British naval architecture studio Dixon Yacht Design has revealed OXO, a 48.27-metre solar-powered superyacht concept designed to combine luxury cruising with significantly improved energy efficiency. Developed in collaboration with interior design studio Design Unlimited, the project integrates more than 100 square metres of solar panels into the yacht’s architecture.
According to its designers, the solar installation could generate between 70 and 90 kilowatt-hours of electricity per day in Mediterranean conditions, supplying approximately 20% of the vessel’s hotel load. That includes electricity used for onboard accommodation and guest facilities rather than propulsion.
Unlike conventional superyachts that add renewable-energy equipment after the initial design stage, OXO has been developed around a broader efficiency strategy. Its slender hull, carefully engineered stern, integrated solar panels and advanced propulsion options are intended to work together to reduce energy consumption without sacrificing luxury or comfort.

OXO’s solar array is one of the project’s defining features. More than 100 square metres of photovoltaic panels are integrated into the yacht’s exterior design rather than mounted as a separate addition.
The designers estimate that the panels could produce 70–90 kWh of electricity daily under favorable Mediterranean conditions, covering approximately one-fifth of the vessel’s hotel energy requirements.
This would help reduce reliance on onboard generators for everyday electricity consumption, although actual output would depend on sunlight, weather, operating patterns and equipment demand.
The concept also includes a substantial battery system, with a proposed capacity of 1.5–2.0 megawatt-hours.
OXO measures 48.27 metres in overall length, with a waterline length of 44.59 metres and a beam of 8.93 metres.
Its relatively long, slender hull is designed to reduce wave-making resistance, one of the forces that increases energy consumption as a vessel moves through water.
Dixon Yacht Design has also used computational fluid dynamics to optimize the stern sections, reducing transom immersion and associated drag.
These refinements are intended to improve efficiency during cruising, complementing the energy generated by the yacht’s solar panels.
The proposed propulsion system features twin MAN engines rated at approximately 1,050 horsepower each, connected to controllable-pitch Hundested propellers.
A hybrid propulsion arrangement is available as an option, giving a prospective owner flexibility when selecting the final machinery configuration.
The yacht is designed to achieve a maximum speed of approximately 16 knots.
Its aluminium hull and superstructure contribute to the project’s weight-conscious engineering approach.
British studio Design Unlimited has created a contemporary interior concept emphasizing natural light, understated luxury and comfortable living at sea.
The accommodation is designed for 10 guests in five staterooms, with spacious communal areas and a layout intended to support extended voyages.
Organic shapes, bespoke details and natural materials create a warm atmosphere, while large windows provide expansive views of the surrounding water.
The owner’s suite features a restrained palette of neutral tones, contemporary furnishings and carefully integrated lighting.
Outdoor areas include a spacious aft deck, foredeck lounging spaces and areas designed for alfresco relaxation and entertaining.
Despite its length of more than 48 metres, OXO has been designed with an internal volume of 499 gross tonnes.
The yacht’s principal dimensions include a hull length of 45.60 metres, a waterline length of 44.59 metres and a beam of 8.93 metres.
Keeping the project below 500 GT is a significant design consideration because some maritime regulatory requirements vary according to a vessel’s gross tonnage, flag and operating status.
OXO is currently presented as a ready-to-build design concept rather than a completed superyacht.
Dixon Yacht Design introduced the project around the 2026 Monaco Yacht Show, providing prospective owners with an opportunity to examine the design and its proposed engineering systems.
The final specification, shipyard selection, construction schedule and delivery date would depend on a future commission.
The project illustrates a growing direction in superyacht design: integrating energy efficiency into the hull, propulsion system and onboard architecture from the earliest planning stages.
