Hull infusion on the Sunreef 43M Eco

Sunreef Yachts has announced the successful completion of the 43M Eco’s composite hull infusion process (click for video), which it described as “the biggest single-shot hull infusion project in yachting history”.

Francis Lapp, Sunreef’s founder and President, said: “We achieved an important milestone on our journey to build a truly groundbreaking yacht. The scale of the hull-infusion project is unique in the industry, and underscores our pioneering role in shaping the future of energy-efficient yachting.”

Under construction at the builder’s main shipyard in Gdansk on Poland’s north coast, the Sunreef 43M Eco is set to become the world’s largest electric catamaran. The biggest model to date in the builder’s Eco series, the 43m-long hull has a 15.4m beam and 1,700sqm of composite surface area.

The yacht’s innovative design features a custom-engineered foam core that reduces weight while improving performance. Infusion produces a stronger, lighter hull due to more even distribution of resin, which is sucked into the fibreglass and coring using vacuum pressure. The unmoulding of the hull is scheduled for completion by the end of this year.

Designed to accommodate up to 12 guests, the hull will incorporate over 120sqm of integrated solar panels, almost half of the total of 250sqm across the entire yacht.

The advanced solar technology and electric propulsion are among the superyacht’s emission-free, energy-saving features, with Sunreef stating that the 43M Eco “will redefine the superyacht experience, making it cleaner, more responsible, and energy-efficient”.

A hydrogeneration system will provide a steady supply of clean power while under sail, helping ensure an emission-free cruising experience. The energy-storage system will be based on solid-state batteries providing a capacity of 1MWh.
