Our Take

The 2023 Granocean 57 represents a purposefully engineered offshore catamaran designed for extended cruising and serious bluewater capability. This 57-foot dual-hull platform, built to CE Area IIA standards and USCG documented, combines professional hull engineering by Howard Apollonio with structural verification by GURIT and interior design by the Dutch superyacht firm Vripack—a design pedigree that translates to seaworthiness, durability, and refined living spaces.

Propulsion & Performance

Twin Cummins QSB6.7 550-horsepower diesel engines with ZF280IV gearboxes deliver a maximum speed of 21 knots and provide the range necessary for serious distance cruising. With approximately 260 engine hours, the powerplants remain well within their service life. The long-range fuel capacity of 1,585 gallons (5,800 liters) supports extended passages: at 8 knots the vessel achieves roughly 2,100 nautical miles of range, at 10 knots approximately 1,140 nautical miles, and at cruising speed (10 knots) fuel consumption runs approximately 14 gallons per hour. The dual-engine configuration with independent systems, PSS shaft seals, Aqua 17 high-tensile shafts, and SeaStar hydraulic steering compatible with autopilot provides redundancy and reliability essential to offshore operation.

Hull & Structural Design

The composite fiberglass hull and deck employ closed-cell PVC foam and honeycomb core construction laminated to EN ISO 12215-5 structural standards, verified through HPI Verification Services. This lightweight composite approach reduces weight while maintaining structural integrity—a critical advantage in a 57-foot catamaran. The beam of 28.83 feet and four-foot draft suit protected waters and coastal cruising while the twin-hull design delivers inherent stability and reduced motion underway. White gelcoat exterior finish with International Interlux antifouling paint protects the underwater surfaces, and the vessel features fresh bottom paint applied in April 2026.

Accommodation & Interior Layout

Four generous staterooms provide sleeping capacity for extended family or charter operations. The owner's suite features a king-size berth, private head with shower, and dedicated vanity. Three additional guest cabins are appointed with queen-size berths and hi-low bunk options, each with ensuite heads featuring Corian countertops, Kohler ceramics, electric Tecma toilets, and separate shower compartments. A crew berth forward in the port bow offers additional flexibility. A day head positioned under the staircase to the flybridge, plus an aft deck day head, ensure guest convenience. Interior finishes include soft vinyl leather and wooden veneer with satin finish, hardwood flooring in the salon, cedar-lined hanging closets, and roll-down shades throughout.

The salon showcases panoramic views through large laminated fixed windows and Lewmar wide-opening sliding glass doors. A 50-inch Samsung flip-down television, Fusion RA770 entertainment system with speakers, and DC LED lighting create a comfortable gathering space. The U-shaped galley is equipped with a full-height Siemens refrigerator and freezer, three-burner electric convection cooktop, Siemens extraction hood, Siemens combination oven and microwave, double Kohler stainless steel sinks, and Corian countertops with ample storage. A wine fridge, dishwasher, and

