The turning point in the Ultima line
The 66 is the model where the Ultima range shifts from sporty day boat to serious cruiser, and it is the point at which flybridge and galley layouts open up. It carries the low-drag performance hull of the smaller Ultimas at a size that can host eight guests plus three crew. That makes it a genuine holiday yacht with the manners of a sportscat. It sits between the 55 and the 77 in the line. For an owner who found the smaller Ultimas too focused on day use, the 66 is the balance point.
Sunreef builds the 66 in an Eco form with electric propulsion and solar and in a classic form with Volvo D8-IPS 800 engines. The Eco version brings silent anchoring and emission-free short runs. Fuel tankage of two thousand litres per tank on the classic gives it real touring range. An owner chooses the balance of speed and silence. That range is what lifts the 66 from a coastal toy to a boat for a proper cruising itinerary.
Design and deck life
At 22 metres with a 7.25-metre beam, the 66 has the deck space for a full flybridge and generous social areas. A vast aft platform and fold-out bulwark terraces create an Ocean Lounge that brings guests down to the water. The forward deck adds a private sun lounge away from the helm. Owners tailor the shade, dining and sunpads to their own use. The Ocean Lounge is the party piece, opening the aft deck into a wide terrace at the waterline.
The styling keeps the athletic Ultima stance while carrying the extra volume with grace. Custom paint and detailing personalise the exterior. The flybridge gives a second helm and a commanding social deck up top. This is a boat built to entertain as well as to move quickly. The flybridge doubles as the social heart of the yacht once the anchor is down.
Where the sportscat becomes a cruiser: flybridge, full-beam owner's suite, Ultima pace
Interior and accommodation
Inside, the 66 offers an exceptionally spacious full-beam owner's cabin, a highlight of the layout. The four deck arrangements let an owner set the cabin count and the flow of the interior. Sunreef finishes every surface to its bespoke standard in the owner's chosen materials. Water capacity of eight hundred litres supports comfortable stays for the guest party. The full-beam master gives the owner a suite closer in scale to a land bedroom than a boat cabin.
The galley can be placed to suit crewed service or a hands-on owner. Large glazing keeps the saloon light and connected to the sea. Storage and systems are scaled for extended cruising. The interior feels like a refined apartment carried on a fast hull. The four layout options mean two 66s can be configured for very different lives, from family holidays to crewed charter.
Engineering and performance
The 66 keeps the lower-drag Ultima hull that gives the range its pace and efficiency. The classic version uses Volvo D8-IPS 800 pod drives for strong performance and precise handling. The Eco version swaps to electric propulsion and solar for silent, clean running. Pod drives make the 66 easy to manoeuvre for its size. The efficient hull means the 66 covers ground quickly without the fuel appetite of a heavier cruiser.
The composite structure is built in house for stiffness and controlled weight. The performance hull means the 66 cruises quickly without heavy fuel burn on the classic engines. Systems are engineered for autonomy away from a marina. The result is a cruiser that still feels quick and alive underfoot. Owners stepping up from a sports boat will recognise the sharp response despite the extra size.
The owner it suits
The 66 Ultima suits an owner who wants Ultima performance with the space to cruise for real weeks. It rewards those who host eight guests and want a flybridge and a full owner's suite. Buyers who find the smaller Ultimas too focused on day use will find the balance here. It carries a small crew comfortably. It fits the owner who wants speed and a genuine holiday yacht in the same hull.
It also makes a strong charter yacht for guests who want speed and style together. The Ocean Lounge and flybridge give it genuine host appeal. For an owner stepping up from a sports day boat, the 66 adds cruising range without losing the character. Life aboard is quick, social and comfortable. The charter appeal gives an owner a clear route to offset running costs between private trips.
Who it is for: Owners who want Ultima performance with a flybridge, a full owner's suite and true multi-week cruising range.
