The Gunfleet 43 arrived on the international sailing scene in 2011 as the debut vessel of Gunfleet Marine, the second major yachting venture from industry veteran Richard Matthews. Following his departure from Oyster Yachts, Matthews sought to refine the "blue water cruiser" concept by integrating contemporary performance characteristics with the shallowwater versatility of a variable draft keel. Designed by the renowned Tony Castro, the 43 was engineered to provide the "pocket superyacht" experience—delivering the heavyweather capability and luxury finish typically reserved for 50footplus vessels within a more manageable 44foot1inch (13.43m) footprint. Built by Windboats in Norfolk, England, the hull utilizes a sophisticated laminate schedule including Kevlar reinforcements in the forward sections for impact resistance, signaling its intent as a serious ocean passagemaker.

Sailing Performance & Handling

The Gunfleet 43 distinguishes itself from traditional heavy-displacement cruisers through its Tony Castro-designed hull, which features a flatter, more modern underbody and a relatively generous beam that is carried well aft. This design choice, combined with a standard twin-rudder configuration, ensures the boat remains controllable and responsive even when pressed hard or sailing at significant heel angles. According to editorial testing by Yachting Monthly, the yacht exhibits a "slippery" feel through the water, accelerating quickly in light airs where older cruiser designs might struggle.

A defining technical characteristic is the hydraulic lifting centerboard. With the board fully extended to approximately 2.7 meters, the Gunfleet 43 gains a high-aspect-ratio foil that provides excellent lift and tracking for upwind work. When retracted to just 1.35 meters, it allows the yacht to enter shallow anchorages and estuaries that are typically off-limits to deep-keeled bluewater boats. The displacement-to-length ratio is moderate, ensuring enough mass to punch through a head sea without the "hobby-horsing" associated with lighter hulls. The sail plan is often configured as a Solent rig, featuring a large reaching genoa and a smaller, self-tacking jib for ease of handling when short-handed.

Interior Comfort & Variations

The interior of the Gunfleet 43 is built to a standard that reflects its premium market positioning, utilizing high-grade hardwoods like American cherry or light oak. As a center-cockpit design, the layout prioritizes the owner’s experience, centered around a palatial aft stateroom. This cabin typically features a large island berth, extensive hanging lockers, and an en-suite head with a separate shower stall—a rarity in a 43-foot hull. Sail Magazine noted the "superb joinery" and the abundance of natural light provided by the sleek, wrap-around deck saloon windows.

The main saloon utilizes a raised seating area to allow for "deck saloon" views while seated, though the coachroof profile remains low and sporty. The galley is typically arranged in the walk-through to the aft cabin, providing a secure, linear workspace for cooking at sea. While most 43s were built with a two-cabin, two-head layout to maximize luxury for a cruising couple, the semi-custom nature of the build allowed for slight variations in nav station size and storage configurations. The Gunfleet 43’s larger sibling, the Gunfleet 58, shares this design language but expands the layout to include a dedicated VIP forward cabin and additional guest quarters, though the 43 remains the primary choice for those seeking a "no-compromise" yacht for solo or couple-only operation.

Known Issues & Buyer’s Checklist

Prospective buyers of a pre-owned Gunfleet 43 should focus their surveys on the specialized systems that differentiate this model from simpler cruisers.

  1. Keel Hydraulic System: The lifting centerboard relies on a hydraulic ram and electronic controls. Inspectors should check the ram for leaks, the condition of the hydraulic hoses, and the pivot pin for any signs of lateral play or "clunking" while underway.
  2. Twin Rudder Alignment: Because the twin rudders are high-performance foils, any slight misalignment can lead to increased drag or a heavy helm. Check the steering linkages and bearings for smoothness.
  3. Deck Core and Hardware: The Gunfleet 43 features high-end deck hardware and often teak-laid decks. Ensure that all through-deck fittings remain well-sealed, as the composite deck structure must be kept dry to maintain its integrity.
  4. Complex Electrical Systems: These boats were often heavily optioned with electric winches, bow thrusters, and sophisticated navigation suites. A thorough sea trial should include a "load test" of the battery banks and a verification of the charging systems (alternators and chargers).

Community & Resources

While Gunfleet Marine production was limited compared to mass-market brands, the boats are supported by a dedicated network. Fox’s Marina & Boatyard in Ipswich, where the yachts were originally commissioned, remains a primary technical resource for owners seeking original specifications or specialized maintenance for the lifting keel systems. Owners often interact through high-end cruising groups, though there is no large-scale public "owners association" due to the low hull numbers; instead, support is typically handled directly through the shipyard's legacy contacts at Windboats.

The Verdict

The Gunfleet 43 is a meticulously engineered cruiser that successfully bridges the gap between high-performance naval architecture and the luxury requirements of long-distance liveaboards. It is best suited for experienced sailors who refuse to choose between a deep-draft performance profile and the ability to explore shallow coastal waters.

Pros:

  • Variable Draft: The 1.35m minimum draft offers exceptional coastal versatility.
  • Build Quality: Construction by Windboats ensures a level of finish and structural integrity comparable to the world's finest yards.
  • Handling: The Tony Castro hull and twin rudders provide a balanced, modern sailing experience.

Cons:

  • System Complexity: The hydraulic keel and high-end systems require more specialized maintenance than a fixed-keel yacht.
  • Limited Availability: Rare on the brokerage market due to limited production runs.
  • Weight: While performance-oriented, it is still a substantial cruising yacht and requires power winches for effortless sail handling.