2023 Granocean 57 Motor Yacht for Sale – Luxury Catamaran with Full Garmin Electronics and Extended Range
Overview
The 2023 Granocean 57 represents a contemporary approach to long-range cruising, combining European superyacht design principles with practical offshore capability. Built to CE standards with composite hull construction and designed by Howard Apollonio, this 57-foot catamaran is configured as a four-stateroom, five-head luxury motor yacht currently located in Hallandale Beach, Florida. The vessel features twin Cummins 550 HP diesel engines, a comprehensive Garmin navigation suite installed at both main helm and flybridge , and an extensive list of factory and owner-installed upgrades that reflect serious investment in comfort, safety, and operational capability. The owner's decision to order a larger model has made this lightly-used yacht available at $1,930,000. With approximately 260 engine hours, fresh bottom paint applied in April 2026, and USCG documentation complete, the Granocean 57 is positioned as a turnkey entry into the European-built catamaran market for buyers seeking proven design combined with modern systems integration.
Hull Design and Construction
The Granocean 57's hull employs a composite fiberglass infusion process with closed-cell PVC foam and honeycomb core materials, engineered to meet EN ISO 12215-5 structural standards and verified through HPI Verification services. This construction method balances weight distribution with structural integrity—particularly important for a 28.83-foot beam catamaran designed to maintain stability across varying sea states and loading conditions. The hull geometry, developed by naval architect Howard Apollonio, incorporates a design that supports the vessel's 10-knot cruising speed with a maximum velocity of 21 knots. At displacement cruising speeds, the catamaran's twin-hull configuration reduces pitching and roll, a characteristic that becomes increasingly valuable during extended offshore passages or when operating in moderate sea conditions. The gelcoat finish is white as standard, with the option for colored or painted hulls; this particular vessel retains the classic white exterior. Below the waterline, International Interlux antifouling paint provides protection against marine growth, while above-waterline through-hull fittings are 316 stainless steel and below-waterline fittings are bronze—both choices reflecting corrosion resistance appropriate to saltwater operation.
Deck Layout and Exterior Features
The main deck non-skid surface provides secure footing throughout, with eight heavy-duty 10-inch 316L stainless steel cleats positioned for mooring and two additional 6-inch pop-up cleats on the transom platform. The bow features a Lewmar V4 electric windlass with chain counter and foot switches, paired with a 50 kg stainless steel delta anchor and 100 meters of 12 mm G30 galvanized anchor chain. A Rocna 55 kg anchor (owner-installed upgrade) provides secondary ground tackle. Foredeck design emphasizes social use: large sunpads with Soffkin Kalmin marine vinyl cushions face forward, supplemented by a seating area and central storage locker with cup holders. An insulated icebox locker sits beneath the forward settee, while two large fender lockers are integrated below the sun pads. This layout transforms the bow into a dedicated relaxation and entertainment zone—a feature particularly valued during at-anchor periods or when moored in protected anchorages. The aft deck features a covered design with overhead LED lighting, creating a weather-protected gathering space. A large L-shaped settee with Soffkin vinyl cushions and storage beneath provides comfortable seating for multiple guests, while two teak cockpit dining tables support al fresco dining. A livewell with tank on the starboard aft deck indicates fishing capability, complemented by rod holders integrated into the cockpit design. A Kenyon electric grill mounted on the aft deck enables outdoor cooking, while a rain shower with hot and cold water at the port stern provides rinse capability. The transom platform includes LED flood lights and a stainless steel folding swimming ladder for water access. A hydraulic tender lift platform with 650 kg capacity is installed on the aft deck; retractable dinghy chocks are fitted, though no tender is included with the sale. A Steelhead ES1500 flybridge crane facilitates launch and recovery of a tender or dinghy, a practical feature for extended cruising where a secondary vessel enhances exploration and shore access.
Flybridge and Upper Deck Configuration
The flybridge is enclosed with acrylic windshield protection and features a complete helm station with double seats, steering, throttle, and integrated Garmin chart plotter, autopilot, and VHF radio. A wet bar with Corian countertop and built-in sink provides beverage service, while a large C-shaped settee accommodates approximately ten guests with Soffkin vinyl cushions and integrated storage. Two teak dining tables and sun lounges with storage complete the outdoor entertaining space. The enclosed flybridge option (selected on this vessel) adds significant year-round usability: a 16 kBTU Frigomar inverter air-conditioning unit maintains comfortable temperatures, while a dedicated head with Tecma electric toilet, sink, and shower compartment serves upper-deck guests. An exterior settee for two provides open-air seating when weather permits. The hardtop structure incorporates an instrument mast for navigation antenna placement and houses 300-watt solar panels with controller—a practical upgrade that extends battery charging capability during extended anchorages.
Helm Station and Navigation Electronics
The main helm station at the flybridge is equipped with a comprehensive Garmin package: a 12-inch chart plotter serves as the primary navigation display, supported by Garmin 20nm-36nm radome radar, Garmin depth/speed/fishfinder combo transducer, Garmin VHF radio, Garmin autopilot, and Garmin wind meter. Four exterior CCTV cameras provide 360-degree visibility around the vessel, monitored from the helm or interior monitors. A Dockmate wireless docking system assists with precision maneuvering during arrival and departure—particularly valuable for a 57-foot catamaran in tight marina or anchorage situations. The primary helm also includes a Ritchie compass, Hella navigation light suite (head, stern, port, starboard, and anchor), rudder indicators, engine console with full instrumentation, and a Jabsco remote control searchlight. A Roca wiper system with spray wash provides clear visibility in poor weather. The helm chair is an upgraded model, ergonomically designed for extended periods of operation. Navigation and docking are further supported by a SeaStar electrical hydraulic steering system compatible with autopilot operation, stainless steel emergency tillers, and fiberglass rudders with Aqua 17 high-tensile shafts. The CJR rudder shaft seal system protects the steering mechanism from saltwater intrusion.
Power and Propulsion
Twin Cummins 550 HP QSB6.7 diesel engines with approximately 260 hours of operation power the Granocean 57. These engines are paired with ZF280IV gearboxes and coupled to Hungshen four-blade bronze propellers via Aqua 17 high-tensile direct transmission shafts. The PSS engine shaft seal system prevents leakage around the propeller shafts, while the CJR rudder shaft seal protects the steering system. The engines achieve a maximum speed of 21 knots at full throttle, consuming approximately 36 gallons per hour. More practically, the vessel cruises efficiently at 10 knots, burning 14 gallons per hour for a range of 1,140 nautical miles on the 1,585-gallon fuel capacity. At 9 knots, fuel consumption drops to 9 gallons per hour, extending range to 1,600 nautical miles. At economical 8-knot cruising, the engines consume 6 gallons per hour, permitting a 2,100-nautical-mile range—sufficient for crossing the Caribbean or traversing the U.S. East Coast without refueling. The long-range fuel tank configuration (1,500 gallons / 5,800 liters) is integrated into the hull structure as FRP tanks with electrical gauges. Racor 500 series fuel filter/water separators protect each engine, while a Reverso fuel polishing system (owner-installed upgrade) maintains fuel cleanliness during extended storage or cruising. A diesel emergency shut-off valve and Jabsco fuel transfer pump between tanks provide redundancy and operational flexibility. Joystick control at the flybridge helm simplifies maneuvering, allowing single-handed operation of both engines and
