigue.
  • Keel Bolts: The cast iron or lead keel is through-bolted to the hull. "The Vancouver Smile"—a hairline crack at the leading edge of the keel-to-hull joint—is common, but deeper rust weeping from the bolts may necessitate dropping the keel for a full bolt inspection.
  • Window Seals: The original aluminum-framed windows are notorious for leaking, which can lead to the rot of the interior teak bulkheads. Check the wood around the ports for dark staining or soft spots.

Community & Resources

The Calgan 23 remains a staple of the "Classic Plastic" community in British Columbia and Washington State. While there is no longer a formal factory association, technical support is often found through the Council of BC Yacht Clubs, where many long-term owners of Crown and Calgan vessels share maintenance records and original marketing brochures.

The Verdict

The Calgan 23 is an excellent entry-level keelboat for those who value structural integrity and sailing pedigree over modern amenities. It remains a "sailor's boat," offering better windward performance than most modern trailersailers.

Pros

  • Exceptional stability and stiffness for a 23-foot boat.
  • High-quality fiberglass lay-up typical of early Pacific Northwest builders.
  • Excellent light-air performance, making it ideal for coastal cruising.

Cons

  • Limited headroom and cramped quarters for extended cruising.
  • Age-related maintenance (deck core and window leaks) is almost guaranteed.
  • The fixed fin keel limits trailering options compared to swing-keel designs.
