Structural materials

The yacht’s structure is meticulously engineered in advanced composites, with the hull bottom and sides built as a GRP sandwich around a PVC core of 80–100 kg/m3 density for exceptional stiffness and impact resistance. The main deck and deckhouse are likewise executed in GRP sandwich with a PVC core of 60 kg/m3, balancing strength and weight for an impressively quiet, solid ride. All hull laminates are specified in vinylester resin for superior osmotic protection, while all other laminates employ polyester isophthalic resin, combining resilience and longevity. Primary laminates are produced by infusion for optimal fiber-to-resin ratios, complemented by GRP stiffeners laminated on PVC formers via hand lay-up directly onto the shell laminates to lock in rigidity. A pristine white DSM gelcoat finishes the exterior to a yacht-grade sheen. Below, the lower deck’s structural cabin sole is a GRP sandwich, and both watertight and structural bulkheads are crafted in GRP/PVC sandwich with 80 kg/m3 cores, with partition bulkheads in marine plywood; all bulkheads are securely bonded to the shell by lamination. Autonomy and reliability are ensured by independent fuel, freshwater, and grey/black water tanks, all fabricated in robust aluminium 5052.

Engine room and marine systems

Power comes from two 440 HP Yanmar or Volvo engines driving through twin shaft-drive gearboxes to two duplex stainless-steel shafts running in a GRP sterntube, with steering by Sea Star hydraulic helm and directional authority enhanced by a single bow thruster. The running gear is completed by two 316L stainless-steel rudders and two Cu3 propellers with four fixed blades for dependable thrust. Systems are comprehensively specified, with an Onan 13.5 kW generator including muffler and gas–water separator, and a Climma CWS air-conditioning system delivering 65,000 BTU with inverter efficiency. The engine room is accessed via a hatch on the main deck and lined with Pyrotek Sorberbarrier insulation, while electrical bonding is assured by a 4 x 32 mm copper strip. Ventilation and safety are paramount, with two engine room air inlets fitted with moisture eliminators, two air blowers for forced ventilation, two automatic Seafire fire-suppression systems with heat sensor and alarm, four fire dampers with remote shut-off, and dedicated mufflers for the main engines and generator. Fuel management includes two engine fuel filters, a genset fuel filter, a fuel transfer pump, and Trident 365 fuel hose. Bilge management is robust, with eight bilge pumps throughout the boat and a high-water alarm. Domestic systems include one 60 lts/16 gal water heater, two freshwater pumps, three grey-water sump pumps with tank, a grey-water macerator pump, a black-water macerator pump, and two deck wash points located at the cockpit and bow. For situational awareness, two engine room cameras and one docking camera provide clear oversight of operations.

Electronics

Confidence at the helm is anchored by an integrated Raymarine suite: an autopilot with P70 control head, two Axiom Pro 16” multifunction displays—one on the flybridge and one at the main deck helm—plus a Raymarine i70, echo sounder, and GPS RS 130, all networked via the Raymarine backbone and supplied with the requisite cables. Situational awareness is amplified by AIS with antenna and VHF with antenna, while the Raymarine CP 100 fish-finder sensor paired with CPT 120 delivers precise subsurface insight. Overhead, a Raymarine Radar FLIR Quantum Q24C sharpens your picture of weather and traffic, and a chain counter provides precise anchoring control.

Electrical system

Silent autonomy flows from a 2600 W solar array with regulating and charging system, feeding bonded shipwide AC/DC infrastructure with a dedicated ground plate and dual-voltage 24 VDC and 220/110 VAC services. Starting power is assured by two 150 Ah AGM gel-type engine start batteries and one 150 Ah AGM gel-type generator start battery, while hotel loads are sustained by a 24 V 600 ah lithium house bank. Power conversion is entrusted to a Victron Multiplus 24/5000/120 inverter/charger and a Victron Orion 24/12-40 converter. Control and protection are premium throughout with Vimar switches, BEP circuit breakers and fuses, a main AC/DC distribution switchboard, Quick Spa interior/exterior LED lighting, and Hella Marine navigation and anchor lights. Shore connectivity is comprehensive with two 50 A Marinco shore power cords and Vimar 220 V/110 V sockets distributed throughout.

