2026 Sunreef Ultima 66

The Sunreef Ultima 66 combines monohull and catamaran design principles in a single composite hull. Its narrow beam relative to length allows for horizontal surfaces connecting the twin hulls, creating an interior volume and layout closer to a traditional monohull than a conventional catamaran. The design reduces draft while minimizing water resistance, supporting both performance and efficiency.

The yacht accommodates six cabins and eleven heads across its full-beam layout. The owner's cabin spans the full width of the boat, and the design creates generous internal volume throughout. Folding bulwark platforms extend from the hull to form a private Ocean Lounge, opening the deck to the surrounding water.

Powered by a single diesel engine, the Ultima 66 measures 72 feet in length with a 24-foot beam. The composite construction and streamlined hull form define a yacht built for both comfort and responsible operation across extended cruising.
