Sunreef 66 Ultima luxury cruising catamaran revealed

Featuring a 7.25-metre beam, the design-driven Sunreef 66 Ultima is quite narrow for a catamaran, giving it monohull-like levels of performance compared with traditional powered catamaran designs.

The fully composite design also adopts folding bulwarks aft, creating a huge rear cockpit that Sunreef calls the Ocean Lounge.

“In essence, the Sunreef 66 Ultima harmoniously merges the best attributes of monohull and multihull living spaces, coupled with a shallow draft that challenges traditional norms in luxury yachting,” Sunreef said in a release announcing the new model.

“This vessel introduces a new paradigm in marine architecture, rewriting the rules of opulence on the open seas.

“Sporting a sleek and sporty hull, it ensures effortless access to any marina, while its advanced design minimises drag for heightened performance and energy efficiency. 

“The Sunreef 66 Ultima pioneers a distinct category, outclassing competitors with its combination of speed, comfort, and sustainability – no fumes, no vibration, no trace.”

That last statement points to the fact that this catamaran will be available as either a “Classic” version featuring twin 380hp engines with the option to increase performance to 480hp or as an “Eco” diesel-electric hybrid version featuring a propulsion system that is yet to be announced.

However, owners of this boat can expect a catamaran like no other out there on the water.

Of note, it features a beam-to-length ratio that Sunreef claims is more reminiscent of a monohull boat than a twin-hull design.

This allows Sunreef to build the three-level 66 Ultima with a huge freeboard that greatly increases the amount of interior space, including a full-beam owner’s stateroom.

Sunreef launched the Ultima range of hybrid catamarans in March last year, initially offering just four models – a 44, 55, 77 and the flagship 88.

The new range’s focus is on giving owners the ability to enjoy the water, with an emphasis on ease of access and enough storage space for an array of water toys.

The smaller 13.7-metre 44 features two staterooms, each with its own ensuite, while the 26.8-metre 88 features up to four guest suites including a full-beam master stateroom forward.

The flagship model includes a hydrofoil option to reduce the hulls’ wetted surfaces and increase fuel efficiency even more.

No mention was made of the the new model would make its real-world debut.
