Tanton 45 Information, Review, Specs

Sailing Performance & Handling

The Tanton 45 is celebrated for its unconventional yet highly efficient sail plan, most notably the unstayed cat-ketch rig featuring carbon-fiber masts and wishbone booms. This configuration yields a high Sail Area to Displacement (SA/Disp) ratio of approximately 22.2, a figure that suggests exceptional light-air performance and acceleration rarely found in 45-foot cruising yachts. The lack of standing rigging—shrouds and stays—results in a remarkably "clean" aerodynamic profile and simplifies tacking, as there is no headsail to winch across the deck.

According to technical reviews on Boats.com, the boat’s Displacement to Length (D/L) ratio of roughly 189 places it in the "light-moderate" category, allowing it to surf in following seas where more traditional Ta Chiao models might wallow. The hull features a low-aspect fin keel and a large rudder mounted on a sturdy skeg, providing a balance between maneuverability in tight marinas and directional stability offshore. While the cat-ketch rig excels on a reach and downwind, some owners have opted for a more conventional cutter rig, which offers better upwind pointing at the cost of the cat-ketch’s simplicity and ease of shorthanded handling.

Interior Comfort & Variations

Consistent with Ta Chiao’s reputation, the interior of the Tanton 45 is a showcase of Burmese teak joinery and traditional craftsmanship. The layout generally focuses on long-term liveability for a couple or a small family. Because the boat features a flush deck or a very low-profile coachroof, the interior feels expansive, though this design choice requires careful placement of hatches to ensure adequate ventilation.

Most hulls were configured with a large owner’s stateroom aft and a V-berth forward, separated by a spacious main salon. The galley is typically positioned in the passageway or at the base of the companionway, providing a secure location to brace oneself while cooking at sea. A notable variation in the Tanton lineage is the Tanton 43, which served as the hull's direct predecessor; while the 43 shared the same aesthetic, the 45 offers significantly more "payload" capacity and tankage, making it the preferred choice for transoceanic passages.

Popular Mentions & Media

The Tanton 45 gained notable recognition through its association with experienced offshore sailors and maritime authors. Most famously, hull number eight, originally named Bird of Time, was custom-built for author Don Dodds. The vessel served as a central case study in his influential book, Modern Cruising Under Sail, where it was presented as the definitive example of a modern, efficient cruising yacht. Dodds' endorsement of the Tanton design helped cement its reputation as a "thinking person's cruiser."

Known Issues & Buyer’s Checklist

Prospective buyers of a Tanton 45 should focus their inspections on the unique intersection of Taiwanese construction and Tanton’s technical specifications:

• Unstayed Mast Steps: On cat-ketch versions, the masts are unstayed and rely entirely on the integrity of the deck partners and the mast step. Inspect these areas for any signs of stress cracking or compression in the laminate.
• Teak Deck Longevity: Like many yachts of this era from the Ta Chiao yard, the Tanton 45 often featured screw-down teak decks. Over decades, the thousands of fasteners can become paths for water to enter the sub-deck core. Any "sponginess" or interior water staining on the overhead is a high-priority concern.
• Fuel and Water Tanks: Many Taiwanese builds from the 1980s used black iron for fuel tanks and stainless steel for water. These are often glassed into the structure, making replacement a major surgical undertaking if corrosion has set in.
• Carbon Fiber Fatigue: If the vessel is equipped with original carbon-fiber spars, they should be professionally surveyed for UV degradation or cracks, particularly near the exit points for halyards.

Community & Resources

While there is no single-model association, Tanton owners are often active within the broader "Taiwanese Boat" community. The Ta Chiao Owners Group provides a wealth of technical knowledge regarding the shipyard's specific construction methods and plumbing/electrical schematics. Additionally, the designer himself, Yves-Marie Tanton, has historically maintained an active presence through Tanton Yacht Design, providing original drawings and refit advice to owners of his heritage designs.

The Verdict

The Tanton 45 is a rare find that bridges the gap between the rugged "teak-and-heavy-glass" tradition of Taiwan and modern performance naval architecture. It is an ideal vessel for the sailor who prioritizes ease of handling and sailing speed over the traditional, slower motion of a full-keeled cruiser.

Pros:

• Ease of Handling: The cat-ketch rig is arguably the simplest sail plan for a solo or couple to manage on a 45-foot boat.
• Build Quality: Exceptional interior woodwork and a robust fiberglass layup.
• Innovation: Features carbon spars and unstayed rigs that were decades ahead of their time.

Cons:

• Complex Refits: Replacing unstayed masts or leaking fuel tanks can be significantly more expensive than on conventional yachts.
• Aesthetic Niche: The flush deck and double-ender appearance are polarizing and may not appeal to those seeking a contemporary "Euro-style" yacht.
