Bill Gates' $645M Secret Hydrogen Superyacht To Make Splash At Monaco Yacht Show

A 390-foot superyacht named Breakthrough, designed to run entirely on liquid hydrogen, will be showcased at the Monaco Yacht Show. This groundbreaking vessel, reportedly once linked to Microsoft co-founder Bill Gates, is valued at $645 million. Breakthrough boasts luxurious amenities including fourteen balconies, two offices, a basketball court, and multiple libraries. While previously known as the "Bill Gates yacht" due to his intended purchase, Gates recently withdrew from acquiring it. The superyacht, also referred to as Project 821, has been associated with Gates for years, though he has never actually set foot on board. The vessel operates with a near-zero-diesel approach, positioning it as a highly environmentally advanced yacht. There are industry rumors that Canadian billionaire Patrick Dovigi might have been a potential buyer, but the yacht remains on the market. Breakthrough is described as the largest yacht attending the 2025 Monaco Yacht Show. The article notes the irony of billionaires promoting climate action while still utilizing private jets for travel.
