The Biggest Yachts in the World

Welcome to the list of the largest yachts in the world, ranked by length, volume (gross tonnage) and width (beam). While the largest yachts have historically been ranked by length, some recent lists rank yachts by volume; here, we provide an updated list of the longest yachts and the largest yachts by volume, along with the widest yachts in the world (beam size).

We also provide two additional rankings for the largest yachts currently being built (by length) and the largest explorer (expedition) yachts by length. The lists for the largest by length, volume and beam include yachts owned by individuals, companies and heads of state, with ownership type notated in the tables.

All tables include both sail and motor yachts, except the explorer yacht table, of which the largest are all motor yachts. All tables include currently impounded or seized yachts (mostly Russian-owned) that are not sailing, but are also not under demolition. These tables still include yachts undergoing refits, but not demolished yachts.

Sources and Methodology

We collected all data between June and September 2026. Our primary sources include Yacht.com internal records, Boat International information through its market intelligence platform, BoatPRO and SuperYacht Times information via its SYT iQ system. Additional secondary sources include YachtBuyer, Superyachts, YachtWorld, Megayacht News, Moran Yachts and Admiral Yachts.

We defaulted to Boat International measurements when SuperYacht Times and Boat International differed. Boat International tends to use the class/registration dataset for registered length, which is based on strict registry/classification-style measurement rules, while SuperYacht Times uses the original design stats. SuperYacht Times also rounds the numbers and is less strict by including removable parts in the length. Boat International follows a specific registry rule set, making it more precise.

One exception is when a yacht undergoes a refit or remodel, and Boat International tends to have older data than SuperYacht Times. In those cases, we researched the refit and identified the correct stats. Sometimes, only certain stats were updated on either site after a refit, not all of them. In those cases, we researched the refit thoroughly and identified all the latest stats, which could be a combination of what Boat International and SuperYacht Times show.
