The largest ULTIMA model below 24 metres
At 23.5 metres, the Sunreef ULTIMA 77 brings the ULTIMA philosophy close to the top of the sub-24-metre luxury-yacht sector. It combines the range's low, streamlined profile with the broad living platform of a power catamaran, giving owners a different proposition from a conventional sports yacht or flybridge motor yacht. The additional length also allows the ULTIMA concept to move beyond weekend use toward more substantial cruising and accommodation.
Performance-led multihull design
Sunreef developed the ULTIMA family around the idea of combining multihull stability and usable beam with faster, more dynamic cruising. Folding platforms and flexible exterior zones expand the waterside living area when the yacht is at anchor, while the low-profile architecture keeps the visual emphasis on speed rather than traditional high-volume catamaran styling. Larger ULTIMA models also offer greater freedom in cabin arrangement, galley provision and upper-deck configuration.
Customisation remains central
The range is offered with multiple propulsion approaches, including conventional and hybrid-oriented packages, alongside Sunreef's broader solar and battery technology. Because layouts and systems can be tailored extensively, a buyer should treat published model information as the framework for a build rather than a fixed specification. On a yacht of this size, crew arrangement, tender and toy storage, energy capacity, cruising range and owner-space priorities can materially change the final configuration.
