First look: On board "groundbreaking" 29m Sunreef 100 Eco sailing catamaran

6 November 2026 • Written by Lucy Pughe-Morgan

Following her world debut at this year's Monaco Yacht Show, Polish shipyard Sunreef Yachts has shared the interior images of the first unit from its "groundbreaking" Sunreef 100 Eco sailing catamaran series. 

The 29.3-metre new build hit the water at the shipyard's facilities in Gdańsk, Poland, in June and was delivered to her owner – a repeat Sunreef client – two months later as Ipharra II. The project's sale was first announced during the 2022 Fort Lauderdale International Boat Show, with construction commencing in early 2023, exclusive BOATPro data notes.

According to the yard, the build was born from her owner's growing interest in innovative onboard technologies that enhance the cruising experience without compromising on luxury, comfort or performance. 

New images reveal the yacht's interiors, developed by Sunreef's in-house design team in close collaboration with the owner, which combine "architectural levels of craftsmanship" with generous volumes to "create an atmosphere of serenity and effortless comfort", according to the yard. This philosophy is reflected across the yacht's living areas, including in the main saloon, which features light wood paired with a neutral colour palette. 

The open-plan space offers deep sofas in light upholstery, a dark-stained ten-person dining table and a coffee bar. Smart design touches, including a retractable projector screen concealed within the headlining, add another layer of "effortless comfort" to the saloon. The builder also noted the interior's use of "responsibly sourced or recycled finishing materials".

The main saloon spans the 12.8-metre beam

Designed for extended periods at sea, the yacht combines generous living areas with accommodation for up to 12 guests alongside a spa, gym, bar and office. A large, full-beam owner's suite is located forward, with glass privacy panels separating the sleeping area from the bathroom and shower. A passageway to the foredeck of the yacht is deliberately narrow and can be closed off at the request of the owner to ensure complete privacy. 

Five additional guest cabins can be found on board, including a single cabin adjacent to the owner's suite and four en suite guest cabins in the hulls, which can be configured as either doubles or twins.

The layout of the outdoor areas also supports extended cruising periods, including an expansive main deck aft, a sheltered cockpit dining area and a large flybridge for al fresco entertaining. 

A highlight of her exterior is the large Ocean Lounge to the yacht's aft, which has been "ingeniously redefined" with an invisible garage for two jet skis, water toys and a dive locker nearby. Here, twin fold-down bulwarks and an expansive aft platform open the area into a "seaside terrace" for sunbathing, socialising, watersports and more.

The model can be fitted with a spa pool on the flybridge, but the owner of hull one chose to forego this option

Where technical details are concerned, the yard describes the catamaran as a "major step forward in sustainable yachting", with the all-electric model featuring twin 360kWh electric engines, a 770kWh battery bank and Sunreef’s proprietary solar power system, which sees solar panels integrated into the hull, superstructure and bimini for continuous clean energy generation. 

According to the yard, the solar panels alone generate up to 49kWp of clean energy to cover all hotel loads on board. Meanwhile, her carbon mast supports a sail plan capable of delivering speeds of 15 to 20 knots (in optimal winds), with cruising speeds of 8 to 10 knots.

The catamaran was launched in June

“With the Sunreef 100 Eco, we are proving that the future of superyachting can be both luxurious and responsible,” Francis Lapp, founder and president of Sunreef Yachts, said at the yacht's launch in June. “Combining electric propulsion, solar power and the efficiency of sailing, this yacht sets a new benchmark for clean cruising.” 

According to BOATPro, the shipyard has 23 yachts currently on order or under development, including a new 26.8-metre Ultima 88 catamaran for Argentine footballer Lionel Messi. The Sunreef CEO sat down with BOATPro in March this year to discuss the yard's ambitious new growth target.
