Sustainable yachts made in Germany

Y Green

Two of our core principles are to build yachts as “Green” as possible and at the same time, as “Safe” as possible. Sustainability and environmental friendliness are not just empty words at YYachts. It is one of our main pillars, not as corporate greenwashing but as the core of our projects.

You can rest assured that we will not integrate developments on board just because it is new and fancy. YYachts components have to be reliable and authentic products that make sense, bringing multiples benefits onboard.

The wind is free, and sailing is one of the cleanest and most ecologically ways to travel enjoying the holidays. We are making concrete efforts to reduce the use of fossil fuels onboard, minimizing the environmental footprint, adopting organic materials such as flax, and focusing on waste reductions.

Green Energy

Our goal is to cover the electrical consumption on board primarily with CO2-free energy.

Light, flexible, and highly efficient photovoltaic panels mounted on the bimini generate up to 55% of the boat’s daily energy requirement. Combined with the energy generated by the hydro-generator, the average daily consumption can be completely supplied by renewable energy. 

Especially YYachts YC is implemented with an innovative system to recover electrical energy during sailing. Thanks to special blades under the keel which are towed and set in motion while sailing, it is possible to come up with a green alternative to avoid diesel generators and their downsides.

The extra-large battery banks enable the air conditioning to run in eco mode throughout the night with enough backup energy to wait the wind and sun the following day. Our yachts are future-proofed, ready to integrate hydrogen fuel cell systems as soon as commercially available.

Sustainable Materials

We use the most sustainable materials wherever possible in the construction and finishing of our boats.

YYachts along the years has implemented many innovations, such as the Teak decks have been replaced with Lignia wood, natural wood with a much lower environmental footprint. This wood is an alternative to the classic Burmese Teak deck heavily involved in deforestation. Lignia wood is awarded the FSC label for its sustainable management and it also has greater wear, water salt, UV and wind resistance than traditional Teak.

Other new and innovative developments such as sandwich materials made of flax or recycled PET bottles are implemented in YYachts to substitute the traditional constriction materials. They bring several advantages for what regards the weight, noise absorption, strength and fireproof resistance.

Luxury is simplicity

Our interior designers are working with a variety of fabrics and alternatives to leather. We use compressed paper-based material for countertops, and this creates a modern and practical surface. It is also easy to maintain and repair on floorboards or walls. 

Entering a YYachts is a complete new sensorial fully rounded experience. Surely your view will be stimulated by a breath taking design but also by natural smells released by the natural perfumes of fine wood essences, leather, Alcantara and natural sustainable fibres from the upholstery.

Energy Efficiency

Building a sailing yacht is in itself ecologically correct. Since we founded our shipyard, YYachts have already implemented several challenging projects in terms of sustainability. For the Siemens Foundation, for example, we built a “green” explorer yacht for research into climate change, which is now operated by the Max Planck Institute. In this project, we gained a lot of experience in how to integrate electric and hybrid drives. In addition to the new and exciting technology, we also have to deliver yachts that are reliable at sea and do not cause any issues - unfortunately, the yacht industry per se tends to force developments too quickly that have not been tested enough at sea outside of the laboratory.

In order to combine our credo of simplicity with a quiet and environmentally friendly ship, we prefer to improve its autonomy. Instead of implementing complex high-voltage propulsion systems that can have unpredictable interactions with our carbon yachts and overwhelm normal crews, we operate the yacht with two engines, each with an extra alternator, which charges the large battery banks in less than ten hours. In addition, we install solar panels on the fixed bimini, which provide a further four to eight kilowatts of charging power during the day. And as a further source of energy, the "hydro drive" generates energy from the pure power of sailing at up to 7.5 kilowatts. That is our philosophy for a reliable and sustainable yacht.

Weight Efficiency

At YYachts we know that speed can only be achieved with lightweight construction. That is why YYachts are optimized in all details for low weight.

Cutting-edge modern design demands hulls and rigs in high-performance carbon, with an interior largely in modern sandwich construction, yet with the traditional look and feel of solid wood. Our innovative construction methods provide a lightweight advantage over conventionally built yachts, improving overall sailing properties. Particularly evident in the light and medium winds of the Mediterranean, our yachts continue to provide fun sailing when others are left to motor sail. 

YYachts are timeless and state-of-the-art.

Thermo balance

The coach roof is a cornerstone feature of all YYachts essential to guarantee a remarkable quantity of light in the saloon with a 360° view to the sea. Thanks to vertical windows and special ray-reflecting glass this avoids the overheating of the saloon and cabins below deck. In the summer days, the sun rays will never get directly inside the saloon, compared to the traditional angled windows.

Moreover, due to the prominent coach roof shapes over the vertical windows will ensure that only the light will come in filtering direct scorching sun rays. This feature ensures high energy efficiency, so the boat requires less energy to be cooled down in hot climates. 

For what regard coach roof in its horizontal components, is highly thermally isolated with composite sandwich materials to protect the interiors from the external summer heat and temperature fluctuations.

Therefore, it means a sensitive reduction in fuel consumption, less noise since generators and inverters will remain off for most of the time. The onboard energy supply is well calculated and the use of large battery banks in combination with large solar panels and a hydro generation system allows the yacht to be used even without a generator nearly all day and night.

Silence is golden.
