COR780

The COR780 is built with solid, high-quality construction to ensure maximum safety for all onboard, especially children. The high bulwarks, nearly 1 meter (3.2 feet) tall, provide excellent protection, and lifebuoys are strategically placed for quick access on the main deck and flybridge, with additional space for a life raft.

Advanced Bilge Water System

The COR780 is equipped with top-tier bilge water pumps across three sections. Each section includes a standard 32L/min (8.48 GPM) pump and a high-water-level pump with a 200L/min (52.8 GPM) capacity. Additionally, a hand pump allows for manual water removal at 100L/min (26.4 GPM). For Long Range Cruisers, a mechanical pump driven by the main engine offers extra protection. The hull’s sandwich structure ensures that even in the event of a collision, water is effectively pumped out.

EMPIRBUS Safety and Diagnostics

The COR780 features the EMPIRBUS diagnostic and alarm system, providing real-time warnings of any potential dangers. Backup batteries near the wheelhouse ensure communication and navigation systems stay operational for hours in emergencies, including navigation lighting.

Comprehensive Communication and Navigation

Standard safety features include:

• Two independent VHF radios and GPS receivers
• Radar, foghorn, and AIS Class B transponder
• Option for IRIDIUM satellite communicator for rapid emergency communication
• For Long Range Cruisers (LRC), an AIS Class A transponder is available

Reliable Twin Drive System

The twin drive system offers superior performance compared to a single engine, with an additional get-home engine for added safety. LRC configurations include redundant steering, fuel, electric, and water systems for total reliability on long voyages.

Fire Safety

The COR780 is equipped with two SEA FIRE automatic fire extinguishing systems, one in the engine room and the other in the bow engine room, providing thorough fire protection. 

Thanks to the expertise of Structeam UK, our yachts are designed with precision and efficiency. The structure incorporates an intelligent balance of reinforcements and lighter sections where loads are minimal. This advanced method replaces traditional, unnecessarily heavy designs with sophisticated materials and vacuum infusion lamination. Reducing weight is key to improving fuel efficiency, making our yachts not only high-performance but also eco-friendly.

Construction Parameters:

• Type: GRP (Glass Reinforced Plastic) - All parts are manufactured using Vacuum Infusion Technology.
• Primary Materials:
  • DIPEX/SAERTEX multiaxial fiberglass
  • Resins and gelcoats from BUFA, Ashland, Scott Bader, or better
  • Polyester or vinyl ester resin (for vacuum-infused parts upon request)

Hull Design:

• Core Structure: Features a laminate with foam core (Divinycell/Mycell 25mm-35mm H100/H130/H200), with the keel, bow, chine, and shaft housing made of solid laminate up to 19,800g per square meters.
• Infusion Process: The hull is laminated using vacuum infusion technology with vinyl ester resin and SoricTF for critical areas.
• Custom Solid Laminate Option: For those preferring fully solid laminate construction, this option is available.

Reinforcements:

• Stringers: Six full-length girders on the hull bottom and two additional stringers on each side, with solid laminate manufactured via infusion on structural foam.
• Bulkheads: Infusion composite with Divinycell/ Mycell CORE foam H80 (30mm-35mm) and multiaxial fiberglass up to 8,800g per square meters.
• Main Deck: Composite with Divinycell/ Mycell CORE foam H80 (20mm-25mm) and fiberglass up to 16,200g per square meters.

Connections and Finishing:

• Deck/Hull Connection: Bonded with structural adhesive (Crestomer 1152PA) and laminated with multiaxial fiberglass tapes.
• Superstructure and Hardtop: Sandwich infusion composite with Divinycell/ Mycell CORE foam H80/H200 (20mm-35mm).
• Engine Foundations: Made of solid laminate with metal washer plates for a secure foundation.

Windows:

• Hull Windows: Portholes are made from acrylic glass (10-12mm thick), while larger side windows range from 12-16mm. Steel storm covers can be added to smaller hull windows for added protection.

Finishing Laminate:

• Standard Finish: The hull and superstructure are coated with white gelcoat.
• Custom Options: Customers may opt for a polished finish with single-layer varnish or tri-coat pearl/metallic upon request.

Our hulls are designed exclusively for us by renowned engineer Grzegorz Władziński, combining advanced features to meet the highest demands for performance, stability, and comfort.

Sharp Bow & Spacious Interior: The hull features a sharp bow at the waterline and a wide, squat design where interior space is needed, maximizing usability. The near-vertical bow creates additional room between the bow edge and collision bulkhead, providing more functional interior space.

High Bow for Reduced Spray: With a height of over 3m (10ft) above the waterline, the bow minimizes foredeck soaking, ensuring a dry and comfortable experience in rough conditions.

Efficient Speed Range: The hull is optimized for reduced resistance at cruising speeds of 7-10 knots, ensuring smooth and economical sailing.

Flattened Stern for Stability and Speed: The wide, flattened stern allows for increased speed when necessary, such as avoiding poor weather or reaching an anchorage before dark. It also reduces side-to-side swaying, offering a more stable ride.

Optimized Weight Distribution: All critical weights, including the engines, are positioned as low as possible to lower the center of gravity and enhance comfort by reducing rolling.

Optional Keel for Enhanced Stability: An optional keel can be added to improve buoyancy, lower the center of gravity, and strengthen the righting arm, significantly improving stability and protecting rudders and screws during shallow water navigation.

Innovative Bow Design: Our cutting bow pear, unlike a typical bulbous bow, slices through the water efficiently to minimize energy loss and reduce drag. This unique shape also improves comfort when navigating choppy waters.

Advanced Stabilization & Thruster Design: Optional active fins are available for added stabilization. Additionally, our bow thruster tunnels are CFD-tested to prevent undesirable vortices and resistance, ensuring maximum efficiency.

Underwater Exhaust & Deck Drainage: Like our thrusters, underwater exhaust exits are CFD-tested for optimal performance. Storm drains, equipped with reverse-blocking functionality, ensure effective deck drainage even in severe weather.

Each of these features is meticulously engineered and tested, guaranteeing an unmatched experience on the water, no matter the conditions.

The COR780 features a hard-wired automation system with simple, intuitive controls. Each system can be activated by pressing a button, making it user-friendly and easily serviceable. Most devices are connected with standard contactors, ensuring repairs can be carried out by virtually any mechanic.

For more advanced monitoring, the Empirbus Automation System is installed. This top-tier European electronic system oversees all yacht systems, displaying data on its screen or an MFD page. The system monitors tank levels and can be expanded based on additional equipment and customer preferences.

Switchboards

The COR780 is equipped with three main switchboards:

1. Engine Room: Controls inverters, chargers, and edge socket protections.
2. Pilot House: Manages power source selection, battery banks, bilge pumps, and redundant systems.
3. Settings: Rotary switches provide intuitive controls for power systems, ensuring easy operation even in high-stress situations.
