At sea, space is the final frontier. German firm Ultimate Catamarans has partnered with the experienced Croatian shipyard Iskra and renowned Italian design studio Luxury Projects to produce a line of innovative aluminium-hull power catamarans with deck spaces and internal volumes far larger than anything built before.
“The amount of space is unrivalled in their class,” says Ralph Wuttke, founder and owner of Ultimate Catamarans – hence the name Spaceline.
“There is no other company offering a range this size in aluminium,” Wuttke adds. “The [26.7-metre] SL88 is where they stop – that’s where we start.”
Out of this world
Ultimate Catamarans’ flagship envelops 800GT in a sub-50-metre length. The catamaran platform allows for 1,591 square metres of total space across four decks, a little over half of which is indoors. Here, everything is super-sized: the open sundeck measures 150 square metres, the bathing platform is 36 square metres, the four guest cabins are a generous 35 square metres each and the huge owner’s suite gets two balconies.
The 360-walkaround bridge deck has two main configuration options: the 150-square-metre aft section can be used for a helicopter landing deck or given over to an 18-square-metre main pool and sunpads, complementing the sundeck spa pool.
At the heart of Ultimate Catamarans’ revolutionary approach lies the yachts’ aluminium construction, which brings unparalleled strength and durability, while the dual-hull platform offers very high stability. These are yachts that can cross oceans on their own keel.
Design, quality and guest experience extend across the line. With comfort paramount, all spaces are extremely generous, no matter what the LOA. Frame spacing of 50 centimetres makes layouts fully customisable to the owner’s vision.
In Ultimate Catamarans’ suggested GA, the SL150’s full-beam owner’s suite is 80 square metres; even on the entry-level SL88, guest cabins measure at least 25 square metres.
“We have the largest guest cabins on the market,” says sales director Olaf Steckstor, “and the largest beds, at 200 by 220 centimetres. Ceiling height is 2.2 metres – no more bending or squeezing.”
All guest cabins on the SL150, 120 and 88 are on the main deck, ensuring an immediate connection to the water. “Each features its own private balcony, bringing the ocean’s embrace to your doorstep,” Wuttke adds.
Multi-award-winning designer Laura Pomponi of Luxury Projects brings her eye for understated luxury to the interiors. Owners have a broad palette of quality, timeless and durable fabrics and leathers to choose from. “These are interiors to be touched, felt and used,” Pomponi says.
At less than 37 metres in length, the SL120 can accommodate 12 guests. The large, open sundeck has seating, dining for 12, a bar and a six-person spa pool and sunpads. The bridge deck offers 140 square metres of outdoor space and a 68-square-metre indoor lounge and dining area, plus a separate gym and a spa with a massage area, steam room and sauna.
The entry-level SL88 offers a generous 721 square metres of outdoor space and 460 indoors. Configured here as a winter garden for indoor/outdoor living, the 45-square-metre sundeck gives amazing views through full-height glazing. Accommodation on the main deck is in four similar-sized cabins, each with its own balcony and five-square-metre en suite. The main deck saloon and dining area benefit from the boat's full beam, and there is a 30-square-metre swim platform and plenty of storage for water toys.
SL150YS (Yacht Support) takes the platform of the SL150 and turns it into a vast-volume supplementary vessel capable of travelling 5,000 nautical miles while being IMO Tier III compliant. Guests are accommodated on the open sundeck and bridge deck, where they can relax and enjoy snacks in the lounge while waiting for the helicopter to arrive. For longer stays, there are also two 26-square-metre double cabins.
On the main deck, double side-loading cranes hoist tenders into a giant 166-square-metre garage with more than enough storage for jet skis, Seabobs and other toys. Two or three more tenders can be carried aft. A swim/dive platform and multi-purpose garage sit below, equal in size to the SL150. Crew quarters are substantial, including a large mess and galley and a hospital.
Innovation meets luxury
Created with environmental responsibility in mind, the Spaceline yachts are outfitted with the latest diesel-electric and hybrid propulsion systems, including solar panels, and hydrogen technology is an option. A multiple-generation plant plus battery set delivers up to 15 hours of power at full demand, while a recovery system reuses heat from the generators without any waste.
All this brings what Steckstor calls “economic sensibility”. “Operational and fuel costs are notably lower compared to monohull superyachts of similar interior space,” he says. “It’s a pragmatic solution for those who value elegance with a conscience.”
The financial benefits don’t end there, as the initial outlay is also lower than it would be for other yachts. “Price-wise, our cats are about 30 per cent less than a monohull, with the same guest interior space and more exterior space,” says Steckstor. “And they are very complete, as the price includes rooftop exhaust, hybrid power train and interior and exterior customisation.”
Ultimate Catamarans hails its Spaceline as “encapsulating the essence of a new maritime era”.
“Spaceline is where innovation, elegance and sustainability unite to create an unparalleled adventure,” Wuttke says. “These catamarans beckon you to embrace a lifestyle that knows no limits.”
