After presenting the first ocean-going production yachts in the world that are fully sustainable and powered by solar energy, Silent-Yachts now is the first boat builder to date to design and build boats for the use of a kite sail system.
The new Silent 60 solar powered catamaran carries 42 solar panels for 17 kWp of solar energy to power two electric motors of up to 2x340kw. Backed up by a battery capacity of up to 286 kWh, the yacht can cruise efficiently with zero emissions solely on solar power for up to 100 nautical miles a day for weeks.
To further improve its green credentials and range, for longer crossings the first Silent 60 is also fitted with a compact 9 or 13 sq. m kite wing.
“The main advantages of a kite over a conventional sail system are that it does not throw shade on the solar panels, does not need a tall mast, and generates up to 10 times more power per square meter than a traditional sail. In addition to that it saves about 1,5 tons of weight compared to conventional rigg and costs much less,” says Michael Köhler, Silent-Yachts founder and CEO.
“We tested the performance on different headings and at wind angles of up to 40 degrees with the 9 sq. m kite,” says Silent-Yachts’ Captain Mike Wandler. “Unlike a conventional sailing boat, the best results were directly downwind. Under kite power with no engines on or propellers turning, the boat speed was between 4 and 5 knots. We then switched on the electric motors drawing just 1kW each to reduce drag from the propellers and improve the flow of water over the rudders for better steering, this led to boat speeds from 6 to 7 knots over the same headings – a significant improvement on our original predictions.”
A big advantage of a kite compared to a conventional sail is, that the kite flies in much higher altitudes and therefore gets more steady and stronger winds up there. Therefore, it can already be used at low wind speeds of less than 10 knots, when it would not make any sense to hoist a sail on a sailing boat of comparable size.
The first Silent 60 can accommodate eight guest cabins on the lower deck, including a master suite, but other layout solutions are available. The social areas on board include an airy main salon, an aft cockpit, a cosy bow area and a flybridge.
Thanks to a draft of under 1m the yacht can access shallow bays, a crucial consideration for cruising grounds in the Caribbean and South East Asia. Two swimming platforms in the stern can be extended on owner’s request to carry a pair of electric jet skis. The lifting hydraulic platform between the two platforms can carry a 4 meter tender.
The yacht is designed to go everywhere as a true bluewater cruising yacht. The solar-electric system is configured to power all the on-board systems without the need of fossil fuels for a generator. Featuring a new, high-performance hull form with a longer waterline and reverse bow, the yacht has a cruising speed of 6-8 knots, but can reach 20 knots if needed.
Silent-Yachts is producing the world’s first fully solar-sustainable oceangoing production catamaran yachts. They are powered exclusively by solar energy and capable of cruising up to 100 miles per day. In 2009, founders Heike and Michael Köhler, who have spent 6,000 days cruising more than 75,000 miles all around the world, launched the Solarwave 46, the first fully self-sufficient blue-water catamaran after years of testing solar-powered propulsion, and they have been building boats ever since.

The 50-meter Heesen motor yacht Bijin has completed a comprehensive refit at Monaco Marine's La Seyne-sur-Mer facility. Formerly named Sibelle, the vessel was sold in October 2024 with Burgess representing the buyer and Ocean Independence the seller.The nine-month project involved exterior repainting from oyster white and grey to Matterhorn white with jet black accents and a red boot stripe. Interior updates focused on Japandi-inspired design elements blending Japanese minimalism with Scandinavian influences. Milan-based studio Hot Lab led the design in collaboration with Austrian contractors List GC.Hot Lab design director Enrico Lumini stated: "Their hands-on involvement and constructive approach were instrumental in helping us navigate challenges and complete the project within the established timeframe." The owners maintained an active role throughout the process, having previously worked with the design studio.Refit work concentrated on soft furnishings including beds, headboards, curtains, carpets, and loose furniture rather than structural modifications. The color palette shifted toward lighter tones and softer brown shades to create what the owner described as "an organic, naturally blending and appealing design" for guest relaxation.Originally delivered in 2015 with a Fast Displacement Hull Form design, Bijin received recognition at the 2016 World Superyacht Awards. The yacht accommodates 10 guests with an owner's suite featuring dual bathrooms serving as buffer zones before the main cabin.Monaco Marine project manager Augustin Fabre noted the refit met "the most demanding standards" for visual identity and functionality. The yacht will operate for both private use and charter in the Western Mediterranean, with initial seasons fully booked.The refit demonstrates continued market activity in large yacht refurbishment projects, particularly for well-maintained vessels requiring aesthetic updates rather than technical overhauls. The collaboration between ownership, design teams, and shipyard resulted in a nine-month completion timeline.Heesen Yachts is a Dutch ship building company that specializes in custom-built superyachts in aluminum and steel from 30m to 70m in size. Founded in 1978, it has launched more than 170 yachts since its inception.Credits: Viken Group

Azimut has developed Neuron, a fully digital yacht management system designed to streamline vessel operation and maintenance. The system was created by Azimut Technical Development in partnership with MDP Tech following a six-month trial installation aboard an Azimut Fly 53 model.Neuron enables remote monitoring and control of onboard systems including lighting, climate control, and entertainment through a customizable interface. The system reduces routine and extraordinary maintenance requirements by approximately 70% through continuous diagnostics and remote troubleshooting capabilities. According to the company, the technology allows after-sales technicians to perform system diagnostics while maintaining customer privacy protections.Technical specifications include a 50% reduction in wiring weight compared to conventional systems, freeing space for other functions. The plug-and-play architecture permits rapid component replacement, starting with control units. Power management features adjust electricity consumption based on real-time requirements.Azimut Technical Director Ruggero Gandolfi stated: "Neuron truly improves the owner's life, not only allowing them to monitor their vessel from home and directly manage certain systems with great ease, but also performing diagnostic tests and reducing unscheduled maintenance."The system is scheduled to become standard equipment on Azimut models up to 24 meters (80 feet) following final verification testing. The development represents Azimut's continued investment in digitalization projects aimed at enhancing owner experience and operational efficiency.Neuron's architecture incorporates risk analysis protocols to minimize system disruptions both at sea and in port. The technology will be rolled out across Azimut's production lines as part of the company's ongoing digital transformation initiatives in yacht manufacturing and support services.Azimut, founded in 1969 by Paolo Vitelli and part of the Azimut|Benetti Group, builds motor yachts from 42 to 144 feet across seven series. The company maintains production facilities in five Italian locations and one in Brazil, and has a global network of sales and service centres.Credits: Azimut
