Two Sunreef 100 Eco yachts recently commissioned will feature composite integrated solar panels and other advanced green technologies.
The shipyard has been tasked with building two Sunreef 100 Eco superyachts, both sailing catamarans ordered by repeat customers.
One of the vessels is scheduled for delivery to Europe in late 2025, with the other to the Americas in 2026.
The Polish shipyard is leading a sustainable revolution in the superyacht industry, with growing global interest in large, eco-responsible catamarans.
The Sunreef 100 Eco was designed to provide an emissions-free cruising experience in complete silence and luxury.
Utilizing high-tech green solutions developed in-house, the yachts will feature composite integrated solar panels, maximizing solar power generation.
With custom-engineered batteries and state-of-the-art electric engines, the Sunreef 100 Eco offers hours of e-motoring without fumes or vibrations.
The hydro-generators provide a steady supply of green energy, enabling a 2,000-nautical-mile range.
Expandable Ocean Lounge
A standout feature of the yacht is its invisible aft garage, capable of storing a jet ski and a collection of water toys.
Another highlight is the expansive Ocean Lounge, which combines the aft platform and fold-down balconies.
Dedicated to sunbathing, lounging, and watersports, this area provides direct access to toy storage and diving gear.
Blending cutting-edge green technology with impressive living space, the Sunreef 100 Eco represents the pinnacle of sustainable superyacht design.
This bespoke all-electric luxury craft joins the shipyard’s Eco range, which includes the 50 Eco, 60 Eco, 70 Eco, and 80 Eco.
Equipped with twin 270kW electric engines, the Sunreef 100 Eco delivers a sustainable yachting experience with ultralight, high-performance batteries and a proprietary solar power system.
This innovative craft can host up to 242.5sqm of composite-integrated solar panels, generating up to 46kWp of power.
Hybrid Propulsion and Wind Power
Hybrid engines not only offer reliable propulsion but can also recharge the yacht’s battery bank for enhanced energy efficiency.
Harnessing wind as an essential source of propulsion reflects a natural approach to yachting.
The sailing range of electric catamarans includes top-quality rigging and fully recyclable performance sails.
Wind also serves as a valuable support for motoryacht propulsion.
The eco-friendly power yacht range can be fitted with high-performance kites, a solution frequently employed to tow large container ships. These kites provide a powerful supplemental propulsion system for leisure craft.
Hull Optimization
Under electric motor propulsion, all Sunreef yachts demonstrate exceptional energy efficiency due to advanced hull designs refined through computer simulations.
Adjustments to hydrodynamics and aerodynamics are tailored to optimize energy use, seaworthiness, and performance across various sea conditions.
The Eco Ethos
Following the shipyard’s Eco philosophy, the Sunreef 100 Eco integrates responsibly sourced or recycled finishing materials along with an ultramodern, energy-saving air-conditioning system.
These catamarans embody a 360-degree approach to eco-responsible cruising, combining cutting-edge propulsion solutions, naturally-sourced materials, smart energy management, and proprietary solar power systems.
The design includes wind generators, non-toxic bottom paints, green composite structures, and advanced watermakers.
Optional hybrid propulsion systems further enhance eco cruising by reducing CO2 emissions and merging electric motoring with thermal engines for greater efficiency.
Weight Efficiency
Weight optimization is key to energy-efficient yachts. The Eco range incorporates lightweight carbon fiber in masts, booms, and structural reinforcements, reducing overall weight while boosting energy performance.
Lithium battery banks are strategically placed to minimize their impact on the yacht’s movement, and the solar panels used are among the world’s lightest.
Energy and Water Management
To minimize energy consumption on board, the yachts feature well-insulated interiors constructed from sustainable materials.
These spaces maintain stable temperatures, while the battery-powered air-conditioning system operates silently. Smart energy management allows for reduced generator usage, ensuring all systems function efficiently.
The Eco range also includes efficient watermakers and purification systems, providing unlimited access to fresh water and reducing reliance on plastic bottles.
Rain collection systems and solar-powered or inverter-heated boilers add further water efficiency.
Sustainable Materials
The Eco range employs basalt and linen-based components in hulls, superstructures, and furniture.
Basalt, a volcanic rock, offers superior strength compared to glass fiber and is safer for the environment during production.
Linen fiber, derived from flax, is another eco-friendly material with a minimal carbon footprint.
Luxury finishes avoid animal skins, instead offering natural fabrics and alternatives to genuine leather.
Reclaimed teak from old buildings or boats can be used for flooring, while countertops may feature compressed paper-based materials for durable, lightweight surfaces.
Cork-based and recyclable synthetic teak options are available for decking.
Non-toxic, silicon-based hull-bottom paints protect against marine growth while reducing drag, improving performance and energy efficiency.
Recycled sailcloth from the Eco range is repurposed into durable bags and accessories, extending its lifecycle.
Pioneering Sustainable Yachting
The Sunreef 100 Eco exemplifies the shipyard’s commitment to sustainable yachting by combining massive living space with cutting-edge green technology and smooth sailing.
With a growing interest in eco-conscious cruising, these yachts are gaining attention worldwide for their innovative design and environmental responsibility.
