In 2001 Boris was the youngest and only German to participate in the Mini Transat race, a singlehanded yacht race across the Atlantic where he finished in eleventh place. In 2006 Herrmann finished second in the European Championship as well as in the German Championship in the 505 class.
In 2008 Herrmann sailed his Class 40 yacht "Beluga Racer" into second place in the Artemis Transat, the oldest transatlantic race for yachts sailed singlehanded. Boris went on to win the Portimão Global Ocean Race, a five-leg round the world race on Class 40 boats. He and his co-skipper Felix Oehme won three of the five legs of the race.
In 2010, he raced in the Barcelona World Race with co-skipper Ryan Breymaier and finished in 5th place. During 2016 Boris crewed on the GC32 Malizia as part of Pierre Casiraghi's team for the GC32 Racing Tour. In August 2017, with the support of The Yacht Club de Monaco, Malizia II was founded and Boris and Pierre sailed her in the Rolex Fastnet Race and bagged the third spot on the podium. In 2018 they competed in the Monaco Globe Series and then Boris went on to compete singlehanded in the Route du Rhum 2018 securing 5th place.
The Malizia IMOCA project was founded in 2017 by Pierre Casiraghi and Boris Herrmann with the support of the Yacht Club de Monaco in order to realise a dream of sailing in the Vendee Globe and have Monaco's commitment to the sport realised through this ambition. In 2020 Kuehne + Nagel joined the team as a joint title partner and Malizia was renamed as Seaexplorer - Yacht Club de Monaco with major updates to the boat to create a competitive edge.
The Malizia Ocean Challenge
In 2018, Boris and Pierre founded the Malizia Ocean Challenge project.This initiative aims to combine sailing, science and education to get children fascinated about sailing and ocean topics whilst teaching them about climate change and to love our seas with our kids’ ocean challenge kit. We have got over 10,000 children involved in this topic to date. At the same time, we carry an on-board sensor to measure the CO2 in the ocean in remote, hard to reach locations and this data is then sent to our scientific partners at Geomar and the Max Planck Institute.
