The Gunfleet 58 represents a pinnacle of modern British offshore design, conceived by Richard Matthews as a refined, performance-oriented alternative to the traditional heavy-displacement cruisers of his former shipyard, Oyster. Designed by Tony Castro, the 58-footer was built to bridge the gap between high-latitude capability and the shallow-water versatility required for the Bahamas or the East Coast of the United States. Its defining characteristic is a sophisticated hydraulic lifting keel, which allows the draft to vary from a deep 3.6 meters (11'10") for upwind tracking to a remarkably shallow 1.75 meters (5'9") for coastal exploration. This engineering feat, combined with a sleek, contemporary aesthetic and a robust carbon-reinforced hull, positions the Gunfleet 58 as a premier choice for experienced shorthanded couples seeking a "go-anywhere" vessel without sacrificing speed or luxury.

Sailing Performance & Handling
On the water, the Gunfleet 58 defies the sluggish reputation often associated with high-volume center-cockpit cruisers. The hull features a relatively flat aft section and a plumb bow, maximizing the waterline length and reducing drag. According to editorial testing by Sail Magazine, which named the vessel a "Best Boats" winner in 2014, the yacht demonstrates impressive agility for its displacement, responding quickly to the helm even in light airs. This responsiveness is largely attributed to the twin-rudder configuration, which maintains exceptional grip and control when the boat is heeled, a necessary design choice to accommodate the shallow draft of the lifting keel.
The sail plan is typically configured as a Solent rig, featuring a large reacher for light air and a self-tacking jib for upwind efficiency. This setup allows for easy sail handling from the safety of the cockpit, which is equipped with powered winches and a "push-button" sailing philosophy. The inclusion of a standard carbon-fiber bowsprit facilitates the use of an asymmetric spinnaker or Code 0, further enhancing light-wind performance. Owners often report that the boat feels stiff and secure in a seaway, with the deep keel providing a low center of gravity that minimizes rolling and enhances comfort during long passages.
Interior Comfort & Variations
The interior of the Gunfleet 58 is a masterclass in modern joinery and ergonomic layout, typically finished in light oak or traditional teak to a superyacht standard. The centerpiece is the raised deck saloon, which features large wrap-around windows that flood the living space with natural light and offer panoramic views while seated. The galley is located in the starboard walkway leading aft, providing a safe, "U-shaped" workspace that remains functional even in heavy seas.
Accommodation is generally centered around a palatial owner’s stateroom aft, which utilizes the full beam of the boat and includes a private en-suite head and a dedicated desk or dressing table. Forward of the saloon, the VIP guest cabin offers a large island berth, while a third twin-bunk cabin provides additional space for crew or children. Some variants were built with a four-cabin layout, though the three-cabin configuration is more common among private owners. The Gunfleet 58 shares its design DNA with its smaller sibling, the Gunfleet 43, and its larger counterpart, the Gunfleet 74, maintaining a consistent focus on high-quality stainless steel work and recessed lighting across the range.
Popular Mentions & Media
The Gunfleet 58 gained significant international attention shortly after its launch, notably winning the "Flagship" category in the 2014 Sail Magazine Best Boats awards and receiving a nomination for European Yacht of the Year. Its reputation as a high-tech, versatile cruiser was further cemented by editorial coverage in Yachting World, where it was praised for its "uncompromising" approach to engineering and its ability to compete with established luxury brands like Swan or Contest.
Known Issues & Buyer’s Checklist
Prospective buyers of a Gunfleet 58 should focus their surveys on the specialized systems that distinguish this model.
- Hydraulic Keel Mechanism: The lifting keel is the boat's most complex component. Ensure the hydraulic rams show no signs of leakage and that the stainless steel keel foil is free of corrosion. The emergency manual override system should be tested during the sea trial.
- Twin Rudder Alignment: Due to the twin rudder setup, any play in the linkage can lead to "hunting" or vibration at high speeds. Inspect the steering quadrants and bushings for wear.
- Complex Systems Integration: As a "push-button" yacht, the 58 relies heavily on its DC power system and hydraulic manifold. Buyers should verify the age of the battery banks and ensure that all electrical solenoids for the winches and furling gear are operational.
- Teak Deck Integrity: Gunfleet used high-quality vacuum-bonded teak, but like any vessel of this age, the caulking should be inspected for shrinkage or lifting, which can lead to moisture ingress if ignored.
Community & Resources
While Gunfleet Marine produced a limited number of hulls compared to mass-market builders, a dedicated community exists through the Windboats Marine legacy. Technical support and original build records are often accessible via the craftsmen at Fox’s Marina & Boatyard in Ipswich, where the yachts were commissioned. Owners also frequently interact through the Ocean Cruising Club (OCC), as many Gunfleet 58s are actively used for transoceanic rallies and global circumnavigations.
The Verdict
The Gunfleet 58 is a sophisticated, high-performance bluewater yacht that offers a rare combination of deep-keel sailing dynamics and shallow-draft versatility. While its complexity requires diligent maintenance, the rewards are a vessel that is as comfortable in a remote coral lagoon as it is crossing the Atlantic.
Pros:
- Variable draft (1.75m to 3.6m) offers unparalleled cruising flexibility.
- Exceptional build quality and interior finish provided by Windboats.
- Balanced handling thanks to the Tony Castro hull and twin rudders.
- Modern, light-filled interior with excellent ventilation.
Cons:
- High system complexity requires an experienced owner or professional maintenance.
- Limited number of hulls on the brokerage market due to bespoke production.
- Twin rudders can be more vulnerable to lobster pots and debris compared to a skeg-hung rudder.
