The only downside to this technology, which has already been used by Fountaine Pajot and Sunreef Yachts, is the supply of hydrogen in ports. In addition to its carbon tanks, the HS 80 is equipped with bifacial solar panels and high-performance batteries. The multi-yacht is also equipped with an AI-assisted autonomous navigation system and intelligent LED interior lighting. The interior layout, made using high-end sustainable materials, features 4 cabins and the same number of bathrooms. There are two additional crew cabins.
