Microsoft Word and Excel architect Charles Simonyi spent nearly 20 years living and working aboard a $100 million, 233-foot military-style superyacht with its own helipad

Charles Simonyi, known for Microsoft Word and Excel, avoided property taxes by living on a superyacht. His custom-built vessel, Skat, offered waterfront views and freedom from regulations. The yacht featured a minimalist interior inspired by art galleries and advanced noise reduction engineering. Simonyi later transitioned to space tourism before upgrading to another large yacht. He sold Skat in 2021, continuing his unique lifestyle choices.
