The founder of Amazon is the richest person on the planet, so it’s only logical that he owns one of the largest yachts in the world. The billionaire, who has a current net worth of just under $200 billion, has commissioned a 417-foot gigayacht set to be “one of the finest sailing yachts in existence”, according to the book Amazon Unbound by journalist Brad Stone.

It will be so enormous in fact that a second smaller yacht has been commissioned as its support vessel with its own helipad. Built by Dutch shipyard Oceanco, project Y721 will be the largest sailing yacht ever built in the Netherlands and will likely cost upwards of $500 million. It's so big in fact it will reportedly require the historic Koningshaven bridge in Rotterdam to be removed and then rebuilt so it can sail out to sea.
