Russian billionaire Andrey Melnichenko is building the largest sailing yacht ever, according to Boat International.

The boat will be approximately 468 feet (142.81 meters) long — or about 1.3 times the length of a standard American football field.

That, as noted by CNBC’s Robert Frank, would dwarf the 289-foot-long “Maltese Falcon” unveiled by Silicon Valley venture capitalist Tom Perkins in 2006 and considered the largest privately owned sailing yacht in the world.

The yacht cost $US451 million to build, according to the Daily Mail.

This new “sail-assisted” yacht with be called Sailing Yacht “A”.

It’s not the first mega-yacht Melnichenko has built. He also has a 394-foot motor-yacht, called Motor Yacht “A,” which is filled with advanced technology, Baccarat crystal, and security systems.

Melnichenko, whose net worth is estimated at $US8.4 billion, founded the fertiliser producer EuroChem, the coal producer Suek, the power generator SGK, and the pipe exporter TMK along with Sergei Popov.

Correction: A previous version of this post listed incorrect details about the yacht, and listed Mr. Melnichenko with the incorrect age.
