You want 387 square metres of living space on a hull just 9.3 metres wide. The ULTIMA 88 is the largest boat in Sunreef's narrow-beam range and the one that carries the most volume per metre of berth.
Part of the Sunreef ULTIMA series — see how owners step up through the lineup.
Quick Verdict
- 387 m² of living space inside 9.30 m of beam — a larger published interior than Sunreef's 80-foot sailing catamaran, on a hull more than two metres narrower than the 80 Power
- Volvo Penta D13 with IPS 1050 pods, the largest drivetrain in the ULTIMA range, with hybrid battery output given as 22 kW to 75 kW
- 28.40 m overall, or 93 ft 2 in — the model number is not the length, and neither water capacity nor draft is published
Our Take
Three hundred and eighty-seven square metres of living space is a larger number than Sunreef publishes for the 80 Sail NEXT sailing catamaran, and the 88 does it on a hull three metres narrower than the 80 Power. That is the ULTIMA argument at its strongest: superyacht volume that will still take a conventional berth.
The drivetrain is the biggest in the range — Volvo Penta D13 with IPS 1050 — and the boat carries six thousand litres of fuel. What Sunreef does not publish is water capacity or draft, which on a boat this size is a genuine gap. Ask.
The 88 is also the model where I would double-check the length against your berth. Twenty-eight point four metres is ninety-three feet, not eighty-eight. The ULTIMA numbers are not feet.

Sunreef ULTIMA 88 Overview
The Sunreef ULTIMA 88 is the largest boat in the yard's narrow-beam performance range. Sunreef publishes 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.
That living-space figure is larger than the one Sunreef publishes for the 80 Sail NEXT sailing catamaran, on a hull more than two metres narrower — the clearest illustration of what the ULTIMA range is engineered to do.
The classic version runs Volvo Penta D13 with IPS 1050 pods. Battery capacity for the hybrid version is given as 22 kW to 75 kW. As across the range, the ULTIMA model number is not the length in feet.
Performance & Handling
Sunreef publishes no speed or cruise figure for the ULTIMA 88, so those rows are empty.
The classic drivetrain is Volvo Penta D13 with IPS 1050 pod drives, the largest package in the ULTIMA range. Sunreef gives battery output for the hybrid version as 22 kW to 75 kW, alongside a hydrofoil option and ultralight flexible solar panels.
Fuel capacity is 6,000 l. Neither water capacity nor draft is published for the 88 — both worth requesting in writing on a yacht of this size.
Interior & Accommodations
Three hundred and eighty-seven square metres of living space is the largest figure Sunreef publishes for any of the fourteen models we cover, and it sits on a hull just 9.30 m wide.
The range's standard equipment carries over: folding bulwark platforms that widen the aft deck at anchor, custom sea-stairs, and dedicated water-toy stowage. Solar panels are ultralight flexible units integrated across the surfaces.
Sunreef publishes no cabin or head count and no guest number for the 88. Every hull is drawn to its owner's brief.
Market Position
The ULTIMA 88 is a superyacht-scale catamaran with a monohull's berth footprint, which is a genuinely unusual combination at 93 feet. Its nearest in-house comparison is the 100 Sunreef Power, which is four metres wider and files under a different range.
Against monohull motor yachts of similar length it offers far more deck area and much greater stability at anchor, on a berth that costs the same.
This is the top of the ULTIMA range and, in living space, the largest interior Sunreef publishes anywhere below its bespoke superyacht projects.
Who the ULTIMA 88 Is For
Buy the ULTIMA 88 if you want superyacht volume without a superyacht berth, and the 387 m² living-space figure is what you are buying. The IPS 1050 package is the most capable in the range.
Step across to the 100 Sunreef Power if full beam and a beach club matter more than marina access. Step down to the 77 or 66 if the size is more than you need. Request water capacity and draft in writing before contract — Sunreef publishes neither for this model.
