List of motor yachts by length
Updated: Wikipedia source
This list of motor yachts by length, is a table of the world's longest active superyachts, with an overall length of at least 75 metres (246 ft). These boats are also known as "megayachts", "gigayachts" and even "terayachts", usually depending on length. It has been generally accepted by naval architects and industry executives that superyachts range from 37 m (≈120 ft) to 60 m (≈200 ft), while those over 60 m are known as megayachts and boats over 90 m (≈300 ft) have been referred to as giga-yachts. This list includes both vessels owned by heads of state and those owned by individuals or companies. Excluded are the new residential "gigayachts" such as The World or Somnio, which are in a class of their own, halfway between a private yacht and an ocean liner. Pleasure vessels longer than 24 m (78.75 ft) are required to have a licensed skipper on board under UK regulations.
