British design studio Tony Castro Yachts has revealed SAMY, a striking new 68-metre sail-assisted motor yacht concept designed to combine long-range cruising with enhanced efficiency and sustainability.

Developed around an innovative system of inflatable sails and retractable masts, SAMY aims to reduce fuel consumption while maintaining the comfort and luxury expected of a modern superyacht. Unlike traditional sail-assisted concepts, the yacht’s propulsion system has been fully integrated into the vessel’s architecture from the earliest design stages, allowing the hull and superstructure to be optimised around the sailing technology.
According to Tony Castro Yachts, the inflatable sail system delivers significant propulsion across a wide range of wind conditions while reducing windage, improving safety and minimising the need for bulky deck equipment. The retractable masts and rotating booms are seamlessly incorporated into the yacht’s profile, preserving clean exterior lines and maximising guest spaces.
Sustainability is at the heart of the concept. The studio estimates that a typical Mediterranean-to-Caribbean round trip could save more than 33,000 litres of fuel, significantly reducing operating costs and environmental impact. Additional renewable energy sources, including integrated solar panels and modern wind turbines, further enhance the yacht’s energy efficiency.

With an estimated volume of 1,148GT, SAMY offers accommodation for 14 guests across seven luxurious cabins, supported by a crew of 16 plus the captain. The yacht’s leisure facilities include a spacious beach club with a swimming pool, large sunbathing areas, an alfresco dining space for 12 guests, a private Jacuzzi lounge on the upper deck and an impressive selection of water toys, including WaveRunners, a Nemo submarine, a nine-metre limousine tender and a six-metre RIB.
Key specifications include an 11.9-metre beam and a three-metre draft, providing a balance between interior volume and cruising versatility.
Commenting on the project, renowned yacht designer Tony Castro highlighted the importance of longevity in sustainable yacht design, noting that many yachts designed by his studio in the 1980s remain actively enjoyed today.
By combining innovative sail-assisted technology with luxury superyacht living, SAMY presents a forward-thinking vision for the future of efficient long-range cruising.
