Green concept Yacht building

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. You can rest assured that we will not integrate every development on board just because it is new, but because it is a reliable and authentic product that make sense.

Green Energy

As our yachts are driven by the wind, our motivation ​​is to cover the electrical consumption on board primarily with CO2-neutral energy. The 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. 

The extra-large battery banks enable the air conditioning to run in eco mode throughout the night with enough spare amp-hours to wait the wind and sun. Our yachts are future proofed, ready to integrate 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 yachts. New, innovative developments such as Lignia as an equivalent teak substitute and sandwich materials made of flax or recycled PET bottles are used after sufficient testing.

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 also easy to maintain and repair on floorboards or walls. 

Energy Efficiency

Building a sailing yacht is in itself ecologically correct. Since we founded our shipyard, YYachts have already implemented a number of 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 kilowatt. That is our philosophy for a reliable and sustainable yacht.

Weight Efficiency

At YYachts we know that speed can only be achieved with light-weight construction. That is why YYachts are optimised 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

A special feature of YYachts are the vertical installation windows. They do not heat up the ships so much from the inside; In this respect, you can use our two-engine technology, the hydro-generator and our large battery banks to cool the yacht at any time overnight without leaving the generators running. Silence is golden.
