Flagship of the Ultima line

The 88 tops the Ultima range, the largest and most capable expression of the yard's performance philosophy. At 28.4 metres it delivers superyacht volume while holding the efficient, lower-drag hull that sets the Ultimas apart. It is the boat for an owner who wants the range's pace and character at the highest end. Everything below it in the line looks up to the 88. It is the Ultima for an owner ready for a full crewed superyacht that still drives with intent.

Sunreef builds the 88 with Volvo D13-IPS 1050 engines in the classic version and with an Eco hybrid using battery packs from 22 kW to 75 kW backed by solar. The Eco drive brings silent anchoring and clean short runs to a yacht of this size. Both versions share the same performance platform. The owner sets the balance of speed and silence. That choice lets a buyer aim the flagship at fast ocean passages or at quiet, green cruising.

Design and deck life

With a 9.3-metre beam over 28.4 metres of length, the 88 offers deck spaces on a superyacht scale. A full flybridge crowns the yacht with dining, sun and a second helm. The aft platform and fold-down terraces open a broad beach club at the waterline. Owners lay out the shade, sunpads and bars to host large parties or to keep quiet retreats. The beach club and flybridge together give the yacht two very different social decks for a large guest list.

The styling carries the athletic Ultima stance into a bigger, more imposing form. Custom paint and detailing give each 88 its own presence. The foredeck adds a further private lounge above the water. The exterior is engineered for entertaining and for long days in the open air. Even at flagship size the 88 keeps the lean, purposeful look that marks the range out from a boxy motor cat.

Interior and accommodation

Inside, the 88 offers the volume for a full superyacht layout with beautifully appointed guest cabins and a commanding owner's suite. The interior is finished to a bespoke brief in the owner's chosen materials. Large glazing keeps the saloon light and open to the sea. The main deck flows out to the aft cockpit for indoor-outdoor living. The owner's suite sits at the centre of the yacht as a private residence within the superyacht.

Systems, storage and tankage are scaled for extended cruising with a full guest party and crew. The galley and crew quarters support professional service at this size. Climate control is engineered to work within the Eco energy budget. The interior atmosphere is expansive, refined and calm. The layout separates owner, guest and crew flow, so the yacht stays private even with a full complement aboard.

Engineering and performance

The 88 rides the lower-drag Ultima hull that keeps even the flagship quick and efficient. The classic version uses Volvo D13-IPS 1050 pod drives for strong, controllable power. The Eco version turns to electric propulsion with battery packs from 22 kW to 75 kW and solar. Pod drives keep a yacht of this scale manageable close in. The efficient hull is what lets the 88 hold a fast cruise without the fuel burn of a heavier flagship.

Sunreef builds the composite structure in house for the stiffness a fast, large hull demands. The performance form lets the 88 cruise quickly without the fuel penalty of a heavier design on the classic engines. Systems are engineered for genuine autonomy far from a shipyard. The result is a flagship that still feels agile. That in-house build underpins both the pace and the long-range comfort at this size.

The owner it suits

The 88 Ultima suits an owner who wants a performance catamaran at full superyacht scale with a crew to match. It rewards those who host large groups and want speed as well as space. Buyers who love the Ultima character but need flagship volume will find their yacht here. It is the summit of the performance range. It fits the owner who refuses to trade the thrill of a quick hull for the space of a big yacht.

It also stands as a headline charter asset where pace and luxury sell together at the top of the market. The flybridge and beach club give it real host presence. For an owner ready for a crewed superyacht that still drives with purpose, the 88 delivers. Life aboard is grand, quick and refined. The strong charter demand gives an owner a practical way to carry the cost of a flagship build.

Who it is for: Owners who want a crewed performance catamaran at full superyacht scale without losing the Ultima's pace and character.
