Ultimate Catamarans

Not just another superyacht. Designed around your life.

Engineered for safe passage across oceans.

Designed by experienced seafarers. Engineered by leading naval architects. Built in cooperation with one of Europe's most experienced aluminium catamaran shipyards. Styled by accomplished designers.

The owner should never adapt to the yacht.
The yacht should adapt to the owner.

That is why we bring the magic of a 90-meter superyacht — its comfort, its safety, its seakeeping — to a scale that remains yours, not the crew's.

The Lines

One Philosophy.
Three design lines.

The S-Line

Strong, straight, unmistakable.

S88|S120|S150

The S-Line is the classic expression of Ultimate Catamarans: straight, strong and unmistakable. From the S88 upwards, it brings substantial main-deck guest suites, exceptional privacy and usable space usually associated with much larger monohull yachts — with lower propulsion energy demand in comparable operating profiles. The portfolio currently includes the S88, S120 and S150, while the S180 and S210 are presented as concept studies illustrating the future direction of the brand. Every S-Line is built around her owner — layout and interior design are fully custom, tailored to your taste and wishes.

The best layouts are the ones created for a single owner.

For that reason, we do not publish our concept layouts.

They are part of a private design process, developed to inspire possibilities far beyond conventional yacht design and to help each owner discover what their own perfect yacht could become.

Every S-Line, Q-Line, Yacht Support and Full Custom yacht is entirely custom-built. There are no standard layouts, only ideas that evolve into a yacht shaped around your lifestyle, your wishes and your dreams.

Full Custom

When even our custom is not custom enough.

Full custom yacht design sketch

There are no predefined option lists, standard layouts or fixed owner configurations.
Every Ultimate Catamaran is individually developed around the owner's vision, operational requirements and lifestyle.

Private brief

Developed from the first line around your vision, your use and your way of living at sea.

Yacht Support Vessels

She carries everything the dream demands.

The YS150 combines yacht-support capability comparable to many 60 meter monohull support vessels with the inherent stability of a wide catamaran platform — a major advantage for over-side lifting, deployment and recovery operations. Up to five deployment and recovery stations can support parallel operations, giving owners and crew exceptional freedom to launch, recover and manage tenders, toys and specialist equipment without conventional operational bottlenecks.

YS15045.00 m · 150 ft

Wherever the yacht goes, she goes further.

The helicopter that extends your freedom of movement, the tenders that disappear over the reef, the dive team, the toys, the spares no one should ever have to think about — she carries them all, quietly, so the voyage above her remains pure. Up to 12 guests on board.

Propulsion

Advanced Hybrid Propulsion

Silent strength, intelligent efficiency.

Every Ultimate Catamaran combines an efficient aluminium catamaran hull form with Advanced Hybrid Propulsion as standard.

Compared with monohull yachts of similar usable space, the propulsion-energy demand can be reduced by up to 70%. The result is a quieter, smoother and more refined yacht, with lower vibration, reduced emissions, improved redundancy and a more peaceful experience on board.

For owners and guests, the difference is not only measured in efficiency. It is felt in silence, comfort and confidence at sea.

Optional Upgrade

TRI-HYBRID™ Propulsion

For owners seeking the next level of silence, independence and future-ready operation, TRI-HYBRID™ Propulsion is available as an advanced option.

It combines all advantages of Advanced Hybrid Propulsion with fuel cell technology as a third energy source. This enables selected operating phases in fully electric zero-emission mode, with near-zero noise and vibration and an exceptionally calm atmosphere on board.

The result is a superyacht experience closer to sailing: quiet movement, reduced environmental impact and a deeper connection with the sea, without compromising range, comfort or confidence.

  1. 01 — Diesel-Electric
    Range without compromise.

    Efficient aluminium catamaran hulls paired with diesel-electric generation deliver long, confident passages. Compared by usable guest interior space, not GT, an Ultimate Catamarans platform can require up to 70% less propulsion energy than a comparable monohull in similar operating profiles.

  2. 02 — Battery-Electric
    Silence on demand.

    Glide into anchorage on stored energy alone. Near-zero noise, no vibration, no exhaust — only the sound of the sea against the hull.

  3. 03 — Hydrogen Fuel Cell
    A third energy source.

    The optional TRI-HYBRID™ upgrade adds fuel-cell technology for selected zero-emission phases — a superyacht experience closer to sailing, without compromising range or comfort.

Tri-Hybrid Propulsion — three energy sources, one superior experience
Innovation with Purpose

Technology, in service of the experience.

Every choice we make has one purpose — to deepen the way an owner lives at sea.

Advanced Hybrid Propulsion

Quieter passages, smoother arrivals and effortless silent moments at anchor — standard on every yacht.

TRI-HYBRID™ — optional

An additional layer of energy autonomy for owners who want to push range and serenity even further.

Aluminium construction

Light, strong and enduring — a hull material the sea, your insurer and future owners all respect.

Efficiency and long range

Catamaran efficiency translates directly into longer cruising, fewer refuels and more horizons in a single season.

Comfort by design

Reduced noise, reduced vibration, more living space — comfort engineered into the way the yacht moves.

A Recurring Promise

Designed by Seafarers.

Decades of real-world experience aboard commercial vessels, naval ships and superyachts shape every Ultimate Catamaran. Layouts, flow, sightlines and silence — all decided by people who have stood the watches, lived the seasons and understood what a yacht must do when the horizon is the only address.

Confidence by Design

The quiet assurances behind every yacht.

German management

Founded and led from Germany, with the discipline and clarity owners expect.

Maritime professionals

A core team of captains, surveyors and naval architects with decades at sea.

Bespoke approach

No catalogues. No fixed options. Every yacht developed around its owner.

Proven shipbuilding partner

Built in cooperation with one of Europe's most established aluminium catamaran yards.

Commercial standards

Engineered to commercial shipbuilding standards — built to be trusted, season after season.

The Craft

Why aluminium.
Why this way.

Behind every line is the same hull philosophy. Aluminium is safe, lightweight and allows full customisation — the only honest material for a superyacht of this calibre.

50 cm

Frame spacing

Significantly closer than many conventional yacht structures. Engineered for strength, impact resistance and a calmer onboard experience — while allowing exceptional freedom for bespoke interior and layout customisation.

Aluminium

Non-combustible

No toxic fumes, no delamination, no osmosis. A material the sea, and the insurer, both respect.

Sprinklers

Full coverage

From the S88 onward, a complete sprinkler system covers the interior — virtually unseen in this size class.

ICCP

Dual cathodic protection

Passive anodes and an active impressed-current system together protect the hull for decades.

−70%

Propulsion energy at 12 kn

Compared by usable guest interior space, not GT, an Ultimate Catamarans platform can require up to 70% less propulsion energy than a comparable monohull in similar operating profiles.
