Bill Gates | The Serene | $330 million

At this point, you’ve seen Bill Gates’s $40-million private jet and massive Medina compound Xanadu 2.0 worth over $131 million. To his credit, even with those two combined, his multi-billion net worth of an estimated $126.6 billion still leaves him with so much more luxurious belongings. One of which is The Serene, a massive 439-feet mega yacht that is worth $330 million.

The Serene is a mega yacht worthy of a tech titan such as Bill. It can travel long luxurious cruises and can host 24 of its friends, family, and business associates, plus 52 other crew members to accommodate their safe travels. Among the mega yacht’s lavish amenities are a salt-water swimming pool, a sundeck swimming pool, a gym, an elevator, and a professional kitchen. Moreover, it also includes a movie theater and also a helipad as well as a submarine garage. If you can afford it, Bill offers The Serene for $5 million per week.
