More than a speculative future concept, the AERA catamaran represents the convergence of mature technologies assembled with an emphasis on simplicity and sustainability. Research and testing have shown the project is both feasible and buildable. The focus now is on systems integration and production scaling.<img src="https://photo-assets.superyachttimes.com/photo/371664/image/large-bcc3594f61ee7b5986053ac54a532b0c.jpg" data-gid="gid://syiq/Photo/371664">Developed by <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a> in collaboration with sister company <a data-gid="gid://syiq/Company/458" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rondal B.V.

Rover Design (Company)">Cor D Rover</a>, AERA is a technical study into the feasibility of combining wind-dominant propulsion, low-drag hydrodynamics and alternative energy systems within the constraints of a large luxury yacht.&nbsp;The 50-metre catamaran builds on the shipyard’s Project Tidal Shift, an internal innovation initiative that identified increased utilisation of sail power and systemic reductions in energy demand as the most effective pathways towards sustainability. From the outset, the project followed an engineering-first methodology in which energy demand and drag were reduced before alternative energy sources were applied. This approach informed decisions across platform selection, structural engineering, rig design and onboard energy systems.“Early concept development did not initially assume either a multihull platform or a wing sail,” says Herman de Jong, innovation manager at <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a>. “Our initial investigations focused on automation of conventional rigs and the use of delivery sails to reduce dependence on costly sail inventories.”Collaboration with <a data-gid="gid://syiq/Company/7904" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Artemis Maritime (Company)">Artemis</a> introduced the possibility of wing-based propulsion, with early consideration given to soft wing concepts derived from high-performance foiling monohulls. These were ultimately rejected due to the large structural loads required to shape the membrane, the resulting rig forces transferred to the hull, and the limited suitability for the operational profile of a superyacht. A rigid wing sail was identified as aerodynamically superior, functioning as a true air-foil with 10 times lower drag than a conventional tube mast (even with the sails lowered), while also allowing passive feathering when unloaded.<img src="https://photo-assets.superyachttimes.com/photo/371695/image/large-f6fba2ad9ba66c269310feeea6a26fee.jpg" data-gid="gid://syiq/Photo/371695">Active control“Wing sails have been proven in racing environments such as the America’s Cup and <a data-gid="gid://syiq/Company/6878" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="SailGP (Company)">SailGP</a>,” argues Dr Iain Percy, founder and CEO of <a data-gid="gid://syiq/Company/7904" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Artemis Maritime (Company)">Artemis Technologies</a>, himself an AC veteran and double Olympic champion. “The challenge here is adapting that performance into a reliable, low-maintenance system suitable for a superyacht. To do that, a significant part of the development has focused on active control to manage performance, comfort and manoeuvring across a wide range of conditions.”Initial testing of the wing concept was conducted using a free-standing, rotating carbon-fibre wing mounted on a J22 test platform. The trials confirmed the wing’s ability to passively align with the wind and maintain low drag, but also revealed some dynamic coupling between the wing’s oscillatory behaviour and the natural roll frequency of the monohull. These findings convinced the team to focus on a multihull configuration, as the increased initial stability of a catamaran minimises roll-induced excitation of the wing system and the loads on the two sets of bearings inside the yacht, although <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a> does not preclude monohull applications in the future.<img src="https://photo-assets.superyachttimes.com/photo/371647/image/large-3db5887279a6542cf289be78a33db442.jpg" data-gid="gid://syiq/Photo/371647">“The wing sail concept is better suited to a catamaran platform as the rig remains upright and is not subjected to large heel-induced load variations,” explains de Jong. “By limiting heel angles, the vessel also avoids one of the primary deterrents for owners transitioning from motor yachts to sailing yachts, not to mention the absence of flogging sails and running rigging.”The wing comprises a thin aerodynamic Mylar skin supported by a carbon-fibre framework of spars, ribs and transverse plates, which manage the global bending and torsional loads much like the wings of an airplane. Controlled flexibility is incorporated into the design to allow the wing to twist under load, improving lift distribution and reducing peak stresses. <img src="https://photo-assets.superyachttimes.com/photo/371658/image/large-87c2c4becc7abb55160fd76750f46e73.jpg" data-gid="gid://syiq/Photo/371658">AutomationAutomation is fundamental to the operational viability of the wing system. Conventional sail handling is replaced by wing rotation and deflection of the four trailing-edge flaps, actuated by hydraulic cylinders at the root of each flap. Sensor-driven software continuously adjusts the wing’s angle of attack and flap configuration in response to wind conditions, reducing crew workload and minimising the risk of human error. The control algorithms are the result of CFD models developed in collaboration with Artemis, drawing on experience from high-performance sailing applications.&nbsp;Feathering is a critical safety feature, so if the active system fails the wing naturally aligns with the wind and minimises drag. In extreme or turbulent conditions, it is designed to depower automatically to a low-load, low-drag state without requiring crew intervention. Although it’s designed to remain upright in all weather conditions, a hydraulic hinge mechanism allows the entire wing to be lowered to reduce air draught for bridge clearance or maintenance purposes. <img src="https://photo-assets.superyachttimes.com/photo/393334/image/large-cbf9c3c68a163712f4ddc521e251b194.png" data-gid="gid://syiq/Photo/393334">From a lifecycle standpoint, Dr Percy points out that a wing sail replaces a consumable system with a permanent one. Conventional sails degrade and require regular replacement, whereas a properly designed wing can last for the life of the yacht. This permanence shifts cost and maintenance considerations away from periodic sail replacement towards upfront engineering and long-term reliability.“Manufacturing feasibility has also been a central consideration throughout development,” says Bart van der Meer, sailing system engineer at <a data-gid="gid://syiq/Company/458" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rondal B.V. (Company)">Rondal</a>. “Each rib of the wing requires a unique mould due to the changing airfoil geometry along the span. We expect production-scale moulds are expected to be fabricated from milled aluminium to ensure dimensional accuracy and repeatability.”Although these challenges are not trivial, they are a question of process optimisation rather than unresolved technical risk.<img src="https://photo-assets.superyachttimes.com/photo/393329/image/large-e0fb3f469c6062ee583c2c1998445a5c.jpg" data-gid="gid://syiq/Photo/393329">Built like a bridgeStructurally, the AERA catamaran departs from conventional multihull architecture through the use of principles derived from cantilevered bridge design – notably the historic Koningshaven Bridge (also known as ‘De Hef’) close to <a data-gid="gid://syiq/Company/43" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Cor D. Rover Design (Company)">Cor D Rover</a>’s studio in Rotterdam. The triangulated geometry spans large distances between pillars, enabling open-plan interiors and extensive glazing without visually dominant pillars.&nbsp;The asymmetrical geometry of the vessel is a functional response to spatial and structural requirements rather than an aesthetic gesture. Although the deck levels appear unsupported, structural integrity is maintained through clearly defined global load paths disguised in features such as staircases. <img src="https://photo-assets.superyachttimes.com/photo/371698/image/large-b28b9a6de23b265903ea61bfe20d603d.png" data-gid="gid://syiq/Photo/371698">“The geometry follows the forces rather than being applied as a stylistic layer,” explains <a data-gid="gid://syiq/Company/43" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Cor D. Rover Design (Company)">Cor D Rover</a>. “Structural cut-outs allow semi-open areas to remain outside the tonnage calculations while still contributing to stiffness and spatial articulation. Despite this unconventional arrangement, the enclosed volume is carefully controlled at approximately 1,880 cubic metres, keeping the vessel below the 500 GT threshold.”Material selection for the hull and superstructure is centred on aluminium, chosen for its strength-to-weight ratio, recyclability, and compatibility with <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a>’s expertise in working with lightweight aluminium alloys. Weight control is particularly critical for a catamaran, as increased mass directly raises wetted surface area and drag. <a data-gid="gid://syiq/Company/7904" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Artemis Maritime (Company)">Artemis Technologies</a> was closely involved in optimising the hull forms to balance hydrodynamic efficiency with superyacht functionality.“Our naval architects actually found the constraints of the superyacht design space to be a valuable tool in refining the hull shapes,” says Dr Percy. “By working within a predefined functional window that takes into account accommodation needs, utilities and other essential factors, they were able to focus on local optimisation and maximise the efficiency of the hull design.”<img src="https://photo-assets.superyachttimes.com/photo/393335/image/large-11dc06fc86174d979606f874bfc85d4a.png" data-gid="gid://syiq/Photo/393335">Energy generationEquipped with two retractable, forward-facing, azimuthing thrusters, AERA’s energy generation is organised around a hybrid diesel-electric architecture and 580-kWh battery bank for efficient integration of multiple power sources. <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a> installed a similar system on 60-metre <a data-gid="gid://syiq/Yacht/8258" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Sarissa59.7m (195'10&quot;)Royal Huisman2023">Sarissa</a> in 2023, but on AERA has added compressed hydrogen tanks for supplying a low-temperature PEM hydrogen fuel cell.

