A Full-Beam Master Suite with a Private Sauna: Inside Sunreef’s 28.40-Meter Build
Shipyard Expansion in Ras Al Khaimah
Sunreef Yachts has marked a distinct milestone in its production history by building the first ULTIMA 88 at its Ras Al Khaimah facility. Constructed from advanced composites, this 28.40-meter vessel serves as the foundational model for a series optimized for long-range cruising efficiency. By establishing operations at this specific shipyard, the builder has increased its capacity to manufacture complex multihull geometries, ensuring that advanced engineering and high-end naval architecture are fully integrated right from the initial molding process.
Hybridizing Monohull Agility and Multihull Volume
The naval architecture of the ULTIMA 88 addresses a frequent compromise in yacht design by pairing the structural agility of a monohull with the stabilization benefits of a multihull. Aerodynamic exterior lines and an optimized hull geometry reduce drag while maintaining a wide 9.30-meter beam. This deliberate combination provides exceptional handling and smooth maneuverability, which allows captains to negotiate tight marina berths and navigate shallow, secluded coastal anchorages that are typically inaccessible to deeper displacement hulls.
Engineering the Walkaround Ocean Lounge
At anchor, the aft section of the yacht functions as a specialized waterside retreat. The engineering incorporates heavy-duty folding bulwark platforms that lower horizontally, expanding the usable deck footprint into a continuous, walkaround lounge area. This configuration connects a vast aft platform with custom sea-stairs and an integrated garage designed for smart water toy storage. Owners looking for heightened technical capabilities can also select a hydrofoil option, which lifts the composite hull to decrease friction and optimize top speeds.
Comparative Technical Foundations
The shipyard is offering the vessel in two distinct variations to cater to different operational profiles. The Classic Version utilizes traditional Volvo D13-IPS 1050 engines and provides a massive 387 square meters of internal living space, relying on a 6,000-liter fuel capacity for long-distance transit. Alternatively, the Eco Version integrates ultralight, highly flexible solar panels across the superstructure. This setup charges an advanced battery bank ranging from 22kW to 75kW, enabling silent electric cruising through an alternative hybrid propulsion system.
Saunas and Spatial Layouts
The interior configuration, developed entirely in-house by Sunreef Yachts, maximizes the natural flow of light across the main living areas. The layout features a full-beam master suite equipped with its own private sauna, offering a level of relaxation hardware rarely found on vessels under 30 meters. Beautifully appointed guest cabins complement the social spaces, arranging the furniture to emphasize real-world utility over purely decorative layouts. The result demonstrates that efficient, high-performance catamaran hulls can host expansive, luxury-tier environments.
