PROPULSION

The fleet utilizes a dual-engine configuration as a standard to ensure total mechanical redundancy; single-engine architectures with auxiliary get-home motors are rejected in favor of independent propulsion circuits. Engine room specifications feature high-output Volvo Penta or MAN marine diesels, integrated with ZF transmissions equipped with trolling valves for precise, low-speed maneuverability. Power transmission is achieved through a direct angular output design, minimizing mechanical complexity and ensuring global serviceability. Propulsion units are seated on high-rigidity structural stringers reinforced with 8mm stainless steel plating to eliminate vibration. In extended-range configurations, the architecture incorporates full systemic redundancy across fuel, electrical, and hydraulic subsystems.

02 // DETAIL

CONSTRUCTION

All units are engineered and manufactured utilizing the Vacuum Infusion Process (VIP) for optimal weight-to-strength ratios. The hull utilizes a sandwich composite structure featuring a high-density foam core to enhance buoyancy and thermal performance. Critical structural nodes including the keel, bow, chine, and shaft line housing, are fabricated from pure solid laminate, reaching grammages of up to 19,800 g/m² in extreme-load areas. The longitudinal framework, comprised of six full-length girders, is engineered to manage severe dynamic stress. This composite matrix ensures that the hull maintains structural integrity under oceanic conditions, with superstructure fenestration utilizing high-thickness, impact-resistant glass compliant with CE-A ocean certification standards.

SEAWORTHINESS

The hull geometry is optimized for transoceanic stability, featuring a high-volume, near-vertical bow profile that maximizes internal space and mitigates deck wash. Each hull incorporates a dedicated bulbous cutting bow engineered to optimize hydrodynamic flow and dampen pitch in head seas. The stern section is optimized for roll reduction, minimizing side-to-side swaying. The vessel’s center of gravity is maintained at the lowest possible point through deep-seated machinery and ballast placement. Bow thruster tunnels and underwater exhaust geometries are verified via Computational Fluid Dynamics (CFD) to eliminate drag-inducing vortices. Deck drainage is managed by high-capacity storm drains equipped with reverse-flow blockage, ensuring rapid water evacuation under heavy sea states.

NAVIGATION

The navigation and communication suite is based on a modular GARMIN architecture, scalable to full commercial FURUNO specifications. The baseline infrastructure includes dual independent GPS receivers, multifunctional displays, radar systems, and Class B AIS transponders. Extended configurations integrate commercial-grade equipment, including SSB MF/HF transceivers, open-array radar, Class A AIS, and satellite communication (Iridium) packages. Steering is managed by a heavy-duty hydraulic system featuring dual-cylinder actuation and variable-capacity pumps, with autonomous heading control provided by redundant autopilot processors. The yacht’s automation and telemetry are centralized via an integrated digital monitoring network (Empirbus).

Engineered for Stability

It is a very stable yacht. The wide hull effectively resists sideways swing. An orderable full-size keel can be ballasted to lower the center of gravity. These solutions are especially useful for LRC configurations. As in all our yachts, the COR 780 has a huge number of lockers, useful rooms, and pantries. In the engine room there is a place for a small workshop for ongoing maintenance. Additional bottom elements, such as an extended keel or a cutting bow, are made on request.

  • Architecture: Long Range Cruiser (LRC)
  • Primary Application: Extended autonomous cruising
  • Hull Type: Stable Displacement with Optional Ballasted Keel
