 (GdaÅ„sk, Poland), a designer and manufacturer of luxury sailing and power multihulls, is constructing what it says is the world’s largest eco-electric catamaran. The boatbuilder recently completed the composite hull infusion process for its Sunreef 43M Eco vessel, marking it as “the biggest single-shot hull infusion project in the yachting industry.”

The Sunreef 43M Eco hull measures 43 meters in length and 15.4 meters in width, encompassing a total composite surface area of 1,700 square meters. Its design features a custom-engineered foam core that minimizes weight while maximizing performance. The unmolding of the hull is scheduled for completion by the end of 2024.

According to the company, the hull will also incorporate more than 120 square meters of integrated solar panels, contributing to a total of 250 square meters across the entire yacht. The solar technology, combined with electric propulsion, aims to redefine the superyacht class’ environmental cleanliness and energy efficiency.

In addition to its “avant-gardist” solar technology, the Sunreef 43M Eco will be equipped with a hydrogeneration system to enable a steady supply of clean power while under sail, ensuring an emissions-free cruising experience. The yacht’s energy storage system will be based on solid-state batteries providing a capacity of 1 megawatt-hour.

The Sunreef 43M Eco is designed to accommodate up to 12 guests, offering luxurious living spaces and customizable features that cater to individual preferences.
