55 Sunreef 2026 Boat for Sale

Ultima 55 Boat | 55' Sunreef 2026

2026 Sunreef Ultima 55 – New Build, Miami

Not for sale to U.S. residents while in U.S. waters.

The Ultima 55 is Sunreef's answer to a question the power catamaran market hasn't really had a good answer for: can a multihull actually be fast, fun, and beautiful — not just spacious? Buyers cross-shopping the Lagoon Sixty 5, Fountaine Pajot MY6, and Aquila 54 will find the Ultima 55 plays in a different league on performance, design language, and build quality.

At 17 meters with twin Volvo Penta D6 IPS 650 pod drives putting out 960 hp combined, she cruises at 20–24 knots and tops out around 35. That's express cruiser territory in a hull form that gives you a 7.6-meter beam at anchor, walk-around decks, and the rock-steady stability only a catamaran delivers — and it's a meaningful step up from the 18–22 knot top speeds typical of comparable Lagoon, Fountaine Pajot, and Aquila power cats in this size class. Joystick docking and twin bow thrusters make her genuinely easy to handle for an owner-operator.

What sets this build apart is the spec sheet. Most power cats in this range are configured for charter-fleet duty. This one is configured like a private flagship. The Sunreef WETRA 43" integrated control system runs the boat from a single glass interface, backed by a full Garmin electronics suite — radar, autopilot, GPS, AIS, dual-station VHF. Climate is handled by an upgraded 70,000 BTU air conditioning system, water by a 60 L/h watermaker, power by a 10.5 kW generator paired with a 15.6 kWh lithium battery bank for quiet nights at anchor.

The exterior is where she really separates from the pack. Folding side platforms drop down to extend the usable beam from 5.6 m underway to 7.6 m at anchor — turning the cockpit and aft deck into a private waterline lounge, a signature Sunreef feature you won't find on Lagoon or Fountaine Pajot in this range. Carbon extendable cockpit table, synthetic teak decking, generous sunpads forward and aft, davit-launched tender, electric swim platform, and underwater LED lighting throughout.

Inside, customizable cabin configurations, electric heads with fresh water flush, 43" lifting saloon TV, 32" TVs in the cabins, Fusion Apollo audio with subwoofer and Apple AirPlay, and Sunreef's signature interior finishes.

She's a 2026 new build, delivered and ready in Miami — no waiting list, no European delivery logistics, and immediately available where Sunreef's custom order book typically runs 18–24 months.
