Columbia 34 Mk II CB Information, Review, Specs

Sailing Performance & Handling

The Columbia 34 Mk II CB is defined by its stiffness and its ability to carry sail in heavy weather. With a displacement of approximately 12,000 pounds and a generous beam of 10 feet, the hull offers significant form stability. Unlike the standard fin-keel version which draws 5’6”, the Centerboard variant draws only 3’9” with the board up, allowing it to navigate coastal shoals with ease. When the board is fully extended to its 8’0” depth, the boat gains a significant advantage in upwind tracking and reduced leeway, though it lacks some of the ultimate pointing ability found in pure racing designs of the era.

Handling is generally described as predictable, though the high freeboard and wedge-deck design can make the boat wind-prone during low-speed docking maneuvers. Under sail, the Tripp-designed hull is known for being "dry," as the flared bow deflects spray effectively. According to technical documentation from the Columbia Yacht Owners Association, the Mk II was designed to be a "high-performance cruiser," balancing a respectable Sail Area/Displacement ratio with the ruggedness required for offshore passages. Owners often report that while the boat is not a light-air flyer, it comes alive in 15 to 20 knots of breeze, maintaining a steady helm and a comfortable motion in a seaway.

Interior Comfort & Variations

The interior of the Columbia 34 Mk II CB is perhaps its most famous feature, boasting a remarkable 7 feet of headroom—a feat rarely achieved in a 34-foot vessel even today. The "wedge-deck" design allows this height to carry well forward into the saloon, creating an airy, cavernous atmosphere. The layout typically features a large V-berth forward, a wrap-around dinette that converts to a double berth, and a linear galley. The use of faux-wood laminates and teak trim was standard for the period, prioritizing durability and ease of maintenance.

Sibling variations are significant for this hull. The most common is the standard fin-keel Mk II, which shares the same deck and interior but lacks the centerboard trunk that slightly bisects the cabin sole in the CB version. Furthermore, the Whittaker Corporation (Columbia’s parent company at the time) utilized a nearly identical hull mold for the Coronado 35. While the Columbia version was marketed as a sleeker, performance-minded aft-cockpit boat, the Coronado 35 sibling was configured as a center-cockpit cruiser with a private aft cabin, catering to families seeking maximum privacy over sailing lines.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Columbia 34 Mk II CB with a focus on structural integrity, particularly regarding the materials used during the 1970s production boom.

• The "Columbia Smile": Like many boats of this era with external lead ballast, a hairline crack can develop at the forward joint where the keel meets the hull (often called the "Columbia Smile"). While often cosmetic, it should be inspected for evidence of keel bolt movement or structural fatigue.
• Centerboard Mechanism: The pendant and pivot pin for the centerboard are critical failure points. If the board has not been serviced, it may seize in the up or down position. Buyers should verify the board's operation while the boat is hauled out to check for excessive play or "clunking" in the trunk.
• Deck Delamination: Columbia used balsa-coring in the decks. Over decades, water intrusion around stanchion bases or the mast step can lead to soft spots. A thorough percussion test (hammer sounding) of the deck is essential.
• Chainplates: The chainplates on the Mk II are often glassed into the hull or hidden behind cabinetry. Signs of rust streaks or "bleeding" on the interior liners indicate a need for immediate re-bedding to prevent bulkhead rot.

Community & Resources

The primary hub for technical support and historical data is the Columbia Yacht Owners Association, which maintains an extensive archive of original brochures, sail plans, and modification guides specifically for the 34 Mk II. This community is particularly active in documenting the transition of these boats from 1970s coastal cruisers to modern "refit" candidates for budget-conscious offshore sailors.

The Verdict

The Columbia 34 Mk II CB is a robust, "voluminous" cruiser that punches well above its weight class in terms of living space and shallow-water versatility.

Pros

• Massive Interior: The 7-foot headroom is unmatched in this size and vintage.
• Shallow Draft: The 3’9” board-up draft opens up cruising grounds inaccessible to most 34-footers.
• Sturdy Construction: Built during an era of heavy fiberglass layups, the hull is inherently strong.

Cons

• High Freeboard: The "wedge" look is polarizing and can make the boat catch the wind in tight marinas.
• Aesthetic Aging: The heavy use of 1970s-era plastics and laminates in the interior can feel dated without a significant refit.
• Maintenance Complexity: The centerboard system adds a layer of mechanical maintenance not found on the fin-keel version.
