Our Thoughts

JAMMY is a 2015 Gunboat 57' designed by legendary naval architect Nigel Irens, representing one of the most extensively customized and performance-optimized examples of the Gunboat 57' platform. Built with a clear mandate for high-performance cruising capability paired with single-handed and short-handed sailing functionality, this one-owner vessel showcases purposeful engineering upgrades throughout her structure, propulsion, rigging, and systems that directly enhance her capabilities beyond the original design specification.

The hull and deck construction employs epoxy-infused carbon fiber monocoque with Corecell closed-cell foam coring—a lightweight, rigid approach that supports the vessel's performance requirements.

2015 Gunboat 57' – High-Performance Cruising Yacht with Racing Heritage in Newport, RI
Overview
JAMMY is a 2015 Gunboat 57' sailing yacht designed by the legendary Nigel Irens, representing a pinnacle of high-performance cruising design executed through extensive single-owner customization. This one-owner Gunboat 57' has been meticulously configured for capable short-handed and solo sailing, with a powerful sail plan engineered beyond the original specification and a suite of hydraulic controls, advanced navigation electronics, and premium interior finishes that reflect a serious commitment to both performance and comfort. The vessel's recent racing success—including a Block Island round-the-island record and an overall class win at the 2025 Block Island Race Week—demonstrates the effectiveness of her design optimization and build quality. Currently berthed in Newport , Rhode Island, JAMMY combines the lightweight carbon fiber construction and seaworthy hull form Gunboat is known for with custom reinforcement, modern Alexseal finishes applied in 2024, and a level of interior specification typically reserved for luxury cruising yachts.
Hull, Deck & Construction
JAMMY's structure employs epoxy-infused carbon fiber monocoque construction with Corecell closed-cell foam coring, a methodology that delivers exceptional strength-to-weight performance critical to sailing yacht efficiency. The hull is finished in Alexseal Fisherman's Blue Linear Polyurethane applied in 2024, while the deck and superstructure wear Alexseal Oyster White Linear Polyurethane in the same application year. Spars are finished in Flat Black matte Linear Polyurethane, creating visual distinction and reducing reflective glare at the masthead. A sacrificial "false" bow and forefoot provide impact protection during anchoring and docking operations—a practical addition that preserves the primary hull structure. Six flush-mounted Lewmar deck hatches offer ventilation and cabin access throughout the vessel, while hi-load tempered tinted glass windows forward and along the sides provide visibility while managing solar heat gain and UV exposure. The beam of 25 feet provides a spacious platform for deck operations and interior volume, while the carbon fiber construction keeps displacement low, a fundamental advantage in achieving the performance envelope for which Gunboat designs are recognized.
Spars, Rigging & Sail Plan
JAMMY's standing rigging was sent to the Future Fibers factory in Spain for inspection in 2023, and the custom Hall carbon fiber mast was ultrasound tested in the same year, confirming structural integrity and supporting confidence in heavy-air sailing. The mast was engineered for improved strength compared to the standard Gunboat 57' specification, a custom modification that underpins JAMMY's ability to carry 20% more sail area than the original Gunboat 55' design. The spars include a Hall carbon fiber Park Avenue boom, carbon fiber longeron, and a sophisticated furling system comprising a KZ Racing code furler, KZ Racing A3 furler, and Facnor solent furler—allowing flexible management of multiple headsails in varying wind conditions. Two Harken racing three-speed winches at the helm, coupled with Spinlock rope clutches, provide mechanical advantage and control for single-handed sail handling. A Harken Hydro-Two hydraulic power pack drives the hydraulic push-button main sheet with emergency release, reducing physical demand during sail trim and enabling responsive mainsail control. The Lewmar V5 hydraulic windlass with a Rocna 88-pound anchor and 130 feet of stainless steel chain rounds out the ground tackle system. The North Sails inventory includes a 3DI Endurance mainsail with three reefing points (2024), a 3DI J1 on furler (2024), a 3DI Solent jib (rebuilt 2023), a rebuilt screecher, and a downwind spinnaker in a sock—a comprehensive inventory supporting varied wind angles and conditions from light air to strong breeze.
Helm & Navigation Station
The helm station is finished in Oyster White Alexseal Linear Polyurethane and centers on a custom carbon fiber helm pedestal supporting a Jeffa Y-spoke carbon fiber steering wheel. The winch island integrates all sail-handling controls, while a custom Arrigoni helm seat mounted on an athwartship track allows adjustment for comfort during extended helm time. Navigation and autopilot capability is anchored by the B&G Hercules H5000 suite with performance package, including a B&G Zeus 12-inch multifunction chart plotter, 4G broadband radar scanner, dual B&G autopilots (switchable), B&G Halcyon 3-axis sensor, B&G V-90 VHF, and B&G AIS module. Four B&G Zeus II screens distributed throughout the helm area provide redundancy and situational awareness. A Standard Horizon HX471S VHF serves as secondary communication. Dual depth and speed sensors feed real-time water data to the navigation suite, supporting accurate passage planning and performance monitoring. Two Yanmar engine control panels flank the chart plotter, while push-button daggerboard controls and push-button lighting controls streamline operations at the helm. An auto anchor windlass control with chain counter simplifies anchoring procedures, particularly valuable for single-handed operation. The B&G remote vision wireless autopilot controller allows helm management from the cockpit or salon, enhancing safety and reducing fatigue during long passages. The Echomax radar signal booster and side-scanning sonar expand situational awareness in poor visibility and support navigation in complex anchorages.
Main Salon & Galley
The main salon spans the bridge deck with a spacious footprint defined by tempered glass windows forward, port, and starboard, flooding the interior with natural light. Isin glass removable aft curtains provide privacy and sun control. The teak sole throughout the salon establishes a warm, traditional aesthetic while offering durability and slip resistance. A port dinette with seating for six faces a large athwartship seating area aft that accommodates an additional six, creating flexible entertaining and dining configurations. The custom Arrigoni helm seat on an athwartship track doubles as additional seating when the vessel is anchored or moored. The galley features white marble-style Corian countertops throughout, with teak cabinet faces providing visual warmth and structural integrity. Two Miele refrigerator drawers and two Miele freezer drawers offer cold storage for extended cruising, while a Miele 4-burner propane stove and Thermador combination convection/microwave oven support varied cooking methods.
