YERSIN: One-of-a-kind Sustainable Discovery Vessel For Sale

YERSIN was built in 2015 and since her launch has proven to be a true pedigree sustainable discovery vessel. Recognized as one of the cleanest explorer motor yachts in the world, YERSIN can cruise everywhere in the world and make a clean passage: zero emissions, zero wastes, whatever the location. Make your make without leaving a trace.

In her design, YERSIN brings to the fore some of the most innovative new technologies, whilst maintaining all of the comfort and luxuries expected of a superyacht - from an elevator that connects all guest decks together to a gym, spa, hammam, and massage room.

As a pedigree sustainable discovery vessel, she is also equipped with facilities needed on any discovery voyage - a research laboratory for investigation, a conference room, media room, hospital, and professional diving facilities.

YERSIN has been the vessel of choice for many prestigious explorations, including the Exploration de Monaco 2017, which saw her travel the globe for three years of scientific exploration, reaching the archipelagos of Micronesia and crossing the Atlantic to Martinique.

Aside from her explorative history, YERSIN makes a mark on the industry as one of the world's most sustainable yachts. Piriou, the French Shipyard commissioned for the build, used materials enabling YERSIN to be 95% recyclable. Her engines were designed to achieve extremely low fuel consumption and expel low emissions through filters which reduce nitrogen and sulfur oxides by 99.8%. Her dynamic positioning enables her to have no anchoring impact and her wastewater treatment is rated as 60% cleaner than the international standard. 

She is a maritime masterpiece dedicated to science and discovery with all the luxuries of a modern yacht, accommodating up to 18 guests.

Adventure, Science, Education - About Alexandre Yersin and ASE

In the spirit of adventure, the vessel was named after explorer, scientific cartographer, physician and bacteriologist Alexandre Yersin. Among his many achievements was co-discovering the bacillus responsible for the bubonic plague, which was later named in his honour, Yersinia pestis. His remarkable discovery saved countless lives.

The vessel shares the values of her namesake: Adventure, Science and Education (ASE).
“When the boat did not exist, it was very difficult to make people understand what it would be. Is there any other boat like Yersin? No, not really. I think we are the only one.”
