List of motor yachts by length

This is a list of the world's longest motor luxury yachts, with a length of 60 metres (200 ft) and up. These boats are often known as super-yachts, mega-yachts and giga-yachts, usually depending on length. It has been generally accepted by naval architects and industry executives that super-yachts range from 120 ft (36m) up to 200 ft (60m), and mega-yachts are over 200 ft (60m). The only legal distinction is between yachts above 24 meters and below as those above 24 meters are viewed as a yacht and therefore must have a permanent crew on boat. Yachts over 300 ft (90m) have been referred to as giga-yachts.
