Catamaran motor yacht 55 ULTIMA ECO

charterhard-tophybrid

Description
The SUNREEF 55 ULTIMA ECO is a 17 m hybrid catamaran engineered to minimize energy consumption while maintaining stable, quiet performance. Combining electric propulsion, efficient hull geometry and integrated solar panels, it offers a low-consumption platform suitable for private ownership and charter operations.

Design & living
The layout prioritizes open living and easy movement on board. A full walkaround deck improves safety and circulation, while the large semi-open saloon connects directly to generous aft lounging areas. Twin fold-down bulwark platforms increase usable beam at anchor and convert the stern into an accessible waterside area. Custom sea-stairs and dedicated storage spaces keep water toys and boarding gear organized and ready.

Energy & systems
Ultralight, thin and flexible solar panels are integrated discreetly into the structure to support onboard systems and reduce generator dependence. Configurations include electric propulsion (2 x 350 kW) and optional diesel (2 x 600 hp), providing a balance between silent electric cruising and extended-range diesel operation.

Use case
Designed for private cruising and high-end charter, the platform combines progressive eco-innovation with practical onboard ergonomics and comfort.