Exterior outfitting

Every exterior touchpoint is conceived for elegance and utility: an aft cockpit folding-edge table in teak sets the tone alongside a 24 V horn, a dash-controlled remote searchlight, and a Glomex TV antenna. Dockside readiness comes standard with fenders and mooring lines x 6, a primer coat and black antifouling, plus Propspeed applied to shafts and propellers. The hull features a structural keel, Lewmar flush Mitre size 1 portlights, and a stainless-steel cap rub-rail along the hull side. On deck, Lewmar Mitre flush hatches size 44 and a large windshield hatch on the main deck flood interiors with light. Ground tackle is confidence-inspiring with a vertical Quick windlass, 2000 W 24 V, operated from deck switches, stainless-steel 13” mooring cleats and two 15” stainless-steel bollards, and a Lewmar anchor (DTX 40kgs/88lbs) served by 60m/196ft x 10mm/3’8” short-link chain. Safe movement is assured by S/S 316L handrails and stainless-steel cockpit stern gates, while comfort is enriched by two hot/cold shower faucets at the port and starboard transom steps. A Swissway swim ladder with Carina railing, telescopic 3 +2, hides flush in the transom for a seamless profile. Forward, two stainless-steel bow pulpits with teak seats invite panoramic moments. All outdoor cushions are upholstered in Sunbrella fabric, and every GRP non-skid area is molded into the laminate. Overhead, a GRP hard-top with stainless-steel navigation mast crowns the profile, complementing synthetic teak in the cockpit, on the stairs, and across the boarding platform. Handling toys is effortless with a stainless-steel davit lifting system with electric winch (250kgs). Practical luxuries abound, from a cockpit cabinet with storage, a 37 L stainless-steel bin, and a stainless-steel electric grill beneath a protective hatch, to a solid teak cockpit dining table. As night falls, six Aqualuma underwater lights in blue or white transform the waterline into a luminous stage.

Interior outfitting

The helm on the main deck is an ergonomic command center, complete with full engine instrumentation, a windscreen wiper, and a double Besenzoni Dragonfly adjustable helm seat with fore-and-aft adjustment, supported by intuitive engine controls, clear displays, a tilt steering wheel, and a magnetic compass. Daily life unfolds with refined practicality: a side shelf doubling as an office desk, a Fusion entertainment system with two speakers in the saloon and cockpit, remote control, amplifier, and subwoofer, and an electric TV lift in the saloon suitable for a 50” screen (not standard). The galley is comprehensively equipped with a fridge–freezer, an induction cooktop hob beneath a hood, an oven–microwave combination, a Solid Surface countertop (LG HI-MACS), and a stainless-steel sink with hot/cold faucet, while the cockpit benefits from a drawer fridge for effortless service. Touchpoints throughout include S/S 316L interior handrails, BLUM drawer systems and cabinet hinges, timber-veneer furniture and decorative elements, and parquet-laminate flooring across the main deck galley and dinette, contrasted by teak flooring in all bathrooms. The atmosphere is elevated by ceiling and wall panels in synthetic leather, with sofas and seats upholstered in Ultraleather by Ultrafabrics. Social spaces are flexible and elegant, from a saloon coffee table with two ottomans to a dinette table with two stools and drawer storage beneath the dinette sofa; a liquor cabinet seamlessly integrates into the galley counter if Galley Option A is selected. Tactile luxury extends to dark leather accents at the main deck helm and above the TV cabinet, manual blinds on all hull windows, and electric blinds on main deck windows (excluding the sliding door to the cockpit). Nighttime comfort is ensured by memory-foam mattresses, while practical amenities include Planus electric toilets with macerator, ceramic washbasins, Kohler bathroom and shower fixtures, a combination washer/dryer, separate shower stalls with teak gratings in each bathroom, air extraction fans in all bathrooms, and carpet on the lower decks and in the forward saloon on the main deck.
