Fun facts
🧪 THE FIRST HYDROGEN YACHT:
“Breakthrough” made history as the world’s first hydrogen fuel-cell powered superyacht. After extensive sea trials in the North Sea, she was delivered to her owner in May 2025. Built by Dutch yard Feadship, the 118.8-metre vessel introduced a revolutionary propulsion: liquid hydrogen stored in cryogenic tanks feeding fuel cells for silent, zero-emission cruising.

🧪 HOW DOES THE HYDROGEN ACTUALLY WORK?
(yes, I actually researched this, I’m not an engineer but this is what I’ve understood)
Step 1 : Liquid hydrogen (LH₂) is delivered quayside by an industrial supplier and transferred to the yacht under cryogenic conditions (−253 °C / -423°F).
Step 2 : The liquid hydrogen is stored in a vacuum-insulated, double-walled cryogenic tank. Reported capacity ~92 m³ (4 tonnes). The double wall and insulation minimize boil-off and isolate the tank from the hull.
Step 3 : When used, the ‘MAN Cryo’ engine/system warms up the hydrogen, making it go from liquid to gas (LH₂ → GH₂) and prepares the gas hydrogen into the right temperature and pressure, and then delivered to the cells.
Step 4 : The 16x PEM modules convert that hydrogen (+ some added oxygen) into electricity and water (water being the waste in this case). Here it becomes interesting: that hydrogen is broken down into protons and electrons. The protons continue through the cells, but the electrons are blocked. Having no other place to go, they go into the wiring of the ship, and so, powering her.
Step 5 : That electricity is monitored by a supply unit that decides where is should go and what components to power.

🌍 WORLD’S LARGEST SALE EVER: Less than a year after delivery, “Breakthrough” changed hands in one of the world’s most significant brokerage yacht sales in history, an in-house deal by Edmiston (Sept 2025).
The transaction was rumored to be over $650 million!
Edmiston, which had managed the project for the original owner, noted that “Breakthrough” instantly became ‘the most exclusive yacht available for charter’ after the sale.

🎨 DESIGN: Conceived by British design studio RWD, “Breakthrough’s” design pushes boundaries.The exterior features:
• 14x retractable balconies
• 7x fold-out sea platforms immersing guests in their ocean surroundings
At the stern, an 8.2-meter glass-floored infinity pool with a contraflow system allows for both leisurely swims and exercise against the current.
Below decks, a semi-submerged ‘nemo lounge’ at the waterline lets guests observe marine life through huge underwater windows.
The yacht spans five decks above the water (plus two below), including a secluded four-deck owner’s apartment complete with two master suites, private offices (each with its own fireplace), a gym and a forward-facing jacuzzi.
Natural materials like fumed eucalyptus wood, leather, marble and rattan are used throughout to create a warm, relaxed ‘floating villa’ ambiance.