At these speeds, continuous power output of around 40 kW is achievable, sufficient to cover hotel loads and allow generators to remain offline. The fixed, low-drag hydrogenerators deliver optimal performance without the added complexity of retraction mechanisms – a solution that aligns with AERA’s ethos of simplicity and high efficiency.<img src="https://photo-assets.superyachttimes.com/photo/393328/image/large-15f017ba3b5bb5892a3a52ed2dc5ad1c.jpg" data-gid="gid://syiq/Photo/393328">“Our simulations show that during a typical cruising week, including one visit shoreside when shore power is available, the yacht will not need to run her variable-speed gensets for hotel loads,” says Jidde Looijenga, innovation manager at <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a>. “They are needed only during motoring or motor sailing to generate electricity for the retractable propulsion system.

Rover Design (Company)">Cor D Rover</a>, the shipyard team is exploring the integration of wind turbines to generate electrical power at anchor or in port. Any such system would be supplementary rather than critical and, as the designer notes, “would need to operate with very low noise and vibration to be acceptable in a yacht environment.” These ideas are not on the project’s critical path, but they illustrate potential future extensions of <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a>’s renewable energy strategy.<img src="https://photo-assets.superyachttimes.com/photo/393332/image/large-3aaca815d143ace4293d0ef4519ca552.png" data-gid="gid://syiq/Photo/393332">UsabilityBeyond technical feasibility, the AERA concept also addresses usability and the owner experience. The combination of automation, reduced manual sail handling, and increased comfort is intended to make sailing more accessible and as straightforward as operating a motor yacht.&nbsp;“Combined with reduced fuel consumption and lower operational emissions, this positions AERA as a bridge between motor and sailing yacht ownership,” says Looijenga.Overall, the catamaran represents a convergence of proven technologies and disciplined system integration rather than reliance on untested innovations. With its emphasis on simplicity, sustainability and lifecycle efficiency, the concept demonstrates that a wind-dominant, low-emission superyacht is technically achievable within available engineering and classification frameworks.<img src="https://photo-assets.superyachttimes.com/photo/371693/image/large-d494cdf4de75a63242521821d563f54f.png" data-gid="gid://syiq/Photo/371693">
