Three hundred and eighty-seven square metres of living space. That is a larger interior than Sunreef publishes for its eighty-foot sailing catamaran — delivered on a hull two metres narrower than the 80 Sunreef Power.
That single comparison is the clearest illustration of what the ULTIMA range is engineered to do.
Superyacht Volume, Ordinary Berth
The Sunreef ULTIMA 88 is 28.40 m (93 ft 2 in) overall on a 9.30 m (30 ft 6 in) beam, with 387 m² of living space and 6,000 l of fuel. The classic version runs Volvo Penta D13 engines with IPS 1050 pod drives — the largest package in the range.
Nine point three metres of beam on a ninety-three-foot yacht is narrow for a catamaran. It is what lets this boat take a berth that a 12-metre-wide power catamaran of similar length simply cannot, at the same nightly rate.
Check the Length Against Your Berth
The 88 measures 28.40 m, which is 93 ft 2 in — not 88 feet. As with the ULTIMA 66, the model numbers in this range are not lengths in feet.
If you are booking a berth or comparing against a monohull, use the published dimension.
Who It's For
This is a professional-crew yacht and the flagship of the narrow-beam range. Buy it if the 387 m² living-space figure is what you are buying, and you want superyacht volume without a superyacht berth.
The IPS 1050 package is the most capable in the ULTIMA range, and Sunreef gives battery output for the hybrid version as 22 kW to 75 kW alongside a hydrofoil option.
Design and Layout
Three hundred and eighty-seven square metres is the largest interior figure Sunreef publishes for any model in its range, and it sits inside 9.30 m of beam.
The range's standard equipment carries over: folding bulwark platforms that widen the aft deck at anchor, custom sea-stairs, dedicated water-toy stowage, and ultralight flexible solar panels integrated across the surfaces.
Every hull is drawn to its owner's brief, so the cabin, head and guest count are set in the contract.
Settle These at Contract
Request water capacity and draft in writing before contract, alongside displacement and performance. On a range whose entire premise is shallow draft, the draft figure decides where you can take the boat; on a 28-metre yacht the water capacity decides how long you can stay in one place once you get there.
Record observed speed and consumption at your intended rpm at sea trial, and if a broker or a listing hands you a precise Sunreef figure, ask which document it came from.
Where to Start
The ULTIMA 88 is superyacht volume on a monohull's berth footprint, which is a genuinely unusual combination at 93 feet.
Step across to the 100 Sunreef Power if full beam and a beach club matter more than marina access — it is four metres wider and files under a different range. Step down to the 77 or 66 if the size is more than you need.
