Columbia 43 CB Information, Review, Specs

Sailing Performance & Handling

The Columbia 43 CB is a muscular, stiff performer that reflects the transition from the Cruising Club of America (CCA) to the International Offshore Rule (IOR). With a substantial ballast-to-displacement ratio approaching 50%, the boat is notably "stiff," meaning it resists heeling even in heavy gusts. When sailing upwind with the centerboard fully extended to its 10'3" depth, the 43 CB tracks with remarkable precision and exhibits significantly less leeway than its shallow-draft competitors. Conversely, retracting the board reduces the draft to a mere 4'11", making it one of the few 40-plus-foot yachts of its era capable of entering thin-water anchorages.

Editorial reviews in Sailing Magazine describe the boat as having a "performance edge" on paper due to its high sail area-to-displacement ratio (approximately 18.2). Owners report that while the 43 can be a handful in heavy air if over-canvassed, reefing early preserves both speed and comfort. Its racing pedigree is well-documented; the Columbia 43 Encore famously won its class in the 1971 Transpac race to Honolulu, proving the hull’s capability for sustained high-speed ocean passages.

Interior Comfort & Variations

The flush-deck design of the 43 CB creates an interior volume that was revolutionary for its time, often described by contemporary reviewers as feeling "more like a condo than a boat." The absence of a traditional trunk cabin allows for 6'4" of headroom throughout much of the main salon. The standard layout features a massive U-shaped dinette to starboard and a high-functioning galley to port, equipped with double sinks and extensive icebox capacity.

The Columbia 43 was produced in several distinct iterations. The Mark I featured a fixed iron fin keel (6'11" draft), while the rarer Mark III, introduced around 1973, featured a six-inch bow extension, a taller mast, and a lead keel for improved IOR rating performance. A notable sibling to the 43 is the Coronado 45, which utilized the same Bill Tripp hull but replaced the flush deck with a high-profile center-cockpit deckhouse to cater specifically to the live-aboard cruising market.

Popular Mentions & Media

The Columbia 43 has maintained a persistent cultural presence in the sailing world, partly due to its aggressive 1970s marketing campaigns that compared its sleek lines to a fighter plane. Beyond its racing triumphs in the Transpac and the Newport to Ensenada races, the model is well-known in the Caribbean via the yacht Tranquilo in Aruba. As detailed by Sailing Magazine, this specific Columbia 43 has performed daily commercial charters for over 40 years, a testament to the hull's durability under extreme duty cycles.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Columbia 43 CB with a focus on the structural and systems-grade issues common to Whittaker-era production.

• Deck Core Integrity: Like many boats of this vintage, the 43 used a balsa-cored deck. Moisture intrusion around stanchion bases and the mast step can lead to significant delamination and "soft spots."
• Centerboard Mechanism: The "CB" model requires specific inspection of the centerboard trunk, the pivot pin, and the stainless steel pennant (cable). These components can suffer from corrosion or fouling if not regularly serviced.
• Whittaker-Era Plumbing & Wiring: Early models were notorious for using non-marine-grade components, including gate valves instead of proper seacocks and residential-style wiring. Most surviving examples have been retrofitted, but any original systems should be replaced immediately.
• Hull "Oil Canning": While the 43 mostly avoided the thinning issues of smaller Columbia models, buyers should inspect the hull for any signs of excessive flex or "oil canning" near the bulkheads, especially in boats that were raced hard.
• Engine Upgrades: Many 43s originally shipped with underpowered Palmer gasoline engines. A diesel conversion (typically to a Perkins or Westerbeke) is a high-value upgrade to look for in the secondary market.

Community & Resources

The primary hub for technical data and owner support is the Columbia Yacht Owners Association. This group maintains archives of original brochures, technical drawings for the centerboard assembly, and historical production records that help owners distinguish between the various Mark I, II, and III variants.

The Verdict

The Columbia 43 CB is a rare "dual-threat" classic: a legitimate ocean racer with the shallow-water freedom of a small coastal cruiser.

Pros

• Exceptional Draft Versatility: The 4'11" board-up draft is nearly unheard of for a boat with this much offshore capability.
• Interior Volume: The flush-deck design offers a spacious, airy cabin that outperforms many modern 40-footers in terms of headroom and light.
• Robust Hull: Hand-laid fiberglass construction provides a solid, confidence-inspiring feel in heavy weather.

Cons

• Maintenance Intensive: The centerboard adds a layer of mechanical complexity and potential failure points.
• Vintage Systems: Original wiring and plumbing are often substandard and require modernization.
• Deck Issues: Large, flat deck areas are prone to balsa core rot if hardware is not meticulously re-bedded.
