Berlin-based yacht designer Theodoros Fotiadis has unveiled his latest project, a 140-meter (460-foot) trimaran yacht concept named Spear. The futuristic new multihull is the result of a collaboration with Lateral Naval Architects and is designed for adventurous yachtsmen who want to experience luxury cruising but are not willing to compromise on performance.
Over the last few years, multihulls have been gaining more popularity among people who dream of setting sail and living a life of freedom and adventure on the water. Catamarans, in particular, have been an increasingly popular choice among cruisers due to the fact that the looks, handling, and performance of this type of watercraft have improved considerably lately.
Nowadays, multihulls can easily compete with the most opulent monohull yachts in terms of styling while also offering increased stability, far more living space, and usually better performance than similarly sized monohulls.
The Spear project is an innovative, efficiency-optimized design that aims to blur the lines between absolute comfort and utility. Besides unprecedented deck space and internal volumes, the vessel promises enhanced hydrodynamic efficiency with a sharp, pointed silhouette characterized by sleek, aerodynamic lines from bow to stern despite its impressive beam of 23 meters (75 feet) and an elongated reverse bow that will efficiently pierce through the waves. Moreover, it boasts an optimized hull design for high-speed cruising.
Increased useable space on board, enhanced stability, and impressive fuel efficiency for a reduced operational cost were among the designers' top priorities for this design. As a result, "Spear combines efficiency, comfort, and expansive open spaces to create an unparalleled cruising experience," as explained by the design team at Lateral Naval Architects.
So what does this efficiency-optimized design entail? It means that Spear would require 20 percent less propulsion power than a 110-meter (360-foot) monohull vessel at a generous cruise speed of 18 knots. To put things into perspective, the designers explain that the trimaran will have the power demands of a much smaller 80-meter (262-foot) yacht, all the while offering twice the useable gross tonnage (Spear offers an incredible interior volume of 4650 GT).
The larger dimensions of the trimaran allowed designers to envision it with a propulsion system that has a medium-speed engine at its core, an option most often found in large commercial vessels. This choice further helps to maximize fuel efficiency, offering a further 15% fuel saving per kW compared to a typical yacht's high-speed engine.
The sponsons have been specifically designed to store generous fuel tanks, which, combined with the reduced fuel demands, will allow the multihull to reach an impressive global range of over 7,500 nautical miles (13,890 km). What's more, the future-proof design of the fuel tanks ensures they will be able to hold renewable biofuels like methanol in the future.
Performance-wise, Spear will be able to comfortably reach a maximum speed of 21 knots. But at reduced speeds, the trimaran's engine has efficient excess capacity, so the designers endowed it with a PTO/PTI capable gearbox to allow it to harness the excess capacity to power the house loads when cruising.
As for the boat's configuration, the huge 75-foot beam and impressive interior volume of 4,650 GT mean the trimaran provides abundant outdoor and indoor living space onboard. It features generous deck spaces with enough room for several swimming pools, luxurious open-air lounging areas, and alfresco dining areas where guests will be able to socialize, bask in the sun, enjoy the views, and more.
The exterior will also display luxury features such as a touch-and-go helipad forward, a fabulous infinity pool on the main deck, and an upper deck Jacuzzi. Another highlight is the expansive beach club aft, which can be accessed via twin curved staircases and features unfolding bulwarks that not only increase the available space but also offer direct ocean access.
Compared with a monohull superyacht of the same length, the internal living space offered by Spear is enormous. The main deck is configured with a spacious lounge and dining area, with seating for up to 12 guests, as well as two guest staterooms located amidships, both with ensuite bathrooms.
The upper deck is exclusively dedicated to the owner of Spear, with a full-beam forward-facing master suite that comes accompanied by a private lounge, a luxurious ensuite with a bathtub, and a private deck with stunning views of the helipad and the surrounding ocean. The upper deck will also house an additional guest stateroom and convivial spaces like a lounge and dining area.
The lower deck is where the crew quarters are situated, while the captain's cabin can be found on the bridge deck.
The sleek, modern aesthetics and fuel-efficient design, coupled with the impressive top speed of 21 knots, global cruising range, and flexible system architecture designed to accommodate future renewable fuels, make Spear a truly innovative multihull concept that has the ability to inspire a paradigm shift in the yachting industry.
