List of motor yachts by length

Wikipedia:

This is a list of the world's longest motor luxury yachts in order of their length. While length closely correlates with other measures of size such as tonnage (a measure of volume), or accommodation area, or displacement (a measure of yacht's weight), the correspondence is not exact, and the rankings should not be taken as a definitive ranking of size.

Whilst many businesses and organisations use length as an indication of the general trend, and the below is fascinating for the lay person, the true statistic of a yacht's size is its gross tonnage. Not to be confused with weight/displacement, this is in fact a measurement of a vessel's volume, what it can carry and accommodate.

Here's the top 5:

1. Roman Abramovich - 548'22" (167.1m) - Eclipse
2. Sheikh of Dubai - 524'10" (160m) - Dubai
3. Sultan Qaboos of Oman - 508'53" (155m) - Al Said
4. King Abdullah of Saudi Arabia - 482'3" (147m) - Prince Abdulaziz
5. Crown Prince Sultan of Saudi Arabia - 456'10" (139m) - Al Salamah
