Columbia 29 Mk II Information, Review, Specs

Sailing Performance & Handling

Under sail, the Columbia 29 Mk II exhibits the stately, predictable behavior typical of Sparkman & Stephens’ heavy-displacement hulls from this era. With a displacement of approximately 8,400 pounds and a ballast-to-displacement ratio exceeding 45%, the vessel is exceptionally "stiff," meaning it resists heeling and carries its momentum well through heavy chop. According to historical design records from Sparkman & Stephens, the hull features a long keel with a cutaway forefoot and a transom-hung rudder, a configuration that prioritizes directional stability over agility.

In light air, the Mk II can feel sluggish due to its high wetted surface area, requiring a generous genoa to keep moving. However, when the breeze freshens to 15–20 knots, the boat finds its stride. Owners often report that the Mk II tracks "as if on rails," allowing the helmsperson to leave the tiller for short periods without the boat wandering off course. Unlike modern fin-keel boats that can be "twitchy" or prone to rounding up in gusts, the Mk II’s full-keel lineage ensures a slow, controlled motion that reduces crew fatigue during offshore passages. While it will not win modern windward-leeward races, its sea-kindliness makes it a favorite for those venturing into the heavy swells of the Pacific Coast or the choppy waters of the Chesapeake.

Interior Comfort & Variations

The primary distinction of the Mk II is its "Raised Deck" architecture, which drastically improved the living experience over the Mk I and the flush-decked "Defender" variant. This design allows for nearly six feet of headroom throughout much of the main cabin, a rarity for a 29-foot boat designed in the early 1960s. The layout is a classic of the era: a forward V-berth followed by a marine head (typically to port) and a hanging locker. The main salon features a settee that converts into a berth, and a galley situated near the companionway for optimal ventilation.

Columbia utilized a mix of fiberglass liners and mahogany or teak trim, creating an interior that feels more substantial than many modern "light and bright" production boats. It is important to note the sibling variations: the Columbia 29 "Defender" was a specialized version featuring a flush deck, intended for racing or those who preferred a massive foredeck area, though it sacrificed significant interior headroom. Later, as Columbia Yachts integrated with Coronado, some design elements were shared with the Coronado 30, though the 29 Mk II remains the more coveted model due to the Sparkman & Stephens name and the specific "over-built" layup schedules practiced at the California plants during its production peak.

Known Issues & Buyer’s Checklist

Prospective buyers of a Columbia 29 Mk II must account for the boat’s age, as most hulls are now over 50 years old.

• Deck Core Saturation: Like many boats of this era, Columbia used balsa or plywood coring in the decks. Over decades, leaking stanchion bases or chainplates often allow water to ingress, leading to soft spots. A thorough "percussion test" with a phenolic hammer is essential during inspection.
• Chainplate Bulkheads: The chainplates on the Mk II are bolted to plywood bulkheads. If the deck seals have failed, these bulkheads can rot invisibly behind the cabinetry, compromising the structural integrity of the rig.
• The "Atomic 4" Engine: Many Mk IIs were originally equipped with the Universal Atomic 4 gasoline engine. While reliable if maintained, buyers should check for manifold corrosion and fuel system safety. Many have since been repowered with Yanmar or Beta diesels, which significantly increases the vessel's value.
• Rudder Play: The transom-hung rudder is robust, but the gudgeons and pintles (the hinges) can wear down over time, leading to a "clunking" sensation in the tiller. These are relatively simple to replace but are a common point of neglect.

Community & Resources

The legacy of the Columbia 29 is supported by a dedicated group of enthusiasts. The Columbia Yacht Owners Association remains the primary repository for technical manuals, original brochures, and hull-specific advice. While the original company ceased operations in the late 1970s before its eventual resurrection for sportboats, the "Old School" Columbia community provides a wealth of knowledge on restoring these Sparkman & Stephens classics to their former glory.

The Verdict

The Columbia 29 Mk II is a "tank" of a sailboat that offers a secure entry point into coastal cruising for those on a budget. It trades modern speed and "dock appeal" for rugged construction and a world-class design pedigree.

Pros:

• Exceptional heavy-weather stability and tracking.
• Sparkman & Stephens design heritage ensures balanced handling.
• Impressive headroom and interior volume for its vintage.
• Robust fiberglass layup that is more "forgiving" of minor groundings than modern hulls.

Cons:

• Sub-par light-wind performance due to high wetted surface.
• Aged systems (plumbing, electrical, and gas engines) often require total overhauls.
• The "bubble top" styling is less aesthetically traditional than the Mk I or Defender models.
