Architectural Integrity & Craftsmanship

S/Y SUNREEF 80 ECO is the world's most advanced eco-responsible luxury sailing multihull, representing the future of sustainable yacht ownership. Delivered brand new in 2024 and registered EU VAT Paid, she integrates Sunreef's proprietary solar skin—producing up to 36 kWp from solar cells seamlessly integrated into the composite hull sides, superstructure, and carbon bimini. Her twin 180 kW electric propulsion motors are powered by an ultralight 160 kWh lithium-ion battery bank, granting silent, zero-emissions overnight anchoring without running generators. Massive 11.5-meter beam yields 340 sqm of interior and exterior deck spaces matching 45-meter monohulls.
