Design Brief & Intent
The Fast 345 T was designed for the yachtsman who refuses to sacrifice sailing performance for cruising comfort. While competitors of the era from North America and Europe often favored wider, flatter hulls designed to maximize interior volume at the expense of upwind capability, Ron Holland utilized a deep-fin keel, a high-freeboard profile, and a balanced hull form to ensure exceptional sea manners. The hull was constructed of hand-laid fiberglass, with vacuum-bagging techniques applied to optimize the resin-to-glass ratio, creating a robust, durable structure. This focus on structural integrity earned the boat a reputation as a highly dependable cruiser. The layout was optimized for active sailing, positioning the nav station and galley close to the companionway for easy communication with the cockpit.
Sailing Performance & Handling
With a displacement of 11,500 pounds and a waterline length of 29.5 feet, the Fast 345 T features a displacement-to-length ratio of 199.98, placing it firmly in the medium-light displacement category. Driven by a high-aspect fractional sloop rig, the yacht carries a sail area to displacement ratio of 17.3, giving it excellent light-wind performance and the ability to glide through light air where heavier cruising designs stall. Under sail, the boat is remarkably stiff and stable, thanks to a robust ballast-to-displacement ratio of 38.26%, supported by a 4,400-pound lead fin keel.
At the helm, the Fast 345 T exhibits the light, responsive characteristics that are the hallmark of Ron Holland’s racing designs. The balanced spade rudder provides excellent bite, preventing round-outs when sailing close-hauled or under spinnaker in a blow. Upwind performance is arguably the boat's greatest strength; when properly tuned, the fractional rig allows the yacht to point exceptionally high while maintaining steady speed. A capsize screening ratio of 1.95 ensures that the yacht is well-suited for serious offshore passages. However, its comfort ratio of 23.52 indicates that while the hull is safe and stable, its motion in a heavy seaway will be more active and lively than that of a traditional, heavy-displacement full-keel cruiser.
Known Issues & Triage
The most significant and well-documented technical issue on the Fast 345 T relates to the keel-to-hull transition and the internal floor grid. Some production runs suffered from insufficient internal reinforcement in the bilge area surrounding the keel bolts. Surveyors and prospective buyers should look closely for "floor flex." In some units, when the boat is hauled out or placed on a cradle, the bottom of the hull has been observed to flex upward under the weight of the keel. This issue requires a structural upgrade, typically involving the lamination of additional, deep transverse floor timbers to properly distribute the immense loads of the 4,400-pound fin keel.
The standard auxiliary engine on many of these builds was a Pathfinder diesel. Based on a robust Volkswagen industrial block, the base engine mechanicals are highly reliable and easy to service. However, sourcing replacement marine-specific components—such as the heat exchanger, raw-water pump bracket, and exhaust elbow—can be exceptionally difficult today. Any prospective buyer should carefully inspect the cooling system and exhaust path for corrosion, as custom fabrication may be required if these components fail.
Modernization & Upgrades
Due to the age of the fleet, modernizing the electrical and mechanical systems is a common path for dedicated owners. The original electrical wiring and panel are typically overdue for replacement. A popular refit involves removing the heavy, lead-acid house battery banks and installing compact Lithium Iron Phosphate (LiFePO4) batteries. Because the Fast 345 T has a relatively modest original fuel capacity of 31 gallons and a freshwater capacity of 42 gallons, modern cruisers often install high-efficiency solar arrays. These are typically mounted on a custom stainless steel stern targa or gantry, which can also serve as a mounting point for a modern dinghy davit system.
For owners looking to undertake a complete repower, replacing the aging Pathfinder engine with a modern, lightweight diesel (such as a 30-horsepower Yanmar or Volvo Penta) greatly improves fuel efficiency, reduces vibration, and ensures ready access to spare parts worldwide.
The Verdict
The Fast 345 T is a classic of the South American cruiser-racer boom of the 1980s, offering a rare blend of true offshore capability, lively sailing performance, and a beautifully crafted interior. While it requires a careful survey—particularly regarding the keel floor reinforcement—it remains an exceptional value for sailors who appreciate the sailing characteristics of a high-performance Ron Holland design.
- Outstanding upwind sailing performance with a light, responsive helm
- Generous cabin headroom of six feet and five inches, rare for a 34-foot performance hull
- Beautiful, high-quality interior woodwork and joinery
- Highly capable offshore hull with a reassuring capsize screening ratio
- Critical need to inspect and potentially reinforce the keel-to-hull joints and internal floor grid
- Replacement marine parts for the original Pathfinder engine are difficult to source
- Limited standard fresh water and fuel capacities for long-range cruising
- Hand-tight cockpit layout makes single-handed sailing difficult without routing lines aft
