The Sunreef Ultima Range
The Sunreef Ultima Range: Sleek, Fast Eco Powercats (first look at the 55 in Barcelona)
In recent years, Sunreef Yachts has been busy rewriting the playbook that it invented. Long known for big, beamy luxury multihulls, the Polish builder (now also building in Ras Al Khaimah, UAE) is pushing new ideas.
The latest design to come out of the Innovation Room is the Ultima line: a family of hybrid “ecospeeders” that promise monohull pace with multihull volume and efficiency.
The range spans 44, 55, 66, 77, 88 and 111 feet, all built around a lower-drag hull form, composite-integrated solar, and hybrid drivetrains.
We saw the Ultima 55 at the Barcelona Salon Nautico (International Boat Show, 8–12 Oct 2025), where it drew a steady crowd- helped by dealer previews and the show listing itself. The boat’s stance is striking: a narrow waterline beam for speed, with fold-down bulwarks that transform the aft cockpit into a beach-club when you’re at anchor.
What’s New?
Sunreef’s latest eco push isn’t new – the brand pioneered composite-integrated solar panels and lightweight battery banks across its Eco line – but Ultima packages that technical expertise into a fast, light, sportier platform.
The brief is clear: 25-knot+ cruising, 33–36-knot top end (and more with upgrades), and lower fuel burn versus like-for-like monohulls, with solar assisting loads and hybrid variants offering electric running. Sunreef offer multiple propulsion choices: from twin Volvo IPS diesels (D6-IPS650 or D8-IPS800) to a hybrid spec pairing 2× 350 kW e-motors with 2× 600 hp thermic engines.
Inside, the 55 swaps the typical raised saloon for a semi-open lounge that flows onto the aft deck, flanked by fold-down terraces. Side decks are true walkarounds, and the foredeck is a big living space. It’s got a “dayboat-meets-weekender” vibe – yet with the privacy and storage you expect on a cruising cat.

First Impressions from Barcelona
At the show, the 55 looks the business. The walkaround deck and wide, airy cockpit feel more like a 60-footer, yet the slimmer beam means easier marina access and higher pace than wider cats. The fold-downs are a real step-change at anchor: boarding the tender or spreading out loungers feels super-yachty without the weight of a full hydraulic platform. The helm ergonomics are IPS-friendly – joystick docking will suit owner-operators moving up from premium weekenders.
Where the Ultima 55 fits – and who it’s up against
- Bluegame BG54 / BGM75: If you’re cat-curious but style-driven, Bluegame looms large. The BG54 is a fast, open monohull with similar length and speed; the BGM75 is Bluegame’s sleek multihull flagship. Bluegame stresses efficiency and joystick ease; BGM75 claims monohull-like elegance in a multi footprint. The Sunreef competes with its solar/hybrid depth and those convertible terraces in a smaller package.
- Prestige M48: A popular production powercat that majors on volume and comfort at ~49’. Slower (16–20-kt cruise/peak packages), but keenly priced and very liveable. The Ultima 55 feels sportier, faster, more bespoke and is priced accordingly.
- Aquila 54: Big-beam cruising cat with serious interior space and range, typically less about speed. If you want max beam and cabins, Aquila wins; if you want pace and eco-tech, the Ultima 55 nudges it.
- Silent 60: The benchmark solar-electric cruiser. Slower (6–8-kt solar cruise; teens max) but near-silent and ultra-efficient with big solar arrays and battery banks. The Ultima swaps the quiet life for higher speed + hybrid flexibility. You pick the direction.
Verdict
The Sunreef Ultima 55 is building a new powercat category. With the low-drag, low-consumption logic of a multihull while delivering IPS-style handling and 30-knot performance, backed upby Sunreef’s Eco tech stack (solar-integrated composite, light batteries, hybrid options).
If you are after Mediterranean or Florida day-to-week cruising with frequent marina hops, this range will let you arrive fast, lounge wide, and run lighter.
