Monte Carlo, Monaco — 23 September 2026 · world premiere at the Monaco Yacht Show.

The first Sunreef 100 Eco makes her world premiere at the Monaco Yacht Show, straight from outfitting and sea trials.

Her world premiere at Monaco

Sunreef says the first Sunreef 100 Eco goes from final outfitting and sea trials straight to her world premiere at the Monaco Yacht Show. The yard launched her in June 2026, describing her as the first of the class. She was commissioned by an owner who had already had a Sunreef superyacht built.

Electric, solar, and still a sailing boat

Solar panels are built into the hulls, the superstructure and the bimini, so the yacht makes its own power without anything showing on the outside. She carries a 770 kWh battery bank. Sunreef frames the combination — comfort, range and energy independence — as a step forward in sustainable yachting.

Silent, fumeless, ocean-crossing

The yard calls the Sunreef 100 a visionary sailing catamaran built to cruise with no emissions and in complete silence. Electric motors and custom battery banks give long hours of clean, vibration-free running. Under sail, hydro-generators turn the boat's own motion back into power.

The Ocean Lounge

The signature feature is the Ocean Lounge, which Sunreef traces to its NEXT design language. It joins a wide aft platform to fold-down bulwark balconies, opening the space out into a terrace at the waterline. The aft section also hides a garage big enough for two jet skis and a spread of water toys.

Sunreef at Port Hercules

Sunreef takes two flagship models to Monaco, which runs from the 23rd to the 26th of September at Port Hercules. The yard describes them as two of the shipyard's flagship models. They lie at berth QH25.

“With the Sunreef 100 Eco, we are proving that the future of superyachting can be both luxurious and responsible”
