Fun Facts
🤝🏽 SERVED MANY BILLIONAIRES:
From 2014 to 2024, the vessel served as a support yacht for Gabe Newell, co-founder of the game giant Valve, she was at that time named “DAPPLE”. ‘Dapple’ being the name of a donkey in the classic novel ‘Don Quixote’, in which Gabe took a lot of inspiration from for naming his yachts.
In early 2024, she was sold to Mark Zuckerberg to serve his main and brand new 118m mothership “LAUNCHPAD”. He named “WINGMAN”.
Not even a year later, Mark sold her to Nancy Walton Laurie, heiress to the Walmart fortune. She was naming the vessel “KALM” and is still now the support vessel of her main mega-yacht “KAOS”.
📦 AMENITIES & THE TOY BOX:
”KALM” is specifically born to be a heavy-duty ‘support vessel’, sometimes called also ‘shadow vessels’. These type of vessels are almost almost following their mothership, which is in most cases a bigger (and better looking) superyacht.
Their purpose is to carry anything and everything that the owner doesn’t want to keep in his/her main yacht. That might be an helicopter, boats or even small yachts, sometimes even submarines ect…
”KALM” features:
• a professional dive centre (70sqm): This is one of the vessel's highlights. It includes a high-tech diving setup with a hyperbaric decompression chamber - a critical safety feature for deep-sea expeditions
• a submarine: The vessel was designed to carry and launch a Triton 330 submersible (a 3-person submarine), allowing guests to explore the ocean depths without getting wet
• a commercial helipad: Unlike standard touch-and-go pads, this deck is fully certified for commercial operations (LY3/MCA). It can handle a takeoff weight of 5,000 kg (large enough for an AgustaWestland AW109) and has refueling capabilities.
• a hospital: While she has luxury cabins for 6 overflow guests, the ship is equipped for serious expeditions, featuring a designated hospital berth for medical emergencies
• huge deck space: she boasts 275 square meters of open deck space, which can be loaded with jet skis, tenders, land rovers, or even shipping containers of relief supplies
