The Columbia 50, introduced in late 1965, was a watershed moment in American yacht building, marking the arrival of the first large-scale production fiberglass sailing yacht. Designed by the legendary William H. Tripp Jr., this 50-foot vessel was built by the Columbia Yacht Corporation during an era when wood was still the primary material for yachts of this stature. Its debut signaled a shift in the industry, proving that fiberglass could provide the strength and luxury of custom builds at a production scale. As noted by the Columbia Yachts historical archive, the boat was often cited as the flagship of the line, combining a high-performance underbody with what was considered at the time to be the height of offshore luxury. Over its production life, which extended into the early 1970s (with later kit versions built through the early 1980s), approximately 60 hulls were completed, primarily at the company’s California facility.

The design is quintessential "Tripp," characterized by long, elegant overhangs, a low-profile cabin house—often referred to as the "bubble top"—and a graceful sheerline. While its aesthetic harkens back to the classic Cruising Club of America (CCA) rating era, its hull form was revolutionary, featuring a high-aspect fin keel and a separate spade rudder. This configuration, found on iconic racers of the same period like the Cal 40, was a bold departure from the full-keel designs common in the mid-1960s.
Sailing Performance & Handling
The Columbia 50 was conceived as a racer-cruiser capable of holding its own in the most competitive ocean circuits of the day. With a displacement of approximately 32,000 lbs and a lead ballast of 14,600 lbs, the vessel maintains a high ballast-to-displacement ratio of nearly 45%, providing significant stiffness and stability in a blow. According to technical specifications provided by the Columbia 50 community, the boat’s 33’ 3” waterline is designed to "lengthen" as the boat heels, increasing its hull speed when reaching or beating.
Under sail, the boat is known for a steady, predictable helm and a sea-kindly motion that minimizes fatigue during long offshore passages. Unlike lighter modern "surfers," the Columbia 50 is a displacement-driven hull that slices through chop rather than bouncing over it. Historical race results underscore this capability; the model won its class in the 1967 Transpac and took first overall in the 1966 Newport-Ensenada Race against a field of over 500 boats. While its performance upwind is strong due to the deep fin keel, its heavy displacement means it requires more wind to get moving in light air compared to contemporary sportboats, though its low wetted surface area helps it maintain momentum once established.
Interior Comfort & Variations
The interior of the Columbia 50 was designed for serious offshore work, emphasizing safety at sea while providing a level of craftsmanship that mirrored the era's custom wooden yachts. The standard layout typically includes a master stateroom forward with its own head, a spacious main salon with multiple settee berths, and a second stateroom or navigation area aft. The use of hand-finished teak and mahogany throughout the cabin creates a warm, traditional atmosphere that has aged well.
Because Columbia Yachts offered several variations, the onboard experience can differ significantly between hulls. The most famous variant is the "Flush Deck" model, which provides an expansive, uncluttered deck area for sail handling and lounging, at the expense of slightly less interior headroom compared to the "Trunk Cabin" version. Additionally, the hull served as the foundation for the Columbia 52, a "muscle boat" variant built for the later International Offshore Rule (IOR) with a taller mast and deeper keel. Owners who sought more control over the build process could purchase the vessel as a Sailcrafter 50, a kit version provided by Columbia that allowed for highly customized interior layouts.
Popular Mentions & Media
The Columbia 50 has a storied cultural footprint, having been owned and sailed by some of the most influential figures in the yachting world. Most notably, world-renowned cruising experts Steve and Linda Dashew circumnavigated on their Columbia 50, Intermezzo, a voyage that informed much of their later pioneering work in yacht design. The boat’s status as a "modern classic" was further cemented when American Sailing recognized it as a pioneer design that democratized large-boat sailing. Famous hulls like Simoon and Pace III are still remembered in racing circles for their dominance in the late 1960s Southern Ocean Racing Circuit (SORC) and Great Lakes events.
Known Issues & Buyer’s Checklist
Prospective buyers must approach a 50-year-old fiberglass vessel with technical scrutiny, specifically focusing on the materials and engineering of the 1960s.
- Deck Delamination: Like many boats of this era, the Columbia 50 utilizes a balsa-cored deck. If hardware was not properly bedded or was added later without sealing, water ingress can rot the core. Soft spots around stanchions and the mast step are high-priority inspection areas.
- Rudder Assembly: The spade rudder was an early implementation for a boat of this size. Inspectors should check the rudder post and internal framework for signs of corrosion or play, as original engineering may not have accounted for the long-term stresses of decades of offshore use.
- Chainplates and Rigging: The stainless steel chainplates are often original and, given the age, may be subject to crevice corrosion where they pass through the deck.
- Original Wiring: Most Columbia 50s were built with glass fuses and non-tinned copper wiring. A full electrical refit is almost always necessary to meet modern safety standards and support contemporary electronics.
- Keel Bolts: While the hull is robustly overbuilt, the condition of the keel bolts and the joint between the lead ballast and the fiberglass stub should be verified for any signs of movement or weeping.
Community & Resources
The longevity of the model is supported by a dedicated community of owners who maintain technical archives and restoration logs. The most prominent resource is the Columbia 50 Owners' Network, which maintains a technical wiki and registry for the remaining hulls. Additionally, the archival site columbia-yachts.com serves as a central repository for original brochures, sail plans, and designer notes.
The Verdict
The Columbia 50 remains one of the most aesthetically pleasing and seaworthy yachts of the fiberglass era, offering a blend of classic lines and legitimate offshore pedigree that modern production boats rarely match.
Pros:
- Timeless Aesthetics: The Bill Tripp design is widely considered one of the most beautiful hulls ever produced in fiberglass.
- Robust Construction: The hull laminate is thick and "overbuilt" by modern standards, offering great peace of mind in heavy seas.
- Proven Pedigree: A winner of legendary races like the Transpac and Chicago-Mackinac, it is a boat with true history.
- Deck Space: The flush-deck version offers unparalleled deck real estate for a 50-footer.
Cons:
- Maintenance Requirements: As a vintage yacht, systems are often outdated and require significant investment to modernize.
- Manueverability: The separate rudder helps, but her displacement and long overhangs make tight-quarters maneuvering in modern marinas more challenging than a modern fin-keel yacht.
- Depth and Draft: With a draft of nearly 7 feet, she is restricted in some shallower cruising grounds.
