Sunreef ULTIMA 66 overview
The Sunreef ULTIMA 66 is a 22.00-metre power catamaran designed to blur the traditional distinction between multihull volume and monohull proportions. Its 7.25-metre beam is wide enough to create a substantial full-beam living environment but noticeably narrower, relative to length, than many conventional cruising catamarans. Sunreef uses that proportion to reduce drag and improve marina practicality while retaining the benefits of twin hulls.
Folding bulwark platforms expand the aft deck into a broad waterside lounge. Inside, the connected volume between the hulls allows a large owner's area and substantial social spaces. The design therefore targets owners who want a large waterside lifestyle platform without moving to the 10-metre-plus beam common among some 70-foot luxury catamarans.
Dimensions, capacities and engines
The official specification gives a 22.00-metre overall length, 7.25-metre beam and 1.20-metre draft, with composite construction. The classic version is listed with Volvo D8 IPS 800 propulsion. Fuel capacity is 4,000 litres in two 2,000-litre tanks and fresh water capacity is 800 litres.
Sunreef publishes accommodation for eight guests plus three crew. That crew provision is significant within the Luxury Yacht Guide size band because it supports a more formal operating model than is common on smaller production yachts while remaining below 24 metres overall.
Hybrid and coastal-cruising potential
The ULTIMA line is also promoted with hybrid and electric technology options. Exact energy-storage and propulsion packages can differ by specification, so buyers should treat the builder's current project information as a starting point and verify the equipment fitted to a particular hull. The shallow 1.20-metre draft and IPS-powered classic arrangement make the platform particularly interesting for coastal cruising and low-speed manoeuvring.
Luxury Yacht Guide assessment
The ULTIMA 66 occupies a distinctive position around 22 metres: it offers considerably more beam and internal floor area than a monohull, yet avoids the extreme width of many traditional luxury catamarans. For owners balancing onboard space, crew accommodation, shallow-water access and berth practicality, it deserves comparison with both large power catamarans and high-volume 70-foot motor yachts.
