Yersin was built by the French shipyard Piriou who successfully combined a very high level of technicality with the elegance of an exceptional ship.

Optimum safety

  • S.O.L.A.S Polar Passenger ship construction
  • Fiber optic gyro compasses
  • Reinforced ice classed hull
  • 8 watertight compartments
  • 4 Compartimented stabilisation units
  • Six diesel alternators
  • Three independants propulsion systems
  • Two 22 passengers life boats
  • Four 25 passengers life-rafts

Built as “S.O.L.A.S, Cleanship, ICE 1C Passenger Ship”, she provides the top maritime safety standards to date. Yersin can access the world’s most remote destinations and ice covered areas with her reinforced hull over her entire length. She is designed for long-range transoceanic sailing in extreme conditions (-20 C°, + 50 C°) on oceans, rivers and lakes, with a high degree of reliability in all weather and seas conditions. The vessel integrates clean technologies to ensure a minimal impact on the ocean, taking environmental friendliness to new heights.

Her ethos is “leave a track not a trace”.

Environmentally friendly

  • Vessel built to be 95% recyclable
  • Extremely low fuel consumption and low exhaust gaz emissions
  • Bureau Veritas Clean Ship Classified
  • Non-Teak recyclable resin decks
  • Underwater hull coated with silicon non-biocide antifouling
  • Bilge water separator treatment plant rated at 5ppm, 60% cleaner than the 15ppm international rule
  • Dynamic positioning, no anchoring impact
  • Exhaust gas filters on all engines, reducing NOx and SOx emissions and retaining 99.8% of soot particles
  • Advanced wastewater treatment and recycling plants
  • Black & grey water storage, up to 10 days

Yersin has a remarkable fuel efficiency. At a cruising speed of 11 knots, her electric propulsion gives the ship a consumption rate of 360-litres of fuel per hour, at nine knots, the consumption drops to 180-litres per hour.
Her biological treatment plant recycles all waste-water. Some UV lights eradicate the remaining bacteria, this water can be used to ballast or wash the deck. A waste-water ballast are preferred instead of seawater in order to prevent the spread of invasive species across the ocean. Yersin engines exhaust circulates through Particle filters to prevent 99.8% of the soot from entering the atmosphere.

Yersin uses artificial teak, a greener and hardier alternative to traditional teak wood on deck, an endangered species, traditionally used on yachts decks. A GPS positioning system keeps the yacht in position avoiding to drop an anchor on a fragile marine ecosystems.

Yersin waste water treatment and management system allows us to visits and stay up to 10 days in a pristine area.

Dr. Yersin

Dr. Yersin, the evidence

The name of the boat had to resonate with the project, a name that “sticks” to the words Adventure, Science, Education. The name of Yersin was imposed by himself. Dr. Alexandre Yersin (1863 – 1943) is little known from the public. Yet we owe much to him. He worked with the famous doctors Pasteur, Roux and Calmette. He was doctor of the Méssageries Maritime and discovered Indochina where he will live fifty years. He founded the Pasteur Institute of Nha Trang and the Medical School of Hanoi (1902). His fame is due to his research on diphtheria toxin and his discovery of the plague bacillus (1894). He acclimates the rubber tree (one of the current greatest resources of Vietnam) and the Quinine tree. From 1902 to his death he devoted himself to the local populations of Vietnam. He also discovered the Dalat which became a climatic station.

To summarize, Dr. Alexandre Yersin was a great Adventurer, Scientist, Educator.
