Westsail 43 Information, Review, Specs

Sailing Performance & Handling

The Westsail 43 is a quintessential heavy-displacement cruiser, displacing approximately 31,500 pounds with 11,000 pounds of lead ballast. This gives it a high displacement-to-length ratio, translating to a motion at sea that is often described as "stately." It does not bounce over waves; it punches through them. With a full keel and a protected rudder, the boat tracks exceptionally well, making it easy to balance under sail and reducing the strain on windvane steering systems during long offshore passages.

The sail area-to-displacement ratio (SA/D) sits in the "heavy cruiser" category, meaning the boat requires a stiff breeze to truly come alive. In light air (under 10 knots), the 43 can be sluggish, often requiring the iron sail to maintain progress. However, as documented by technical resources at Worldcruiser, the design’s true strength is revealed in 20+ knots of wind. Its ability to carry sail late into a building gale provides a sense of security that few modern, light-displacement yachts can match. Handling-wise, the 43 is typically rigged as a cutter or a ketch, allowing for a versatile array of sail combinations to keep the boat balanced as the wind increases.

Interior Comfort & Variations

Because the Westsail 43 was the aft-cockpit version of the 42 hull, the interior volume is cavernous, benefiting from the hull’s nearly 13-foot beam and significant freeboard. The layout typically features a large "U-shaped" galley and a dedicated navigation station near the companionway. Because so many of these vessels were finished by their original owners rather than the factory, no two interiors are identical. Common configurations include a large pullman berth forward or a traditional V-berth, with some owners opting for a dedicated workshop area—a luxury afforded by the 43's immense internal scale.

High-quality factory-finished boats featured extensive teak joinery, white laminate bulkheads for brightness, and massive storage lockers designed for multi-year voyaging. Headroom is generous, often exceeding 6'5" in the main saloon. The sibling model, the Westsail 42, offers a different living experience with a private aft cabin accessible via a walkthrough or separate cockpit entrance; the 43 sacrifices that private aft cabin for a larger cockpit and a more expansive, unified main living area.

Known Issues & Buyer’s Checklist

Prospective buyers must distinguish between factory-finished boats and owner-finished kits. The latter require a rigorous survey of the electrical and plumbing systems, as amateur installations vary wildly in quality.

A primary technical concern for Westsails of this era is the condition of the "black iron" fuel tanks. Many 43s were built with these tanks glassed into the hull; over decades, moisture can cause localized corrosion, leading to leaks that are notoriously difficult to repair without cutting into the cabin sole. Additionally, the chainplates—massive stainless steel straps—should be inspected for crevice corrosion where they pass through the deck. While the hulls are solid, hand-laid fiberglass and remarkably thick, the decks are plywood-cored. Any signs of "sponginess" or elevated moisture readings near stanchions or deck hardware indicate a need for core replacement, a labor-intensive project. Finally, the steering linkage on the aft-cockpit 43 should be checked for play, as the long cable runs or radial drives can wear over decades of use.

Community & Resources

The Westsail 43 benefits from one of the most robust owner support networks in the maritime world. The Westsail Owners Association maintains an extensive archive of original blueprints, manuals, and a "knowledge base" that addresses almost every conceivable repair. Furthermore, Bud Taplin—the former General Manager of Westsail—founded Worldcruiser, which remains the definitive source for specialized Westsail parts, including rudder hardware, replacement tanks, and original-spec castings.

The Verdict

The Westsail 43 is a "forever boat" for the sailor who prioritizes ultimate seaworthiness and carrying capacity over racing performance. It is a vessel designed to keep its crew safe in conditions that would turn back lighter yachts.

Pros:

• Massive Strength: Heavily built hull capable of withstanding significant impacts and extreme weather.
• Storage Capacity: Enormous volume for fuel, water, and provisions, ideal for remote cruising.
• Directional Stability: The full keel provides excellent tracking and a comfortable, predictable motion.
• Strong Resale & Community: A dedicated following ensures parts and advice are always available.

Cons:

• Light Air Performance: Struggles in light winds without significant sail area or engine assistance.
• Maneuverability: Like most full-keel boats, it is challenging to back up in tight marinas under power.
• Maintenance Variance: The "kit boat" legacy means buyers must be wary of inconsistent build quality in non-factory finishes.
